Hi

I have a MVVS58cc that did some running in, so far no problems.... Brake in is with a 22x12, later on it will be a 24x10.

It has run 3 liters on a bench, but flying is different.
Starts easy, good trothle response. Have to play with the needles, but will do that in the plane.

It will power a C-ARF Extra 2.30 in the future, but to gain some experience and convidence in the engine i put in on a big Ugly-Stick like plane.

So not much new....
But i think you should try it and find out yourself. ;-)
