10 Radio Glitch Fixes
 
1) Receiver Location. The location of your receiver is very important. Try to mount it so it is the highest control in the car. With todays receivers, weight is of little matter. I would rather have a high ounce over cg than a glich at the wrong moment. 
  
2) Locate the receiver as close to the antenna mast as possable. If necessary relocate the mast. The antenna kit from Associated works very well and they give you an extra long mast as well. 
  
3) Don't let the antenna wire touch the chassis. With all the graphite parts used today, this is most important. Graphite is a good conductor. It will pickup pulses from the motor/ESC/battery and interfere with the radio signal. 
  
4) Drill a hole in the side of the antenna mast to keep the wire off the chassis. See above. 
  
5) Don't drape wires from the motor/ESC/batteries over the receiver or antenna wire. 
  
6) Try two layers of servo tape to further insulate the receiver from the chassis. See #3. 
  
7) Inspect the receiver antenna wire for breaks. 
  
8) Be sure that the antenna is the correct length. 
  
9) Always use fresh batteries in the transmitter. 
  
10) Check to be sure the transmitter antenna is tightly screwed into the transmitters body.
