This may be a club of one, as I don't know how many MVVS engines are still used or collected [&o], but here goes.
I took a few shots of my ''Sunday Fun'' 40 sized aircraft between flights this morning.
Powered by my trusty MVVS 49 ''greenhead'' with MVVS quiet silencer. Ultra reliable, can't remember when it last deadsticked.
Regularly used (abused?

) and flown hard for over four years, and still has tremendous compression hot or cold.
I feel the thing will never wear out. I have certainly received my money's worth.
So I don't get lonely, if you have an MVVS engine, post some pics on this thread!
fiery, don't worry!
Here is my contribution and just as you I show my model because she is at least as important as the engine she is carrying.
"Miss Replica Top Flite Taurus". descendante of a family of fifty years ago. After the HB and the OS Max, she is most happy for several years now with the long stroke in her engine room.
Basically she is 'sized' for 0.45 so we can speak about a tight fit with that 10 CCM , see my close up photograph 2.
She did undergo some surgeries to mask her age; fuel pressure controller and Robbe Bordcomputer for datalog of fuel level, temperature, RPM.
Last pictures, "Miss Replica" with some finery, in action, photographs made to investigate the downwash. for which she also is equiped with an airspeed controller and airpeed logging.
