I've been sport flying a couple of RC HLGs for nearly 10 years with the JR rec antennas having about half their length coiled around a piece of stiff paper about 3/4" wide by 3" long with slight spacing and a piece of tape in one and the ant wire just wrapped around four fingers and then laid/stuffed in the fuse under the wing saddle in the other. Have been fortunate enough to throw them into some pretty good thermals (15 to 30 min. flts) that have taken them to the (vertical/horizontal) point of having to spin down to regain visual oriention without any perceived lack of control. The antennas are shortened enough to keep the ends inside the rather short tailbooms (1 wood, 1 CF) of these two gliders.

Granted this visual orientation range may not be all that far due to the small (60" span) size of the models but range checks are good and so far there have been no loss of control problems noted.

Have also used the JR base loaded transmitter antennas (~2' long) on glow powered (.40 thru 1.20 size) models (internal/external antennas) with no perceived problems.
