Hobbyking bat 1 rc land yacht: all you need is wind and a sail.

RC Boat Staff August 17, 2016 Reviews 778 Views

IN THE WIND

After wrapping my head around how the sail system works, it was time to head outside and give this wind-powered 3-wheeler some stick time. I gathered up the BAT, the transmitter and the ambitious E-Man and trekked out to the parking structure outside our building. It was a beautiful day, however there was very little wind; the one thing we needed. We gave it our best but without that wind the BAT 1 barely moved. Back to the office we went.

Let me tell you that having the BAT in my office on the bench staring me in the face was like getting a new bike for Christmas only to find out it’s raining outside. It was four days before Mother Nature finally decided to cast some wind my way, so it was back outside to give the BAT another try.  AUTHOR’S OPINION

Anything RC is fun for us and when the BAT 1 rolled into the office, we were pretty excited to try it since it was something a little different. Once you get it going (that is, once there’s wind), it’s actually really fun to drive. The controls are similar to a regular RC car so if you have any experience driving, you’ll pick this up in no time.

• Electronics already installed
• Easy assembly with very few parts
• Low-drag foam tires
• Only requires four “AA” batteries
• Requires wind or it won’t move

Transmitter on; switch on. Steering working; check. Boom swinging; check. After my ‘all systems go’ check, I set the BAT down and immediately it started speeding away as the wind caught the open sail. As I approached the end of the parking area, I applied brakes on the throttle to cinch the sail in but found that the BAT doesn’t actually have brakes! Cinching in the sail only limits the amount of air that it gathers; slowing down is simply a matter of it losing speed! Panicking a bit, I cranked the wheel and the BAT aggressively whipped around and almost immediately the sail swung around to the other side. Ah, now I’m getting the hang of it. No matter which way the BAT is pointed, the sail will swing to the ‘wind’ side as long as you have the throttle open.

I drove the BAT around for what seemed like an eternity before Edwin graciously noted that he’d been done with pictures for about 20 minutes! Yes, the run-time on this thing is unreal; as long as your “AA”’s are fresh and there is wind, you could go all day!

FEATURE BREAKDOWN

• Since the BAT is powered by wind, it only needs the giant sail for movement. The main sheet line extends out of the hull and is attached to the sail at one end and a second servo on the other. Connecting the sheet line is a little tricky … it took me a few tries to figure out exactly how it works. The throttle on the transmitter actuates the sail, but here’s the trick: when you pull the throttle on the transmitter (similar to accelerating in a normal RC car), it provides slack in the main sheet line and allows the sail to swing, catching air and moving the BAT forward. When you push forward on the throttle (similar to braking on a normal RC car), you are cinching in the main sheet line, or preventing it from swinging. This keeps the sail inline with the BAT and limits the amount of air it can catch, effectively slowing it down. Trust me, it’s weird at first but you’ll get the hang of it.

Hobby King’s BAT1 Land Yacht: We Want to Try One [VIDEO]

Name any type of full-size vehicle, and you don’t have to look too hard to find a mainstream RC version you can buy. Unless you’re talking “land yachts”…you don’t see those every day. Hobby King has that niche covered with the BAT 1. It’s as simple as RC gets, with wind power providing the motivating force and the simplest of simple chassis to get down the road. There are two servos aboard: one to control the steerable front wheel, and one to flip the sale for maximum wind-catching capability. And the BAT 1 is pretty big–28″ long, and 39” to the top of the sail. Driving the BAT 1 looks like an interesting zen challenge that we want to try–how about you?

Pricing $108 for an RTR, $83 for an ARR, and $70 for the kit version. see below for official Hobby King info, and as always you can see the latest new gear daily in our Hot News & New Stuff forum .

From Hobby King:

Land yachting combines the grace of sailing with the thrill of motor racing. It’s great to watch your land yacht skimming across smooth hard sand or a large tarmac area at high speed and with no noise just using the wind.

Full size land yachts hold speed records of over 126mph sailing at 3-4 times faster than the wind that propels them and now you too can enjoy the challenge and thrills of land yachting with the HobbyKing Bat 1 RC land yacht.

