So I'm going through my father's old plane equipment (he doesnt build kits anymore). I find a teasure trove of engines, mostly OS Max and Super Tigres... and this big boy.

He doesnt remember what it is, it had to be purchased in the late 90s. I assume it's a clone and I don't recognize the logo. All we can remember is that it was going to be mounted in his bi-plane to give it a more scale look.

It's a big sucker, it's got a 12 stamped on one side and the M logo on the other. See the picture below.
Can anyone Identify the make and model of this sucker?
I appreciate the help

Moki 1.2?

I think it is a Mark 1.2 as above but the Moki was renamed Mark 1.2 in the USA for some business reason.

Good engine. If it is like the Moki's I have used it will not like high nitro fuels. 5% is cool.

Its a MVVS .77. The 12 is for 12cc. which equals .77. They are pretty good engine made in the Czech.

Thanks all. This thing was driving my dad and I nuts.
