This is an optional Lynx Heli 11 Tooth Mod 1 Helical Motor Pinion Gear, and is intended for use with the Align T-Rex 600E and 700E helicopters. In electric helicopters, the pinion/gear interface is one of the most stressed areas during aggressive flight. Listening to the request of pilots, and with a need to increase tooth wear resistance, Lynx is pleased to offer a special heavy duty edition of the T-Rex Slant Pinion.

Pinion tooth wear is one of the most important contributors to gear stripping. Lynx helical (slant) pinions are manufactured from high grade carbon steel, then undergo a specific thermal treatment process to make them extra strong and wear resistant with no compromise. The durability of Lynx pinions will surprise you!

Lynx offers three different slant pinions 11, 12 and 13 tooth. Used in combination with the 112T slant main gear, this gives gear ratios of 10.18, 9.33 and 8.16, giving you the possibility to use different motor KV or cell counts. When used in the T-Rex 600 and 700 helicopters (12 and 13T respectively), the Lynx HD slant pinion was designed to mesh perfectly with the Lynx main gear (LYX0261) with no adjustment required.

This pinion can also be used with the stock Align main gear (the tooth angle is standard), but due to precise tolerances required the gear mesh may require adjustment. Therefore, when using this combination, Lynx recommends using the Lynx adjustable motor mount:
  • LXY0225 Lynx T-Rex 600E Pro - Adjustable Motor Mount
  • LYX0260 Lynx T-Rex 700E - Adjustable Motor Mount
Tip for best performance: To assure the pinion will not move once installed, Lynx recommends using the following Lynx lock compounds:
  • LYX5266 Omicron Thread Locker: High temperature high strength thread lock for the M4x4 set screw
  • LYX5648 Omicron Retaining Compound: High strength bonding to use between the motor shaft and pinion
Pinion Material: Carbon Steel 38CrMo5 + Thermal Treatment (55 HRC Hardness)
Set Screw: Class 12.9 - DIN 916
Weight: 15g

  • (1) 1-T Pinion Slant Mod 1
  • (1) Set Screw 4x4mm

It does do the job but not the same quality as the original.The gear mesh is not 100% perfect and only one set screw.
