I have a nitro P51 Mustang with an Evolution Motor (idk what size it just says Evolution & has an: a stamped in casing.) I’ve got a JR R700 7ch reciever (Batt., Aux1, Aux 2, Gear, Rudd, Elev, Aile, Thro) running off a JR Propo 4N600 4.8V 600mah battery. 5 Servos are a JR NES-537 and 1 servo is a Command dual B.B. servo CS-67 (that runs my 2 flaps on my receivers gear port) My transmitter is a JR XF421 EX running a XF-421EX 8N-600 9.6V battery. I got the plane used. Plane probably sat for a bit. Engine runs great. I replaced all fuel lines etc.
MY ISSUE:
When outside & I turn the transmitter on first then the receiver with fully charged batteries & semi drained batteries, I get a lot of servo twitching & chatter. Mainly my rudder, ailerons, flaps. I have tried unplugging 1 at a time but it still exists until all 3 are unplugged. I have tried seperating my transmitter from my receiver (various distances & it still happens.) I have tried separating my power wire & antenna. I have even disconnected the servo arms but the servo still twitches & chatters. This drains my receiver battery in approx 10-15 minutes. Crystals seem ok since only prob. W a few servos. Are the servos bad, receiver bad?
Im new to RC planes so please help!
Also anyone know the size my motor is?
I can’t fly her till I get the servos to calm so this is the hold up!
