| Hi again...
To check electric continuity, you must put your probes on metallic parts, not on carbon ones.
This is why I advised to to check between the engine and the ball-bearing holder.
If you check between the engine and the cabon fin your reading is likely to be unstable, as you may or may not touch a carbon fiber which may or may not be connected to the fibers touching a metallic part , or just resin.
If you touch mettalic parts on the heli, the reading should always be 0 (full continuity) or very very close to 0...
If it is not the case, try to find where you have to sand the carbon parts by testing different metallic parts to find where is the bad connection.
You mentionned your heli is nose heavy, so the receiver should be in placed in the back, furthermore, if you place it where it should be, this is the place where it is most likely to survive in case of a major crash.
My antenna wire is going from near the bottom part of the landing skid (as advised on the documentation) and fixed by an elastic wire to the middle of the lower part of the vertical fin. It is a good idea not to have it parallel to the tail boom, and as far as possible from the frames and the canopy specially if you have the carbon one (as I have).
Having the wire going from the receiver directly to the upper part of the fin will give you bad result. (in certain positions it will be completely shielded by the tail boom).
The elastic wire I use is not a simple rubber elastic, but comes from my wife's sewing kit. Although it is elastic, it includes textile, which make it unlikely to break like a rubber elastic. I used also the supplied plastic guide to add some rigidity to the wire.
