Default Airtronics MX3 out of range.

ive been having problems with my radio lately,

im running an airtronics mx3 75mhz on ch77 with airtronics 94102 and hitec 625 servos, and on both my nitro and my electric, once it goes past 15-20 meters it loses complete control of the car. im pretty sure its not glitching or anything like that, the transmitter antenna is a little bit harder to extend and retract, but i think thats from nitro residue. The only damage i notice on the whole electronics setup is a small nick on the reciever wire insulation thats less than 1 mm long, and definitely not cut into the wire itself.

i have installed a venom 1100mah rx pack from 4 aa's, but that should be whats causing problems, because i dont use the rx pack on the electric. could i have damaged the rx by plugging the rx pack into channel 3 instead of the batt slot?

please help me guys, i have no idea what could be happening.

If I guess I'd say it's something wrong with your reciver, if you have an ability to borrow an other RX and test you would get an answer

Default yep!!!

Pull out the battery box and stretch your springs a little also remove your crystal and check the pins to make sure they are getting good contact and make sure it's all the way in (radio and reciever)and then the antenna contact. and the battery pack in the car.If this fails to help you then I would open the reciever and check for cuts or breaks in the antenna wire all the way to where its soderd. assuming that the length of the reciever antenna wire has not been alterd and if that still dosen;t help then open the radio and check the wire that goes to the antenna. and one more thing make sure the antenna wire is not touching the other wires to the reciever ,battery and servos I hope this helps you.

the reciever wire travels thru the same hole in the reciever box of the ntc3 to get to the antenna tube. im pretty the wires used to touch and there werent any problems?

my antenna was bitten by my cat at the end and she took less than a mm off. but even after that i think it worked fine.

Did you check every thing else? and I would just replace your antenna wire there cheap but make sure you get the one it calls for
