RC Helicopter Repairing
RC helicopters are considered to be the most difficult RC toy tooperate. It can take hours of concentrated practice to
finally master the art of take off and the landing. It is only natural for a novice flyer to experience crashes now and
then before he can finally do the complicated and more elaborate dips and turn techniques.
A radio controlled helicopter enthusiast should be equipped with the necessary tools to do minor as well as major repairs
on the helicopter after a crash. Screw drivers, needle nose pliers, allen keys, various sizes of hex drivers, multi bladed
hobby knife, scissors, cordless drill, sand paper and glue are the most basic tools.
A broken blade is one of the most common outcomes of RC helicopter crash. If this happens it is necessary to replace the
blade as a blade repaired with the use of glue can result in a vibrating helicopter. For this you would need an allen key
to remove the bolt that holds the blade. Remove the broken blade and replace it with a new one. Tighten the bolt and thats
it, you’re done. Here’s a word of caution though: go easy on tightening the bolt, over tightening could crack your new
blade.
If after a crash the RC helicopter won’t stop from spinning androtating, the trouble could be caused by the imbalance of
the pitch of the rotor blades. This can be easily corrected by making adjustment on the trim of the transmitter. If the
helicopter keeps on spinning to the left, you need to adjust the top rotor blade. Carefully bend the back edge of the
blade to add more pitch. The same thing has to be done if the helicopter spins to the right but this time you need to
adjust the bottom rotor blades. Be careful in bending the blade. A gradual gentle pressure should do it.
If the top rotor blade does not spin after a crash, it could be because the rotor shaft was loosened and the gears are not
interlocking properly. Move the rotor shaft up and down, if there is no play you need to tighten the rotor shaft. To
tighten, use a solid surface to support the base of the rotor shaft and slowly and gently push down the top of the main
gears. Be careful not to tighten too much as the rotor shaft will be stuck and will not spin freely.
