Finally got my new MVVS on the bench today first off it is fitted with the smaller carb for the
40 and 49 (reason after break in it goes to diesel) think its 7mm intake. FAI fuel stock mvvs
plug 12x6 wood zinger prop it roared to life after 2 flips a real kitten to start no bad habits
at the end of the first tank 10300-10400 on the small carb muffler in cowl mvvs, this acted more
like a 4 stroke really nice> I am an irvine fanatic 1 46 and 4 53s so far this has swayed me
final home VMAR dornier DO-27

I had a MVVS 77--They are a darn good motor and replacement parts are darn reasonable too!! Good luck and good flying!!

The .61 MVVS is a beautiful engine. Idles like an electric, and you'd be absolutely astounded at the log-turning grunt this motor is capable of. Lord knows what happens on diesel.

My only complaint about MVVS? I just can't afford to buy all of them!
