I have read alot about removing the crip cap to increase range of car. I have a 45 MHZ Bit char that has the crip cap on PCB. I removed it and the range seem pretty good. The problem is that I get interference when my other 49 Mhz car is in the way. Once I remove the 49 Mhz car, the problem goes away. I have read that the crip cap on the PCB is suppose to help with Interference. IS this true. I need one of you experts to help me out.
