Tricopters a great new choice to hover

Guys,

Just wanted to share this relatively new type of craft. These new Tricopters, quads (and more) are a really great. They are tough and easy to repair. They are to helicopters what epp is to foamy's. Also, easier to fly than traditional helicopters such as a T-Rex 450, carry more payload, get longer flights.

The little Tricopter I built powered by three blue wonders can fly batteries from 1000 3s to 4400 3s.

Great fun, just wanted to share with others who may not be aware of these amazing machines.

They are inherently unstable; but the new electronics make them easy to fly.

I figured if anyone would create a foam fuselage for it, you would.

Yeah, I saw your build thread on the T-copter. I'm seriously considering building a T later this year, but it seems everyone else is using larger motors/ESCs/batteries. There is a certain appeal to having a smaller T with BW motors. Have you done any payload tests with it? I'm guessing it should be able to handle something like a GoPro HD (~5 oz) pretty easily? Have you had a chance to try any aerobatics with it?

Can you give a quick rundown on the electronics and props being used?

As always, thanks for sharing your exploits!

Most of the guts I used are pretty familiar to a lot of the scratch built foamy crowd.

3 of 1500 kV or 1300 kV Blue Wonder or equal
3 of 12 A Mystery esc
1 of 9 gram servo to tilt the tail motor for yaw control
Rx, any type

To make it stable you will need either:
4 of HK401 gyro
or better but more work, Wii motion plus type controller...has built in gyros

1000 to 2200 3s battery

The airframe is easy to scratch build. It can be aluminum wood whatever is available.

Make the motors in a perfect triangle with the cg in the very center. This loads all 3 motors equally and makes tuning and trimming easier.

This is not a beginner helicopter, but with some time on a 4ch beginner copter and/or some simulator time it is reasonable easy to fly.

How long are the arms and boom on your T? Tri?

The length of the arms will depend on the stabilization you choose. For gyro stabilized (less tune-able) longer arms of about 15" will work well. For the Wii controls the arms can be much shorter but they don't need to be.

I'm making another frame with 10" arms now. The shorter arms make the loops and flips faster...more aerobatic.

Longer arms are good for fpv where you want things to happen slower.

So... some time on a 4-channel like the mCX2 or do you need fixed pitch or collective experience?

This seems highly interesting to me. Thanks for posting! I think it is great you are using Blue Wonder motors!

I built one a couple of weeks ago. I really like it. Here are a couple of videos of mine.

Great. Just great! Will you be posting details of the build, wiring, connections, etc.? I'd love to build this model!

I few one of the Parrot AR quads, but it was so stable that it was boring, decided not to buy. I have been looking at the Gaui though.

There's a lot of info in the Multi rotor forum.

If you can fly a MCX2 and hover nose in with confidence then you should have not trouble with a Tricopter. The biggest change you'll notice is that the Tricopter won't self level like the MCX does, it just stays exactly where you put it.

They are incorporating a self leveling function, and it seems they may have the bugs worked out. It uses the Wii nun chuck accelerometers in tandem with the Wii motion plus gyros to accomplish this.

I don't have much in the way of build details. Everything you need to know can be found in the multi rotor forum.

Here's a little video showing the capabilities of these great hovering machines. I continue to be amazed at the efficiency and also the great flying characteristics...which are possible due to the electronics.

Great flying Lead.. I really have been enjoying mine. I am just running the gyro setup. I might get a wii setup some day. Here is a video I did yesterday.

Nice flying Russ.

I started with gyros. They are far easier to implement. The Wii controls are a pain to implement; especially the first time; but they provide much better stabilization and tune-ability.

HK is coming out with a plug-n-play control board soon for a Quadcopter.
