Thanx Rob. Me too.
I swapped out the Servonaut S20 I was using for the swing, installed a Sabertooth 2x12 & used the 2nd motor controller for the screener. Not knowing right off what rpm would be suitable for the screener, I started with a higher rpm gh motor & played with the tx's epa. The current gh motor is 40 rpm, still a little on the fast side @100%, got it dialed back to 60%.
I'm having trouble with the Sabertooth remembering its previous calibrations for the swing speed (EPA) after turning the model off/on. I could go back to the Servonaut, and now with this 40rpm screener motor, use a battle switch to turn on/off.
