So I ordered the parts to build one of these triwiicopters. I already have 2 tricopters and both are using gyros for stabilization. Now I’m starting to wonder, what are the benefits to using the wii motion? Will the tricopter be more stable with the wii than it will with 4 gyros?

probably a separate CPU for multiple Rx?

Decoding a PPM pulse sum requires nearly the same amount of interrupts. The work is just concentrated on only one PIN.
I don’t think it would reduce significantly the jitter.

Yes, for sure. The difference is real.

Look at this video: 3 gyro Telebee + 1 Esky

Tricopter (6 min 23 sec)

the stationary state is not very stable

and the last triwii one:

It's the same frame (23cm distance motor to center) and equivalent motors

You can find very stable config with 4 gyros, but with longer arms

handover via UART?

Thanks, thats what I wanted to hear. I use my tri copters for AP and video so more stability is always welcome.

this is a motor who was bad, I change the tree controler it's the same.

need to change my motor tomorow

wait and see

Any Tri-frames available you guys would recommend?

Y-UFO parts are the one I know if you want the standard three motors with servo tilt yaw control.
They should have a winner if they make a smaller nano version of a standard tri.

Finally got my wii's and chucks in. Even these fake motion plus's have the blasted screws with nonstandard nintendo screw heads. At least the chuck has regular phillips screws.

For anyone getting a chuck, don't get the MadCatz chuck from target. It might work but the chip is just a blob of black material. There is no way to tell which accelerometer is in it.

Yeah I had my eye on the Y-UFO frame, it looks like a nice start. I see you mention you bought the chuck too. I thought this code Alex is using does not support the chuck? Or are you using the Baron pilot code?

I'll start off with this to get familiar with what just gyros can do. My bad flying skills require a stable mode that gives stability similar to the walkera UFO5 so I'll check out the Baron project also. Then I'll come back here for round two when the chuck gets integrated

I have got both of mine form averticalview.com. Started off with their basic Tri and now building the Folding Matrix. See http://www.rcgroups.com/forums/showthread.php?t=1265051

Hey Bob,

Did you ever make it work?

I really like the price of the Arduino clone.

I have almost no experience with the arduino, or any other "chips". Is there a way I can modify the P I D parrameters without an LCD?

I don't mind having to re-upload sketches. Once it is set, I'll leave it that way.

Thanks for the project!!

Hi Sebastian

No, I haven't got it to work yet. I'm going to pick up another WM+ just in case I cooked the one I had. I did assemble the arduino and get that running OK. It seems the WM+ isn't starting. I get no controls at all, but my speed controls arm OK. Alex is helping me along. I really hope I can get this going, its hard to beat it for price or size. It is lots smaller than I thought.

See Ya

Alex - Is this something that can be easily adopted to a quad? Or is it strickly for a tricopter? Great work - I am waiting for my WII motion and I am ready to build it -

Hi,
There is already at least one existing quad options for WII motion plus+Nunchuk: Aeroquad.
However for a WII motion plus only quad version, the Triwii code could be easily adapted.
