How can I get rid of some interaction on my CCPM heli?
CCPM can work very well if you use quality digital servos. With or without digital servos, all CCPM systems may have slight changes as you move through the collective. This is simply because not all servos are identical and so they sometimes move slightly different (centering and travel). Today, most will work fine with no adjustment but if you really want to tune the CCPM system perfectly I’ve found the following works very well without a ton of new mixes having to be conjured up. Start by leveling the swash at your zero pitch mark- IN STUNT MODE! I’m assuming for this discussion a +/-10 degree pitch range for 3D helis. Move the servo wheels on the servo output to where they are 90 degrees to the pushrods so that you will have equal travel when you go positive pitch as you will when you give negative pitch (the output or distance the pushrod will travel is the same amount both ways). Once you have this set on all 3 servos, fine tune with SUB TRIM in your radio on each channel to make
