HELP!? RC radio control plane crystal problems? The transmitter no longer controls the plane?

I used to fly a Parkzone Stryker C radio control airplane. I put the electronics ( receiver, servos, etc.) into a nitro plane and the plane has been flying great for nearly 2 seasons. Last week a gust of wind caused me to have a fairly rough crash landing... i guess thats what i deserve for flying just before a storm. Anyways, I brought the plane home only to find that the transmitter no longer controlled the reciever. The parkzone transmitter has fully charged batteries and is in good shape. The reciever also has fully charged batteries and the servos still jitter like normal when the reciever is turned on. When both the reciever and transmitter are on, however, the transmitter doesn't control the servos. I can toggle the joysticks all I want and still get no response. Occasionally, however, the servos seem like they are trying to move in the direction that the transmitter is directing them to - they jitter in the direction of directed motion for a few seconds before going dead once again. So based on my tests, i have concluded that both the transmitter and reciever are getting power, and once in a while a weak signal gets through. I was thinking that maybe the hard landing caused the crystals to go bad? Is this a possibility? Any other ideas? any help would be greatly appreciated.HELP!? RC radio control plane crystal problems?

You may have cracked the circuit board inside the receiver. Open the case and inspect the board closely, look for hairline cracks in the board.


Swapping the crystals for a known good set will tell you if you've damaged them but it is unlikely.
