I'd be more concerned about the radio interference. It's not very common when using a dual conversion receiver with proper antenna routing and a radio system that is in good running order.

If proper frequency control is used at your field to prevent simultaneous transmission, and you're sure you weren't being "hit" by another pilot, you probably ought to give your whole radio system a good, thorough once-over:

-cycle transmitter and receiver batteries to make certain they are delivering rated current capacity (Mah)
-range check transmitter and receiver thoroughly
-inspect receiver antenna for damage, make sure it's routed away from control rods and servo wiring
-inspect servos and control rods to assure there is no metal-to-metal contact points to cause RF noise

For as much hoopla as the new 2.4Ghz radio systems are getting, the truth of the matter is that 72Mhz radio systems today are really, really reliable as long as they're installed and maintained correctly and clubs follow simple frequency control measures to prevent channel conflicts.

If your plane was taking "radio hits" and nobody was on another transmitter with the same channel, something is wrong and needs to be sorted out before you fly again.