The Bat 1 has been designed by a renowned RC and full size land yacht pilot and it is available in 3 versions, “Almost Ready to Run”, “Plug n Play” and in “Kit” form. All versions have a simple, rugged construction and are very straightforward to assemble. The Bat 1 utilises just 2 channels, one for steering and one for controlling the sail, it also has low friction ballraced wheels for super smooth free running and a colorful eye catching sail finishes the Bat 1 off nicely.

Comments from the designer of the HobbyKing Bat 1:

• It’s like flying a boat on wheels • Land yachts achieve suprisingly high speeds • They travel faster than the wind driving them • Virtually maintenance free • Simple rugged construction • The radio gear is well protected against impact, dust, water and mud • Fast, clean, quiet and fun • No messy expensive fuel or batteries • No noise or pollution • Pure simple fun

The Bat 1 (ARR) almost ready to run comes complete with 2 servo’s, a 2ch HK-GT2B rechargeable transmitter and receiver, all that is required is a small amount of assembly and 4 AA batteries for the receiver and servo’s and you’re ready to go.

Features: • Pre-molded 2 piece hull with decals applied • Carbon mast, boom and rear axle • Large ballraced main wheels • Pre-installed ballraced steerable front wheel • Shaped eye-catching mylar sail • Rugged construction • Very easy and straightforward to assemble • Pre-installed servo’s • Pre-installed receiver, switch and “AA” battery holder • Simple exciting fun

Specs: Length: 730mm Width: 500mm Height: 1000mm Sail Area: 0.15m² Weight: 692g (without batteries and receiver)

Included: 1 x HobbyKing™ Bat 1 Land Yacht 2 x Servo’s 1 x HK-GT2B Transmitter with Li-on battery and USB charge lead 1 x HK-GT2B Receiver 1 x “AA” battery holder with receiver switch

What our customers say about Racing Sparrow

Being a complete novice, I purchased your book a couple of years ago and built two racing sparrows. Building on this experience I then went on to build, from scratch, an IOM (Triple Crown design). I've since joined a local club and sail virtually every weekend. I would just like to thank you for your endeavours which have allowed me to enter a world I never thought was in my reach.

John Sterland, Australia

Coming upon your book, "Build your own Radio Controlled Yacht" in the Napier Public Library, I am hugely impressed. The combination of your superb photos and illustrations with your easy writing style make it a standout publication and I hope it does well for you.

Richard Spence, New Zealand

Thanks for an excellent design in your RG65. I trialled her again today in a solid 20 knots gusting higher. Even so in a steep chop and fingers off the rudder she drove upwind remarkably well, balanced perfectly. Very impressed that a model boat can handle that with a large rig. I found the book excellent. Ive built several big boats, plus a few skiffs and without that resource building such a good boat would have been impossible.

Price History

The plans include written instructions, CAD drawings and a bill of materials. These instructions have been tested thoroughly so that you can enjoy building your model with ease. 

Each model requires a 2-channel radio with one steering servo and one arm type sail servo.  These can be purchased at www.towerhobbies.com . If you do not have any radio equipment we recommend the Futaba 2DR 2-Channel AM/1 S3003/1 S3801 Radio/Servo package.  For the sail control any arm type servo with 150 in-oz of torque or more is adequate.

If you're interested in designing your own model, but want a proven design to work from, the plans for each model also provide a good starting point. 

After you come home from a pleasant sail, the LS models break down and hang easily on a wall with only two pegs.  They fit easily into any size car and set up in about 30 seconds.  With such durability and easy use, these models are sure to be hours of fun all year long.

In addition to complete tested designs, I also offer free RC landsailer design tips & tools for those of you who prefer to design your own models from scratch.

This thing is a blast to run. It went together very easy. The only modification I made was to add a "goosneck" to connect the boom to the mast...I used Velcro and it works very well. Without the goosneck the boom allowed too much wind to spill from the sail. See my video.

