Hi guys

Has anyone had radio iterference problems due to the installation of a Tam Gear Failsafe unit?

I have just installed a second one of these units in a SM F5. During initial range checks I found that various flying surfaces on the jet were jittering. I changed the antenna position, but still the jitters. Then I changed the receiver, but still the jitters. Finally I started unplugging various servo leads from the receiver. The moment I unplugged the retract servo all the jitters stopped. I then plugged the retracts servo back in without the Gear Failsafe unit (being on a y-lead), and no jitters. The moment I plug the Y-lead with the Gear Failsafe unit in, the jitters started again.

I was about to install another Gear Failsafe unit in the F5 when I remembered that I had similar jitter problems on my SM F15 a while back. In this case moving the antenna had sorted the jitters out and I have been flying the jet without any problems. I decided to put the antenna on the F15 back to it's original position, and back came the jitters on the elevators. You guessed it ......... as soon as I took the Gear Failsafe unit out of the receiver on the F15, the jitters stopped.

Please let me know if I am doing something wrong as the Gear Failsafe unit is realy a great idea. What's more I bought a few of them to eventually install on all my jets ...........

Cheers
