I have been using the Powerbox Champion in my 40 Percent plane for 1 year now. Here is the set up.
-Rudder 2 servos, Elevator 2 Servos Powerbused.
-6 Aileron Servos standard set up into the Powerbox.
All has been good up until last week. When I went to taxi out of the starting stands I had no rudder. I also had no Elevator but the Ailerons worked. I shut the motor down and re powered the plane. Everything worked fine on the power up.
Yesterday my Elevators seemed almost stripped. Notchity. I did not fly (I will get into this later) but today they are fine.
Something is going on. Any ideas. I checked all connections and it is fine. There has been multiple flights on this set up and this Powerbox with the hole system powerbussed in another plane before this one.
