NEED Help with a New Idea

[vector357]

I have been thinking, Yea I smell smoke to, We all have Gyro's that control the tail of our Heli's, but does anyone know how 2 more gyros forming an X and Y axis for Fore and aft, as well as Left and Right yaw can be created?

My idea is this, If 2 more gyro's can be combined so that if the Heli is not receiving any LR, or Fore or Aft stick input, that the Heli comes back to a Level Hover by it's self.

I'm Interested in Any Ideas on how to achieve this. I know it has been done on larger heli's, but How could I do it on an RC Heli?

Many Arial Photography guys are using this to keep their heli's put when snapping pics, almost handsfree. It will drift with the wind, but does an amazing job.

Definetly can be done, but one thing you would have to create is the part where it knows how to "right" itself, or return to a pre-determined level. Reason I say that is, think of a tail rotor gyro, .You yaw the boom one way or the other. The gyro holds that position where you left it, and doesnt return it to center. Therefore, if you were to pitch the nose down, with a gyro on the pitch axis, it would maintain that angle of pitch and wouldnt knowingly correct itself to level unless you designed a system to tell it what is upright and level. You may be able to incorporate technology from for of the flight training gizmos that supposedly rights and airplane when the controls are released, as it is programmed, or zeroed so it knows what upright, level position is.

there was a guy at my fiedl once that had a FMA autopilot, did about what your saying tank, when you turned it on that was the set 'level' and any time after that is would return to that postion once the sticks are center,, i dunno if the reaction time would be fast enough for helis,..

There is actually 4 or 5 systems that do this. Including but not limited to;
Robb Heli Command
AP2000i
NRI
Carvec


There are also system that use 2 additional gyros to to able and remove the flybar

COOL. I have been reading about the Nex Star and the FMA's Co-Pilot, and it looks like the Co-Pilot wins hands down. However this posses a problem for me. The basic system they have will only work with an X Y axis swash, and the more advanced one comes with a programmable receiver. I currently use the DX6 radio system, and it works off a 3 point swash under CCPM.

Does anyone know of a system that will work with the radio system I already have? I have too much money tied up in this to just dump it.

Don't get me wrong, I live where it is always real windy and Gusty, and I have learned how to control and correct even in an Out of Control situation, but I would love to be able to have something like that to use to take pictures with my Heli.

So far, I've seen 3 different types of these, ranging from $70 to $500. The Robbe one for five bills, looks like it would work with Any system, but Who has 5 hundred dollars to piss away, certainly not me.

Many AP guys use the 2000i and it is only $200

Sounds like something I would like to check out. Do you have a Link for this one? Also does it handle CCPM? Both my Heli's are CCPM

[BladeBurner]

There are a bunch of vids on Youtube.com, just type in the word "helicommand" in the search box.

The spartan is pretty brilliant - it will handle any sort of ccpm and also do a "digital cyclic ring" (keeps the swash from binding when you put the RH stick in a corner.) Do a search on it on Runryder.com - there's some good reviews on it.