Simple, robuste, dmontable sans outils, donc facile emporter et utiliser partout... Une conception sans reproches.....Juste un tout petit quand mme, l'interrupteur aurait pu tre plac un peu plus en arrire, il butte contre le pack d'accus ou contre le rcepteur lorsqu'on referme la partie suprieure du "fuselage". Reu 4 jours aprs la commande, 1h de montage (version Kit, j'avais dj une radio volant en 27mhz AM, 2 servos std futaba s3001 et un pack d'accu NiCd 4 lments la place du porte-piles livr). Essay le soir mme sur la piste de mon club d'aro .... Un second en version ARR est dj en commande pour se tirer des bords avec un copain....!!! Genial...............!!!!!!!!!!!

Fantastic bit of kit....easy to 'sail ' once set up....hope there are spares, though, had about 4 outings on tarmac surface, the 2 rear wheels showing signs of wear already....perhaps best to use on short grass or something more forgiving. Overall, a brilliant design. Thanks again, HK!

I have toyed with the idea of building an RC Land Yacht as a little project and today I have come across these Land Yacht Kits from Hobby King.

That looks like good value for $100 bucks or thereabouts.  Go for it!

You always cost me money........ I couldn't resist some mini pole dancing even though the courier to West Aussie was $47.50.

From the time I ordered/payed for it, to when they sent me an email that it's in despatch for courier was 9 minutes. That's right   9 minutes.

Order shipped from NSW hobbyking.

This is an email to inform you that your item has been dispatched from our NSW warehouse. 2/07/2015 6.59am.

Can this be really true!!!  This is a first for me from a big international company.

Geez, Jas at BrisKites, there is a big company out there that cares "almost" as much as you guys.  

Australian Warehouse is a fair bit quicker than the International one for processing orders.

Harsh Gozzy!!!  Nah Jas has been very good to me as a feral west aussie. 

Bloody grapevine is as worry. I had 3 mates here for morning smoko and they squeaked.

Haven't been to town to check if it's here yet. I would think not as gear from the East coast always takes a couple of weeks to get here.

I picked mine up yesterday and I'm just assembling it. It's quite a cute little yacht and a well made model.

Took me 1 1/2 hours total to put it together.

Got delayed yesterday, as a mate turned up with some beverages.

I used my own standard size metal gear servos and receiver.

Of course that stopped any hint of wind didn't it.

So spent the day mowing the lawn.

3D Printed Folding RC Land Yacht - MUSHU

Introduction: 3D Printed Folding RC Land Yacht - MUSHU

This instructable goes through the process of creating a folding RC land yacht through 3d Printing.

This project fits into the IRCSSA class 1 rules (http://ircssa.org/class-standards/) which is a development class of RC land yacht using a box rule (all of the vehicle must fit within 750mm length x500mm width x 1000mm height) This land yacht is designed as a fun simple project to get into RC sailing and 3d printing, not as a regatta leading race machine. 

I will walk through the steps of designing this yacht, the principles of which can be applied to custom designing your own land yacht. Feel free to do this if you have the CAD knowledge or take my parts and print these as they are. 

For simplicity I have used a mast and sail from an easily accessible RC yacht class. The parts for this could be replaced by a cheaper home built assembly but lightweight and quality masts and sails will make for a better performing boat. The only part that would need to be modified is the mast step which currently accepts a 5mm tube.

The name of this design 'MUSHU' came in part from the rig. The mast and sail are from a Dragon Force 65 (DF65) RC yacht. This project is for the land though, so the first land dragon that came to mind was Mushu from Mulan that has been a regular at my house with a soon to be 3 year old running around.

If you have any questionsn about the project feel free to message me or comment on this instructable.

Step 1: Design (Skip If Using Provided 3d Print Files)

The first step in designing this land yacht was assembling all the required RC gear. This really dictates the layout and physical size of your land yachts ‘body’ 

For a functional land yacht you only need a very basic RC setup:

• 2chanel transmitter & receiver
• 1x battery pack
• 1x servo switch (on off switch)
• 1x steering servo (i used a 17g servo) 
• 1x sail control servo (I used a 37g servo)

If your like me you wont be able to resist plugging everything in and seeing how they move… Go for it. This will help you see what your servo’s range of motion is. 

