Very nice looking motors and Mario Rossi known to be one of the best nitro engines designer in the world.
As motor it self-pretty short strok motor. It should be very high RPM motor ( I am beliving in 45K out of that motors), just one thing I don't personaly understand for 12 MR T01-with parameters stated in their web site strok 13.79 and bore 14.02 the size of the motor come up to 2.13 cc or .13 ci which is over then allowed for IFMAR, ROAR or EFRA rulls for sedan. It ether wrong numbers on their web site or something else, but defenetly doesn't fit to existing rulls (2.11 cc or .12 ci)
here is web link to calculate timing and volums for references http://www.palmarisracing.com/Timing_Calculator.htm
