Ok, here's one I really can't figure out.

I live near a forest, which obviously has a lot of trees. There are some cool jumps back there and I wanted to drive my RC10GT there. I took it out and when I turned on the electronics and the TX, the steering servo was fine but the throttle servo went to full brake and started glitching like crazy. I thought my throttle servo was fried so I started to head back to my apartment. I decided to try it in the open parking lot right outside my apartment and it was perfectly fine. No glitching or anything.

Are all the trees causing interference? I don't see how that's possible because I'm running a 2.4 GHZ Airtronics system... I'm stumped. any ideas?