Playing around with different layouts for the parts early on helps get an idea of what the body shape could be to accommodate all the RC gear. The second image in this step with multiple assembled layouts shows a couple of different options I played with before settling on the compact option at the bottom.

Once I had all the parts assembled I arranged them roughly where I thought they could go and measured the overall dimensions. This became my guide for the body (see plan view sketch image). with key internal dimensions.

My final shape looks a lot more refined than the orange box shown in the images. However these early prototypes were really helpful to see the RC parts inside this box. This showed me which areas had heaps of extra space, where wires could run etc and from that I was able to remove some of this empty space and create a more curvy design (See sketch and two part image)  

While this shape worked and everything fit inside nicely, I wasn't happy with the amount of support material needed to print the hull. I changed the model and turned the two part hull into a three part hull. This meant that very little support material was needed for the print, but the model now could be printed with a coloured middle section adding a bit more interest to the project. Win win! (See CAD images)

Figuring out how to join the main hull to the wheels was relatively straightforward. I had some Aluminium 10x3mm solid section spare from another project that I wanted to use. I designed the additional parts to accept these with small bolts used to hold them in place. There was a lot of trial prints to get all of this right. The final image shows a bunch of the bits and peices that I printed on the way to the final design.

For the Wheels I made my own hubs to take some bearings in an attempt to get them running a bit smoother. The sizes of some of these parts will vary depending on what wheels etc you have on hand. I made my wheel hubs fit these tires - https://www.amazon.com.au/gp/product/B09D3NNGKJ/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

Feel free to use whatever wheels you can get your hands on. I have read a lot of guides on roller blade wheels being ideal for RC Land yachts. 

Step 2: Print All the Parts!

If you are going to design your own parts then you have quite a few hours of fun ahead of you. Otherwise use the parts attached here that I have designed and you have quite a few hours of printing ahead of you!

Most of these pieces have been designed to print without support. See below at the end of this step for quantities, support and infill settings that I used. Feel free to play around with these settings as you see fit. I haven’t had any breakages from the parts on this prototype to date. 

Clean up any of your prints that need it with a bit of sandpaper or files. I have left most of mine as they came of the printer as i’m not too worried about the print quality. I printed my parts on an Anycubic Mega Pro with only minimal tuning to date - One day i’ll get better print quality but i’m happy with this for now.  

Check all of your nuts fit into the allocated holes on the printed parts, as well as your mast and any bolts. 

Most of the nuts should be a bit of a pressure fit but if you want to make sure they always stay in place feel free to take some superglue and fix them in place. 

Printing quantities and support:

All parts .16mm layer height. .2 infill.

Hull bottom - 1x. Needs supports for where the steering servo goes only.

Hull middle - 1x. No supports

Hull top - 1x. no Supports

Rear wheel axle - 2x. No Supports but print vertically

Fron twheel attachment point - 1x. No Supports

Front wheel bracket - 1x. No Supports

Front Wheel Axle - 1x. No Supports

Front wheel lock nut - 1x. No Supports

Wheel Hub - 3x. No Supports

M4 Lock nut - 3x. No Supports

Attachments

Step 3: Cut Aluminium Bar

Take your Aluminium bar and cut two lengths at 227 mm long and one length at 400mm long

Give the ends a bit of a sand or file to clean up any scrappy bits your hacksaw may have left. 

Dry fit the Aluminium bar into each of the parts that join together and mark holes using the 3d printed parts as a guide to mark where your holes need to be drilled. (check the images later in this instructable if you arent sure where these parts need to line up)

Use a punch and make a point on the Aluminium to help center the drillbit when drilling out holes in the bar. This step helps stop the drill bit from wandering off your mark and leaving your hole drilled out of place.  

Drill out each hole and test the fit with your 3d printed parts and nuts and bolts. If need be drill the holes larger to fit everything together. 

Step 4: Assembly RC Parts & Hull

Firstly before fitting all the RC gear and bolting the hull parts together, attach nuts inside the base of the hull. Use a little bit of superglue to hold these in place. You won’t be able to access these later in the assembly. 

