| Digitals 120 CCPM and speedI saw a guy use just standard super servos (0.16 sec/60deg), and it was just fine. Yeah the torque vs. input is not linear, but so what.
In any 120 deg CCPM configuration, there will be collective mixing with heavy elevator use.
Here's a bench test of your setup:
1)pump the elevator slowly
- the collective level should not change at all
2)now pump elevator as fast as you can
- the swash will rise/fall each time
This is caused because the two front servos have a shorter path than the rear one. This means that they will get to the full forward/backward position before the rear servo catches up. This is unavoidable unless you use 140 deg CCPM, which just pushes those swash connection points forward, preventing this situation. Naturally, the faster the servos are in general, the less this problem will come out.
I have seen Fury's rung-out a lot, and if this is a problem with any servo, I have not heard about it. Most people don't pump the elevator back and forth enough to cause any collective interaction caused by inadequite speed.
PS. I hope to see y'all at the FF at MAC's in Andersonville/Americus, GA this month. |
