No lose connections at all in that system, nothing is ever intermittent with it. Receiver is mounted right behind the antenna on the helmet. Having it on the ground made a big difference at 900 MHZ, not so much at 2.4 ghz. But I did not get a chance to do much experimenting at 2.4... I think my solution will be to put a ground plane on the antenna, this will be easy, an aluminum plate behind the patch twice as big. I can attach some wires to the ground of the patch and screw them to the aluminum ground plane. With that size, the head mount will have to go, but I can put it on a tripod.
The Liftmeister looks like a SWEET airplane
Big enough to put a G26 reliable gas engine on it ! And a bunch of gas and gear inside. I think I could make that fly for 2 hours easy with the G26. If my current large plane ever gets crashed, I will be getting a liftmeister. The rascal looks kind of fragile and small for my needs. Doing long range FPV, planes eventually get into dives, etc, I need something that will stay together in a nasty high speed pullout.
