Hi, I've had my redcat tornado BB for about a week now, and its my first real rc car. When i bought it, it was raining hard, so they sold me some balloons to put around my receiver. When i had the balloon on, the servos would switch all the time. The steering servo would push all the way to the right, and the the steering wheel on the control would control the thorttle of the car. What causes this? and how can it be avoided? It hasn't happened yet with the balloon off though.

My car and control run at 27.145MHz, Seeing as how nearly half of the crappy rc cars come in this frequency, or 49MHz, would it be worth it to get off of it?

Thanks for the help!
