This is a optional OFNA CNC Delrin 42T Spur Gear, and is intended for use with the OFNA Hyper 9e. This spur gear is half the weight of the stock spur gear, for reduced rotating mass and increased acceleration. This spur has two additional teeth when compared to the stock gear, providing increased bottom end acceleration and a more efficient gear ratio which will help your electric motor to run cooler.

This product was added to our catalog on October 19, 2010.

Update on this Spur gear it is now May 25th... Raced almost every weekend with no issues what so ever.. So for the guy who posted these are no good.. I am sure something got stuck in your spur gear to make it wear that fast..)

After a 5 min practice about 4 teeth were burred, something must have got in between them! I cleaned them up a little with a hobby knife.

After another 8 min of racing the teeth were a melted blob! Back to the steel original.

I have run plastic Spurs before on 1/8th brushless with no problem but this plastic doesn't seem to good.)
