Default 9C and swash set up on micro heli

Hi

On my micro heli I have set up the servos (CCPM) and arms the best I can BUT the Ail and Pitch are angled in while the Elev is vertical on a SR3 set up.

When changing pitch from full negative to full positive I get a bit of front/back tilt caused by this geometry. I have increased the Endpoints UP/DOWN of the Elev servo (115) and this has helped.

Is there any other adjustment I should try?

Thanks Jeff

Unless you can get all of the pushrods at exactly 90 degrees to the swash plate at neutral and the pushrods 90 degress to the servo arm at neutral, you're going to get some coupling with pitch and roll. It's almost unavoidable.

Thankyou for the reply. I understand and agree.

What is the best way of using the adjustments in the 9C to minimise the coupling effects caused by less than perfect geometry?

First, as mentioned, use the mechanical setups as much as possible. When you have the sticks set for hovering, for example, make sure the swashplate's flat. Now go to full up colletive. Adjust the endpoints to get the swashplate as flat as possible. Do the same for full down collective. this will minimize the effects, but you won't be able to get rid of them entirely.
