RE: SPA Rules question- Why aren't retracts allowed?
I know this isn't retract related, but does anyone have/make/made a list of approved motors? From .45-.61 2-strokes and .70-.91 4-strokes? I still have a Hanno and YS SE & RE .61's around here. But thinking of a .45 size motor if I can get the Trouble Maker light enough.
