I don't got the right measurement's on the c50s(like spool dia, length etc). I've send hacker usa an email, saying I use it in an airplane lol. Hope they respond.
Got a reply back(actually 5 minute's after I send the email). Can't use the spool of the c-50s, since the spool of the c-50 maxx is unique for this type of motor.
I've asked if it's possible to custom order the spool without the thin part milled down, hope they can/ will do this. No reply as of yet, will let you know how this work's out.
Hmm with a bit of luck that will fit, else mayb a smaller fiegao rotor. Dunno how a longer magnet would affect it's performace. The inside dia of the winding's is 19.50 mm.
Back on the first page, I suggested that the C50 Maxx motor uses a S size rotor, and Serum said that he heard of that too. So, you could try a S rotor from a Feigao.
