This is an optional Lynx Heli Blade 300 X Low Profile 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, Low Profile main shaft for the 300X. The low profile main shaft is 5mm shorter to help increase agility, and is compatible with both the standard head and the Lynx Heli DFC head, simply adjust the length of the pitch and servo rods!

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.

NOTE: When used with the standard head, the two pitch and three servo rods each need to be shortened by 2.5mm to compensate for the length difference. If using the Lynx DFC head, shorten the three servo rods by 2.5mm.
