Hey there... I am currently stationed in Balad Iraq... I fly my T-Rex in our HAS (hardened concrete hangar). When I fly it outside I take occasional hits, who knows what the military has going on out here to cause interference. When in the HAS, I take a hit at about 5 feet in the air. These hits are constant, and just cause a quick drop in head speed. I have tried a few things to eliminate this. I switched to a rubber ducky antenna,with no change. I am wondering if there is any instances of the signals bouncing off the concrete causing a glitch? I know the military has some jamming equipment, but the fact this occurs only at a 5 foot hover makes me think it is something I am causing. I am using an Airtronics RD6000, rubber ducky antenna, hi tech micro O5S reciever, with no antenna modifications. I will try to post a pic of the routing of the antenna on the bird, but it looks about the same as most pics on the net. Anyone have any ideas on what I could do to help this problem?
Thanks
Greg

You have a ferrite ring in it? I imagine there is all KINDS of interference on a military base.

No Debian Dog, I never thought about the ferrite ring. I kind of assumed it was the location of the receiver antenna or the 5 foot height being right inline with the tip of my TX antenna. Thats why I went with the ducky. If it were stray interference, I thought it would be at any altitude. Figures too, I just made an order from Helidirect this AM. I may have to e-mail them and see if they can add one to my order. I guess it cant hurt to try it..
Thanks

No electrics are PRONE to glitching. I lost (totaled) my Trex450 due to a lock out right in my front yard. The smaller helis are worse because everything is packed so close together.

Keep your head down over there too. Me <- ex 1st Cav

Iside all that concrete is a steel mesh for stregth. Flying in the hanger is like flying beside a giant chain link fence and it's reflecting the signal back to the helo out of time/ phase with the original signal. This causes your glitch. Same reason you don't fly at a base ball field with the big parabolic fence designed to keep foul balls fromgoing into the stands, or in a tennis court with 20 foot high fences... It's pretty easy to figure out if you think about it.

I've flown my helo's in the hanger bay of an aircraft carrier while out on deployments with no issues... also flown airplanes and cars off the flight deck during down time.... no issues with interference and we had so huge high power transmitters on the carrier...

Evan, I figured the steel would be causing some of the problem, But how were you able to fly inside a carrier without taking the devastating hits?

No hit's never had a problem.... I was flying .46 size nitro helos with full range radio gear though....

After all the wierd places I've flown in really high RF areas the biggest problem is still the guy that turns on not checking th frequency board...

Those are nasty. I have seen a heli totaled because of that... Not much to be salvaged from the heli. And even when it was on the ground he couldn't turn it off!
