I'm sure it's been mentioned, but what's the smallest spur that'll fit the stock setup? Part number would also help.
I was going to get the 8mm Revo spur adaptor from RCMonster but they want $40 for postage because I'm in Australia (have emailed them to see if I can get it cheaper).
EDIT: Would the Ofna 45t spur fit? Part No; 35245.