Assemble the RC gear inside the hull. It’s a good idea before you screw the hull together to test the RC gear is all working as desired, Which port on your receiver will determine which control on your transmitter is used to adjust it. Check your transmitter/ receiver manual for information on what to plug in where, also for info on how to ‘bind’ your transmitter to your receiver. Make sure you do this!

With 4xM3x20mm bolts assemble the three parts of the hull together. The fit is tight enough that no nut is needed on the end of these bolts. 

Fix the servo’s in place using 4g x 9mm screws. Pan head or countersunk head both work here. 

Step 5: Join Aluminium Bars

Flip the hull over and attach the long Aluminum bar to the front of the hull, and the shorter pieces to each side. You can tighten the front two bolts as this won’t move again but make sure the bolts on the arms are firm but not overly tightened. These two bolts as shown are the pivot points when the arms are to be folded up. 

Attach the last two points with your M4 lock nuts (See the last image). These are designed to be large enough to screw together by hand. These bolts unscrew to allow the arms to fold in for transport when the rig is off.

Step 6: Assemble Front and Back Wheels

Both back wheels use identical parts and should be assembled as shown (First image). Take the wheel bearing and press this into the tire hub. The inner ring on the bearing will fit over the round part that attaches to the aluminium bar (axel bracket). Fix these in place using a 8Gx16mm pan head screw as shown. Fix the axle bracket to the aluminium bar using a M3x20mm nut and bolt. (You can use smaller bolts in some parts or cut these bolts down but for this instructional i've tried to keep the different sizes of bolts to a minimum) 

Assemble the front wheel assembly as shown (Second image) The front wheel uses two M4x30mm bolts, one as the wheel axle and one to attach the steering pivot point to the front bracket that attaches to the Aluminium bar. 

Attach your steering arm to the steering servo and attachment point at the front wheel assembly. This might need some fine tuning to get the right amount of turn out of your servo. To get started I used two steering servo arms with attachement points like the one shown here. Then i Taped the two bars together with some duct tape as a temporary hold. This allows you to make some adjustments if need be.

Turn your RC gear on here and let the steering servo center. Unscrew the servo arm and re-attach this in place with the front wheel centered. You should now be able to turn the wheel in both directions an equal amount. 

When we get sailing you may find that you need a longer arm on your servo or to use an attachment hole on the front wheel assembly close to the pivot point to get more turn. My turning circle was quite large at first but with some adjustments i'm happy with the turning now.

Step 7: Attach the Rig

Using some fine string (dyneema cord that is used for many model RC yachts is ideal) Attach a jewelry clip or similar clip to both the back aluminium bars and the front aluminium bar. These serve as attachment points for the stays that hold the mast in place. 

Tie a reef knot https://www.youtube.com/watch?v=aprfVTaxkk0 to attach this little bit of string and burn the ends of the rope to avoid fraying. Dyneema cord will burn easily so go careful with your lighter here. 

Take your Donor mast from your DF65 or similar and fit it into the attachment point on the hull. Attach a forestay and two side stays. And pull them both back to where they attach near each wheel. Tie a loop in the end of one making sure that you are putting a bit of tension on the mast (pulling it backwards) when this loop attaches to the jewelry clips. Pull both stays back to the centre of the boat and tie the other stay at the same length as the first. This will help ensure the stays pull the mast symmetrically backwards. Clip both of the stays into place. 

Attach a bowsie to the lower end of your forestay and tie this off so that you can put tension on the mast. Attaching cord to these bowsies can be a bit tricky and needs a nice clean cut on the tip of your cord. If you are struggling with these check out some YouTube videos on tips and tricks for bowsies. 

For the final rigging step attach another bowsie to some cord tied to the end of your boom. Attach the other end of this to a jewelry clip or similar and tie a loop of string onto the end of your sail control servo. Make sure to give enough play when fitting the bowsie that your sail can be pulled tight when the servo arm is pulling as tight as it will go as shown in the below image. 

All off your rigging is now complete and can be quickly assembled and disassembled by loosening the bowsies and unclipping your jewelry clips.

All that's left to do now is go sailing!

I will be working on a box for my boat to safely store the sail away from damage. Two pieces of cardboard and some tape will do for now!

Hope you have enjoyed this intractable and I welcome any comments or feedback.
