Aloha
Have a couple of freedoms. They both wound up with electronics problems after awhile. I converted them to 72 mhz (from stock 27mhz). Took out the circuit board from the plane cut off all the componets I could then replaced the servos with standard 3 wire servos. drilled a couple holes in the original circuit board and tywraped a 72mhz reciever and then tywraped a speed control. It all fits back in and my problems are few now. Many great flights.
Have Fun
