RCU Forums - FUN Piccolo problems

Hi all!
I bought a FUN piccolo a while back (few years?) after I tried out a Model 110. (The Norvel engine was reaallly hard to start!)
I have a few problems with mine. Here they are. Please help!
The Piccolo in question is a FUN piccolo with the Piccoloboard Plus + onboard reciever. I have also upgraded the swashplate. and bearings.
1. When full throttle is applied, and I run up the tail rotor to turn, the tail rotor quits at full! It won't come back on until the rudder stick is back a neutral. Replaced tail motor, still problematic.
2. I cannot use my favorite Hitec transmitter, but must use my Futaba. I have tried switching the jumper, but it still does not work. Not very important, but annoying.
3. When I was flying, problem 1 occured. It crashed (Hard!) and now the onboard reciever does not work. I think the mixer board works, but the reciever conifrms the signal, then proceeds to send the servos in whichever direction it pleases. A few seconds later, the tail rotor joins in. The main rotor (thankfully!) never does kick in. Does anyone know what I did to it?

Any info would be greatly appreciated!
