Great shaft for DFC, but only for HK550 heli, NOT for HK600, the third bearing under main gear is unused with this and it is too short for HK600... (may be OK for newer Align 600 helis, that have only two bearings, but i can't verify it, cos i don't own one).Just put it on my scale and read 61grams. Compared it to the Flybar version whcih comes out at 73 rams. So Weight reduction is around 12grams when moving to flybarless/DFC. Will do the exercise for the 600 FBL head as well - read weight reduction in the 600 DFC head review.
