Storm 430 Rotor head parts
 

I have a storm 430, which is supposed to be a clone of a trex 450se v2. Every part I have bought for a trex 450se v2 has fit so far, but now im stumped. I bought a trex 450se v2 blade grip and shaft set on ebay, and the shaft is larger in diameter and won't go thru the o ring cushions. There are alot more parts to this set also, like disc bearings that go between the grip and the head. I can't find any stock plastic blade grips. Even helipal doesn't have em in their parts list.
Does anyone know what other heli has the same plastic blade grips ?
Im afraid to buy a whole trex 450se v2 rotorhead on ebay in fear the main shaft will be larger or something. I'd like to put a whole CNC 450se v2 rotorhead on it if they fit. Dennis
