BlueSkyRC FPV Tricopter

Just wanted to share that we now have the Laser-cut plywood Tricopter frames in stock. I (and others) have been beta testing the frame for the last couple of months and I am very pleased.

The kit includes all the plywood parts and the nylon hinge and retainers. It is designed for the Square 10mm booms (GWS Slow Stick size). I have been using the aluminum filled with bass wood. Others are finding great solid results with the fiber glass with bass wood inserts.

I have been flying the Tricopter in sport light aerobatic mode for quite some time and within the recent weeks have mounted my FPV gear and have had a awesome time with it.

The kits can be had from BlueSkyRC.com

Looks like a nice kit... do you find the counter rotating prop helps much with the tri?

I like the fact that it comes with a halo that protects the controller. I think it would be better if you made the tricopter foldable though as it is one of the biggest advantages of the y-shaped platforms.

I have not tried the Y6 yet, but I really want to.

You can get the Y6 motor mounts for this kit from here:

I really love the Tricopter -- for both sport aerobatic flight and FPV. The front left is counter rotating and the right and back are normal. This requires that you have a little tilt to the right on the tail motor when you trim it out.

Yaw is smooth. In fact I can do a hovering yaw rotation and keep it very smooth.... a little better than my Quad.

Yeah, the kit could easily be modified to do this. You could easily add a type of hinge screw to the front arms that would allow them to fold back. This is wood and super easy to work with. It is light and strong as well.

Both of my tris are using normal props all around, wasn't sure if it was worth it for the tri, but i have some props on the way for the quad so I can try it.

how are you attaching the hinge to the wood parts? glue or did you bolt/screw it?

You can bolt or screw it. Working with the wood is really great. Drill out the laser holes near the size of your screw then thread your screw in it.... remove the screw then CA harden the new threads in the wood.

You can also drill into the nylon hing and mount through the motor base into the nylon and tap into the nylon. It works great. We have 3 of them flying right now. 2 hear in AZ, and in Ireland. The hinge is super strong... as always with the Tricopter, the metal gear servo may take a beating on tumbles and really hard landings, but the mount has been better than I expected and I am very pleased with it.

Using the counter rotating props on the Tricopter is totally worth it. it reduces the amount you have to adjust the back motor. Also you probably have to fight yaw when you gun up the motor. You should try the counter rotating prop on one of the front motors -- I like them to rotate in toward the center of the craft.

Throw in just one Y6 motor mount in the kit and you can sell them as a Tripcopter/Y4 multi rotor.

Just some theory to consider During fast forward flight with counter cotating front props:

A) If the Left arm prop is turning clockwise
and the Right arm prop is turning Counter clockwise
You will be generating maximum extra lift at the outboard ends of the props,
which should help stability.

B) If Left is CCW
and Right is CW
The maximum prop lift will be generated at the inboard ends of the prop which is less stable than the A configuration but more maneuverable

I would be interested to know if it is a noticeable difference in flight for a Tri in case anyone tries this out.

This is the Advancing/Retreating blade theory from Helicopter flying and is what causes single rotor Helis to start rolling towards the side of the retreating blade in fast forward flight, and also what limits the top speed of full size Helis.

Tri's with counter rotating props don't have that speed limitation

We need some full size Tri's

Using a Y4 configuration is reasonable yaw possible without the motor tilting mechanism?

I ordered a tricopter frame last night. How dependent on the tubing size is the design? 10mm = .39 inches, so would a .375" square tube work, or would the .015" difference cause problems?

How quickly can you typically ship?

10mm fits perfect and would be the best option and the boom slots help ensure a snug straight fit. It would be possible to wrap the booms with tape or something that would cause them to fit snug then set screw or bolt them in the frame. I know some have even used epoxy.

As for shipping, they normally go out same day or within 24 hours. Yours is boxed and shipping paid for and labeled. Going out this morning.

Flippin' sweet. I went ahead and got the LHS to order me some 10mm aluminum slow stick booms, and they'll be here Wednesday. With a little luck I'll have it in the air next weekend.

I would be happy to post some video and a short review if you like.
