No steering and the throttle returns to neutral but then has a mind of its own. could this be due to the chassis vibration, the reciever is wedged firmly between the top deck and the chassis plate so it would recieve alot of vibration. I have a 40Mhz I will try next week.
Do you guys have nay suggestions.
Not wanting to come off as a jerk of smart-ass...but for the love of God, I hope you are not using an AM radio on such a nice car like that. I mean, aside from the RTR, parking-lot bashers, you don't see AM radios that much. With most people going to the 2.4 radios, using a FM radion should not be such a hassle like it use to (finding an open freq)
I sure hope you have a failsafe on that car.
Ok....with that said, check your batteries of the radio and the reciever.
Also not a good idea to use metal servos, especially with an AM radio.
Rubbing metal create low frequency noise that can cause glitching. Some guys use the metal servos only on steering and plastic on throttle. Its a good idea, since the motor is giving off major vibrations. If that's all you have then make sure you'er using plastic servo horn. Make sure all your screws on chassis are on tighten down.
Hope that helps man.....get yourself a FM radio as soon as possible.
