You know I am sure velcro does reduce vibration, I don,t see how it could not but anyway using the hooks and loops has become a standard for me and I certainly don,t feel I am any worse off. I actually got into using it before 2.4 in my pylon days and I could not see any higher damage rate than with the foam. Actually what I have noticed is that the 2.4 rx's seem to be far more durable in crashs than the 72 units, go figure.

As for the range in the power down mode, don,t know I don,t bother rolling more than about fifty paces.

I have many airplanes with the antenna leader wire running with a 180 'U' turn but no full loops and I am totally comfortable with that. Have not found an airplane yet that I cannot stuff a 6 or 7 channel 2.4 in, in fact I got an awful lot of the sevens but only seven of the six channels.

I also am working on my next Ukie and it will have the Hitec six's on board for throttle and stooge release. This instead of my old over the wire electronic system. Guess I won,t have to do range checks on those since the airplane can never be more than sixty feet away

Are all three of your Optic Six's the same model or is the 2.4 the low voltage six cell instead of the eight cell version? I know that for me to buddy box my two Auroras with the Optic Six that the Optic must be the six cell low voltage version.
