Lars,
PM me your address and I'll put a piece in the post.
I bought some to see if it would be feasible to wind my 36t inrunner with. It wasn't. Inrunners are more tricky to wind than outrunners. They usually require greater manipulation of the wire so, work hardening of the copper is more of an issue. It may be fine to use for your RV 120, the bend radii for this are greater etc.... It would be wise to get a feel for the wire before ordering, though.
With regard to the inrunner design, I have one in construction. The case and rotor are made, the stator lamination stack is made. I'll have more time to work on it again in February.
