Save money?- No -
Save conflict of servos -which results in high battry drain and worse yet - servo heating !
The present servo setups of multiples , hard coupled to one output , is a risky setup - If you can't do it perfectly - Don't do it.
The digital / analog combo -or using "loose " center digital servos, gives the servos a chance to "resolve" as intended.
Ideally, there would never be more than one servo -to any given output.
I am doing a 50% bipe at the moment and the kit mfgr recommends a box full of servos -
We will reduce this setup by half.
