Angry Why Is My Mr4 So Glitchy!

I HAVENT RAN MY MR4 IN A FEW MONTHS AND NOW IT DOESNT EVEN RESPOND TO SIMPLE CONTROLS!!! i have a XXL reciever on it and i dotn see how ANYTHING could affect it. the transmitter i used for 2 cars and works fine. the crystal is switched between two cars is fine. i dont believe it is the servo or ESC fault for allt he glitching.

Here is the story:
1) Turn on transmitter (Futaba 3PDF)
2) Turn on mr4
3) Car's wheels are turns to the left and stay that way unless transmitter is moved CLOSER to the antenna, then it move away and back towards the left.
4) Cars acceleration is at a standstill, then accelerates to the max...then brakes HARD!!!

it repeats 3 & 4 until i turn off the car. help please. i just want a simple elctric car to work when my nitro is being fixed.

Sounds to me like you have a bad esc, receiver or radio. Work with those in that order. Also, make sure you have the right crystals in both your transmitter and receiver, that also could be the problem.

Are your transmitter batteries fully charged?

you may have condensation built up on the internals of the receiver and/or speed control or servo, i would suggest you disconnenct these items and leave them in the airing cupboard (a nice warm place!)

leave it for about a day to let the moisture evaporate.

Try swapping the reciever with your nitro car.
