What are ECCPM heli's? From what I gather, there are less moving parts. Does this decrease wrench time for wear and tear? Also, are parts just as easy to get?

In particular, I'm looking at the Falcon 50 (non-ECCPM) compared to the Raven 50 (ECCPM).

Thanks

ECCPM electronic cyclic/collective pitch mixing

Its a system in most heli transmitters that uses the servos connected at (typically) 120 degrees on the swashplate to control both cyclic and collective pitch....

Some say it gives better control...

ECCPM mounts the servo pushrods to the swashplate similar to a equalateral triangle. Three servo's allows the swashplate to be tilted.

Your mixing is done electronically, so will need a radio to support the function like 120 degree is one of the most popular. Not all radios supports this, so look specifically when deciding on a radio that does offer support for this set-up.

You will need 3 servos (same model servos) that have the same torque-transit speed so the torque & speed will match each others movement timing. Some reccomend using digital servos, but I have used digitals-non digitals with good results.

You can think of it this way: in mechanical mixing 1 servo controls moving the whole swashplate up/down (collective pitch), 1 servo controls tiliting the swash left and right (cyclic roll), and 1 servo controls tiliting the swash forward/back (cyclic pitch). In general, there's a big collective pitch arm lever upon which are mounted the smaller cyclic levers.

There's a bit more mechanical stuff in mech mixing, but really not enough to worry about. On most helicopters the mech mixing apparatus is very robust.

I'd give eCCPM vs mCCPM a wash for the most part. Depends on the type of flying your doing. Mech mixing may be a bit more beginner friendly and I think you can get away with cheaper servos.
