This is an optional Lynx Heli Blade 300 X Standard Length Carbon Steel Ultra Main Shaft Set. Lynx knows that the 300X is a high performance machine, and high performance heli's require a serious no compromise main shaft. So Lynx stepped up to the plate and produced a Carbon Steel, special edition main shaft for the 300X.

By combining Carbon Steel with a dedicated thermal treatment, Lynx achieved the strength increase they were after. The diameter of the Jesus holes was revised to provide a precise fit with the M2 Jesus screw, while the main shaft was revised by removing the Set Screw collar socket to increase the strength and durability of the main shaft. This main shaft is an ideal upgrade for any 300X, but is highly recommended for high power set-ups.


  • Direct replacement upgrade for the standard 300 X main shaft
  • Increased strength
  • Increased tolerance & precision to help eliminate any vibration
  • Precision Jesus Screw holes increase shaft resistance and reduce play
  • Revised design without main shaft collar socket for increased shaft resistance
