Default four stroke speed

You can only get 10,000 rpm out of this engine. That means you need 14-16 inch of pitch to get decent speed. You can down size the diameter so it will turn that fast. But the problem i have had using ys engines is that once you get up to speed with a sleek low drag jet type plane the engine overrevs and valves float and you get major problems. Either backfire, or break stuff. For speed a two cycle is the only way to go in this size application.

I think if you put it in a WM Dago Red Mustang or maybe even a regular one, you will probably do about 90-100mph in level fight and get 130-140 in a dive. I have a WM super sports 40 which has much more drag than a mustang with retracts and that only has a Saito .72. It was radared at 123 mph in a dive although it did have a good tailwind. That was with a 13-6 prop. With a Saito 100 and probably a 13-8 or 9 prop on a plane like a Mustang you will get good speed.

Default here we go again

Ok lets see. 123 mph on a 6 inch pitch thats 22,000 rpm. On a .72 four stroke and a 13 inch diameter prop. I guess i fly in a different universe that actually obeys the laws of physics.
