Yes JSR, as far as I'm aware they are just E-maxx turnbuckles. Nothing special. When I get home I'll check length on them just to make sure, I think the front and rear turnbuckles are different lengths, I think you need the longer ones for the Exarms.

On another note my motor just turned up. Got some plugs soldered just waiting to get home from my parents to get it mounted. Looks pretty trick!
