I have a 2.4GHz FrSky transmitter and receiver combo and a 915MHz telemetry module from 3DR. After plugging in the telemetry module, I noticed a twitch in the tail servo on my Tricopter. It twitches every 1 second or so in a little pattern. like T-T-T--T--T-T-T--T... T stands for twitch, wasn't sure how else to represent it.

Removing the antenna from the module fixes the problem, so it's clearly radio interference. Any ideas? Is this a common problem? Maybe problem with the antenna? Or did I just get a bad telemetry module?

Any ideas. Thank You!!!

  • Can't you move antennae further apart
    • The tri is pretty small, about 12inch wide, but while trying to figure this out I dismounted everything and moved the receiver about 12 inches away from the telemetry module, as far away as the cable would allow, it doesn't really help.
