I'm a newbie on RC plane with a piper cub falling on my lap. A month has passed and it is still on the ground. All airborn gears are there but would someone with enough knowleges on electrical stuffs to tell me what is wrong:

- Four Hitec HS-311 servos.
- Cirrus MRX-4 Mk.II 4Ch FM 72MHz receiver (battery is excell.) (http://www.hobbypeople.net/gallery/443534.asp)
- JR F400 4Ch FM 72MHz radio with both TX & RX crystals 72.850 (battery is excell.).

PROBLEM: With all power on radio and receiver didn't communicate what soever!!!!!! [sm=angry_smile.gif] And it was spooky enough that with the power left on for a while then suddenly all the servos acted up at the same time by themselves (scared the heg out of my wife at night!).

NOTE: TX & RX came with the JR F400 radio (used) as a seperate pakage, not originally with the airplane. I bought it as thought that any 4Ch FM 72MHz radio would work with the Cirrus receiver (wouldn't it?).

Please help or someone will come to my house to perform "exorcism" on the piper!

Thanks!
