Does anyone have experience with this engine? How does it compare to the ZDZ-80 Super RV-J or DA-85? Any Bore and Stroke info? All I could find was the stroke.

I've got all three of the engines you mentioned, but I haven't run them yet.

Here is the MT80 info:

MT80 Displacement: 80CC
Output: 8+ hp
Weight: 3.85 lbs (1.75 kg)
Bore: 2.16 in (52 mm)
Stroke: 1.49 in (38 mm)
RPM Range: 1200 to 7500
RPM Max: 8500

The HP is just a guess by them don't put any money on it. The engine seems very well made and uses DA85 mufflers and headers so that stuff is readily available.

Thanks for the information Rich. Any plan to testing the 80 cc soon?

I plan to test all three with the same prop within a month or so.

I have committed to purchasing an MT80 as well. My 57 has been running great, just about to start the 3rd season with it (ok 2.5)
I'm looking forward to running it!

How soon do you expect to have it and what plane you plan on powering with it?

Ultimately I would like to install it in my 88 inch Extreme Flight Yak but, it is one of the first versions! I understand that Tomy has since changed the crank and top end and has now got a good running engine. I have ordered some parts from Tomy which I hope are on the way. I have a 120 inch Norseman project ready for an engine so I'll mount it on it and see what it does, then it's going into the Yak! We'll see what happens!
