Spektrum Autogyro set-up

[Roy Hill 3]

Hello chaps. It's me again with another silly question. I've recently purchased a Spektrum DX8G2 to use with the scratch-build auto-gyro, which is on the work bench. My question is.... which set-up do I use for an auto-gyro? Any help will be appreciated. Happy landings, Roy.

Depends how you have the pitch and roll servos set up for the rotor head control. If they both have to move for pitch and roll control then delta wing mixing if probably whats needed.

Auto gyros go as a fixed wing. I assume you have throttle, elevator, and rudder. The rotor is normally just a lifting device without servos.

Don, most autogyros have a pivoting head, which the servos tilt, depending on the set up the servos will either be set up as delta wing or conventional elevator/aileron.

Cheers Frank, didn't know that. I've built a couple and I assumed they were all like I described.

How does yours go Roy.

[Roy Hill 3]

Thanks Frank and Don. I thought that this bring a variety of answers. My autogyro will have throttle and rudder but no elevator. I have already built a prototype pivoting head which will be controlled by 1 servo for forward and back tilt and another for side to side tilt. Back to you, chaps!

[Don Fry]

But you have not specified, as Frank has already pointed out. Do they do pitch or roll. Or pitch and roll.

One will work as a delta. One will work as a conventional aileron/elevator.

[Frank Skilbeck]

Sounds like you need to set it up as a conventional wing, elevator will make it tilt forward and back and aileron left and right. On the elevator servo pulling back on the elevator stick will cause the rotor head to tilt back, left aileron will cause it to tilt to the left.

Have a read on the various autogyro threads for setting c or g and head angle etc.

Thanks chaps.

I am building a model RC gyrocopter, with three servos. one for rudder and two connected to the rotor head. What set -up do I need for the rotor head servos?

Should it be one  servo  for the aileron channel, and the other for the elevator channel as conventional fix-wing ?

Or should they be set up as V-tail?

I am using a Spectrum D8 Tx.

Any help would be much appreciated.

Thanks 

David

David, it will depend on the linkage layout to the rotor head, you want it to tile backwards and forwards to elevator control and side to side to aileron control. On the ones I've built the rotor head servos are usually configured as a "delta wing", V-tail would mean the rotor head is controlled by the Rudder and Elevator stick.

[David Wood]

Thank you , that is very helpful. I'll set it up as you suggest.

I may be probably shortly for more advice!

Cheers
