Setting up controls on ERGO 30 CCPM Helo

[rotorz]

CCPM is easy, when you have done it once, this I know does not help though.

The problem you have sounds as if you have set up the travel for your sevo's correctly in the upper half of the cycle but not so in the lower portion,
It is sometimes better to restart your setup proceedure from scratch. Thjere is little difference initially if you use 90 or 120
three or four servo setup.

I would suggest, go back to basics and make sure you reset the channel you are using so all settings are normal, then select your swashplate to 120 ccpm, all travels should be equal.

I like hover at center stick for all throttle settings ( including idle up) so at center stick your control arms would be at centre and all servo control arms at center. If you push up throttle (pitch) all servo's push together and likewise down when you lower the stick.
there are numerous sites online with masses of info about ccpm I put hte address up as soon as I find it.
Happy landings

Hi rotorz,

Can you help me understand what this CCPM/120deg is all about? I've started a new thread "What's CCPM and why a 120deg swashplate - what was wrong with the old design?" here in the BEGINNER'S > Setting Up Questions. It's a genuine question from myself because I honestly don't know, and thought others might benefit it being a completely separate thread.

Thanks ROTORZ. I adjusted the travel for the servo to compensate for the slight differences between servos. I know have level travel from bottom to top. Thanks.
