Would you provide some performance numbers on the MVVS 2.15 gasser. Whose props at what RPM, please?

I think the weight of the two engines is closer than 8ozs.

ZDZ-40 is 3lbs-6.4ozs. with ignition. Plus prop-hub washer and numerous prop retaining bolts and the muffler. Also the method used to mount/space the engine to the apropriate offset should be considered into the overall weight figure.

MVVS 2.15 is 3lbs-7ozs. with the ignition, prop hub washer and retaining nut. The muffler is additional. A mount for this engine will weigh in at about 4ozs. with bolts.
