Has anyone every used this engine with great sucess. I have one that I am thinking about installing on a morris profile and wanted to get some feedback before I cut for the engine. What fuel, props, plugs, rpms, etc. Thanks, BAD ANDY

This is one of the best sport engines made- It has a built in fuel delivery system that is sweet

It is usually used for speed planes (Patriot, Magnum, F-20 etc..) but I have heard good things about fun-flys with these motors-

Run 20/20 fuel (Synthetic), OS-8, and any prop from a 9 x 9 up* The sweet spot on my Lanier F-4 is a 10 x 7 (This is for speed tho.) Dunno RPM's check:

You have the stock muffler or the pipe?

This is by far the best engine I have ever owned- (No I have not has a Jett YET )

One of the really nice things about the YS 2-stroke engines is that they don't require high nitro or oil to run properly. I know several people who have run the .45 on standard sport 10% for several years without a single issue. This engine likes to turn up, and will be happy with anything up to and including an 11X7 if the pipe is set right. They run well on a muffler, OS 60 FSR muffler matches perfectly but I'm sure there are others as well, but they really come alive with a pipe.

Happy flying,

How is the torque of the engine? I will be installing it to do 3d flying. I need good response and great low and midrange power. I was also planning on using the stock muffler. Thanks for your replys.. BAD ANDY

Any .45 that can turn an 11X7 at 13K RPM has very good torque. How it does with the muffler, I honestly can't say. Everyone I know that has one of these engines was too tickled with the pipe to ever consider going back to the muffler.

I'm running the .45 se on a small low winger. I have the Macs black muffler on it and it turns an APC 11X6 in the mid 12k range. Very reliable on 15% Omega fuel and OS#8 plugs.
