OK Crowd,
I am Building a Midwest Aerostar 40 trainer and at the point of Engine installation. I'm going to use a .45/.46 2 stroke.
Which brand do you all recommend?
Should I go 4 Stroke?
Consider the can open.

What your preferance? There are many good choices. What's your budget like? Engines in that displacement range start at about $80 and go up.
Stay within the recommended power range and try an OS, Supter Tiger, Magnum or one of the many others. What's prevalent at the local model field? Go from there!!!
Good luck and Have Fun !!! [&:]

Many good engines. Choose the one you like and can afford. Irvine, OS, TT and Magnum make great engines. I don't care for the 4 strokes as much as 2 strokes. Use the one you like best. There is no best engine. Most of them are pretty good.

Take a good look at the TT line of engines.....many feel they are the best bang for the buck!

Webra SPEED 50

I put the Falcon Trading ARF version together with a well broken in OS 46 for folks coming to the field that want to try flying (on the buddy box). To keep the speed down I use a 12.25 x 3.75 APC prop. You can take off and go straight up if needed. It will even hover, but falls too easy due to small control surfaces. Handles different speed ranges without trim changes.

All the above just to say you could fly this plane on anything from a OS 40 LA up to a Saito 72 four stoke and it will do you a fine job.

Stick with the the OS 46.Dont try to save a few bucks on a door stop engine.The O.S. will not let you down and save a bunch of hassels at the field when your trying to get going at the field.

The new OS .47 AX should be awesome.

I have a .46FX in my Aerostar with a 10x6 prop. It's worked for me (had a 10x7 prop for the first half of the season, it became much easier to land with the 10x6).

HA! All engiens have plenty of hassels to offer along the line. OS is no different.

Engines are like anything in life treat them right and they do you right.Run a good fuel,the right prop and dont run them lean they wont do you wrong.Most of the guys ive seen here with consant engine problems dont do any of the above. You gotta admit they are a hell of alot better than 10 years ago.

Two stroke; Evolution 46, OS 46 AX (or even a 46LA if money's tight), Thunder Tiger 46 PRO.

If you go to four strokes you'll probably never want another two stroke.
OS 70 Surpass, Saito 72 (?) on the high end of power, or OS 52, Thunder Tiger 54, Magnum 52.
