CNC DerlinMain Gear 115T&14T Steel Pinion:TREX700N Overview
The main gear stripping problem in T-REX 700 is a serious issue that annoys most flyers as they have to change main gears every couple flights. While most other 90-size helicopters use 1.0M main gears, this T-REX 700 is designed to use 0.7M main gears. Lower module main gears have smaller tooth surface than larger module main gears. MicroHeli is the first company to release the 1M CNC main gear and 1M steel pinion for T-REX 700 to reduce the main gear stripping problem. Precision CNC Main Gear is much stronger than plastic main gear. The CNC main gears are true and unwobble. Moreover, the new CNC main gear is produced with better material than stock main gear. This material will make the gear stronger and therefore it is not easy to wobble or strip. It is produced by CNC machines so it is absolutely true and round.
-The main gear is NOT a drop in replacement gear for stock T-REX 700 which has 164T.
-Same gear ratio as stock T-REX 700N 8.21:1
-The new CNC delrin main gear and pinion has same diameter as stock ones.
