The official 600 stretch mod thread - Page 38

I've just received the last of the parts necessary to do a Direct Drive electric tail. I'll be using a 4250 320 KV motor running on 8S which is what the main motor uses. This will allow me to stretch the 550 to 700 without any belt drive fuss.

You can use RJX .50 grips on an Align 550/600 hub if you use the RJX feathering shaft. These are 14mm grips so you can fit up to 700mm blades with no problems (the RJX .50 grips are just the .90 grips with different screw holes for the arms)

HK has the parts cheap (e.g $18 for the grips vs $30 from heli flight center) but they are hard to find on their site. You can find them easily by searching for the RJX part number on HK. To use the grips you need the blade grips, arms, blade grip bolts feathering shaft and thrust bearings (the bearings are bigger so they're not compatible with Align bearings.
