Hi There
I've just about finished rebuilding the Observer after a radio glitch/failure related crash. I've become a bit parnoid after the crash and reading all the posts about radio glitches on Gassers.

Unfortunately as we fly on 40Mhz a Deans or Revolution base loaded antena doesn't appear to be an option.

Please see attached photo which shows where I am considering positioning the Rx and Antena. The Rx is on the back of the rear battery tray and the antena runs slightly forward and then back down rear facing plastic tube ... this is zip tied to the RH boom support. The Rx battery is posioned on the front battery tray.

I've done a range check and got 150metres (450ft ) plus on the ground with the Tx aerial down, which seems pretty good.

Any comments or suggestions regarding the antena would be very much appreciated.

Thanks for reading

Brian

Your range checks sound more than adequate, however it's what happens when you get off the deck. It is also unfortunate on the unavailability of a whip antenna that you could mount forward of the ignition noise sources. Personally, I don't see anything wrong with your location or installation, however I am still new to gasser's as well. My slant on the subject would be to go in small steps and see what happens and, be prepared to take immediate action should you start taking hits. I am confident that, as popular as the Intrepid is world-wide that either your installation will work or someone in this forum will be able to advise you.

I have my antennas on both of my observers mounted off a strongbox which is located on the radio tray. You can see them in my gallery. I have never had any radio problems set up this way.

Here is how mine was setup:-

I would recomend you earth the boom to the engine to eliminate static from the belt, as I found more problems were to do with this than the engine.

Hope this helps,
Evan

Hi Guys
I really appreciate the feedback, photo's and links.

Looks like earthing the boom and shielding the ht lead is the way to go .. I am off to buy a testing gizmo ...
