servo saver help
 

didnt want to hijack tempest's thread so started one of my own

so got a cheap MG servo for less than £3 delivered, just spent about 45 minutes trying to count the splines, finally got a consistent 21 splines for 3 counts and decided that must be it :cry:

with that count, anybody got any ideas on which servo saver to go for? I know that a FTX blaze saver doesnt fit, and also now know that the standard losi saver is hex:blush:

and not one to waste a thread(pun intended) what size screws for metal parts on mini-t, i was guessing M2 but dont want to waste money if im wrong again

thanks for any help
