Flight Stabilizer for the Towel

[Dan]

So I just received the new orange RX flight stabilizer ( http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=25448) from HobbyKing with 3 gyros and successfully installed it in my 4th generation Towel. 

Took a bit of tweaking and a V-Tail mixer to function. I also had to reverse the orientation of the stabilizer, so not the direction of flight side faces the rear of the wing. Tried every other wiring option but one thing or the other was reversed. 

Flight characteristics:

Serious instant constant over compensation.  Turned down the gyros about 20% and it was a little better. 

Overall it prevents you from any extreme moves and definitely counteracts w d and turbulence. Where I fly it's always windy, usually prevailing from the south. So flying down field I have a tail wind and up he field a heavy head wind. The gyro's really help with it. Got my longest flight to date and even hand caught the plane for a landing.  I've seen Breck do this at last years Maker's Faire but never managed it myself, until today. 

So overall for $15 from HK + $5 for the mixer it's pretty sweet. Also FYI the HK stabilizer is built around an Arduino so those inclined could hack the software to better suit the Towel. If anyone takes this on please post the script for the community. 

I'm posting a couple pics of my current setup here as well.

Sky's the limit,

So I took my Towel out flying again yesterday this time turned the the yaw on the gyro down all the way since there is no yaw (rudder) channel on the towel and got a much better response.  Now my towel flies so well.  I see HobbyKing has another low priced stabilizer that has a flying wing setting for only a couple bucks more. 

Hobbyking i86AP Flight Stabilization Control Board

 lacks the case but is also lighter.  I might try this when back in stock.

BTW has anyone added rudder servos to the towel?  Seems like it would be pretty easy and of course you don't have to use them but could always trim for better flight.

Glad you got it working. I have had good luck with horizon sensing
auto pilots like FMA makes. Expensive but a very nice way to teach.

Wow thanks for the tip, that's an ingenius way to level a plane.  The Co-Pilot CPD4 looks like it would work well with the towel since it only adjust pitch and roll.  And it's less than half the price.  Have you tried that model?

I have used an earlier version of that system. It worked well. I am a little
concerned about how it would work with an out of trim airplane but worth
a try.
