after flying a few different types of micro helis, including the other junk, i noticed a whining sound coming from the gear case. To me its like scratching a blackboard! Gears should be lubricated at all times. I would think that lubrication on these tiny plastic gears would improve smooth operation and in  turn promote longer flight times. WD40 unfortunatly does not work. I found that it makes the small gear on the motors slip. So, i found a product that works perfectly. Out in my girlfriend Micheles garage , who also flys, and pretty damn well, i found a lubricant made by Dupont called Teflon Multi-use Lubricant. It sets up dry and only a drop is needed per motor. I actually sprayed some in a small bottle cap and applied the lubricant with a toothpick. Right after applying a drop or 2 turn on heli and let gears spin for a good ten seconds.All of you micro heli freaks will thank me for this one! enjoy your flying. kevinwelder
