RE: Radio problem or interference?
I have a bunch of HiTec RX's...
All function w/o problems.
HiTec includes a little anti-vibration cover with the RX's to cover the crystals.
Using these is a must.
The use of a HiTec RX radio system is not the problem.
CherokeeFlyer you are getting radio interference.
Which model RX are you using?
Have you tried changing to another channel?
