I have an early model 450X, the gray plastic frame, that I purchased used. I have noticed on spool down the swash plate wobbles very slightly. Since I got such a great deal on the heli I would like to invest some cash and rebuild the head and replace the main shaft, feathering shaft, rubber doughnuts etc. I usually order parts from TechModel Products http://www.techmodelproducts.com/ and was wondering what parts I need to do a rebuild of the head. I dont see any gray parts, just black ones and was wondering if all the 450 parts were are interchangable. If someone could list the part numbers that would be ducky. Thanks in advance!
