RE: Rossi .53 for speed??
Awesome Julian! This could be the ultimate motor for 40 sized speed machines and deltas. A bit of lathe work can bring the outside head dimensions down to size if needed , but I'd like the extra cooling VS speed. Three bills is not out of line for a great engine & pipe setup. Good used OS ducted fan motors/parts are getting hard too find and pricey. Let us know the Rossi runs!
