Basic rule is keep the antennae straight leading out along the fuselage,inside it or to the tip of the fin,do not under any circumstances cut the end off,believe me I have seen it done because the newcomer considered it too long.
If the antennae gets damaged then send back to the manufacturers for replacement and tuning.
Take particular care with model helicopters and dont chop off your own aerial ! easily done,fit the antennae into a plastic tube attached to the skid of the helicopter.
Should you get problems such as with the high aspect ratio glider wing with carbon fibre fittings or spars then consider fitting ferrite rings to the first couple of inches of the aerial,this normally cures any problems and will blanket any unwelcome signal.
Above all do not leave the aerial coiled up with the receiver as one scale modeller did with his brand new twin which crashed on take off.
Best to do a range check on new unproven models which would have showed up the above silly and expensive mistake.
