Being new to RC I have a question on engine size. I have a plane that I built from balsa that looks similar to a Ugly stick but is a low wing model. noise wheel with a 53 inch wing span.
I think when all is done should weigh in at 3 pounds or less. What would you suggest for an 2 stroke engine size? I am not expecting screaming performance from it just a fun plane to fly and learn some mild manuevers on. The is a 4 channel if that makes any difference. Thanks for the help.

By wing span I would say a bearinged .40 to .46 leaning towards the .40 by the weight you posted. However the engine and electronics will likely bring you up to 4-5 lbs when all is said and done so, I am back to the .46

I agree with Stang. a good .46 should take care of getting that bird in the air.

By size and weight If it is a typical sport plane my ideal recomendation would be a quality .25 to .35 such as the OS AX's.

Also this likely a poor choice in first airplanes if that is what it is especially if you overpower.

I am figureing that the all up weight with engine and electronics to be 3 pounds or less. It will be my first nitro plane as I have been fooling around with electric park flyers. Thanks for any input.

.25 to .35

Mr67Stang

Can you post a picture of the plane? We might be able to identify it and tell you what the manufacturer says belongs in there. But at 3 Lbs or less with engine, servos, battery, etc. then yes, a .25-.35 ought to do it.

i would see if you can get a used .40-.46 bushing engine such as a os .40 la, os .46 la, mangum .40 gp, tt .42, or os .40fp to name a few
if not a .25-35 would be plenty

What is meant by a "bushing" engine? I have a an older O.S. max 45f and an O.S. 25 and a 20 all 2 strokes
I also have a Como S 40.

It means that the engine does not have ball bearings to support the crankshaft. There are simply metal bushings (basically a piece of metal with a hole in it) that support the crankshaft. Many of the bushings engines from OS and other manufacturers are still very good engines and serve many good roles for flying. I have an old OS 40 on my first trainer that has bushings in it, and the plane is 14 years old. and still flying.

Well, if your new enough, then we dont want you spending money on a high powered bearing engine, your gonna drive into the dirt,,,,so lets stay with the bushed OS LA .25-.40 engines, they run like a timex and if you cave in a front end, you wont be out too much money....Rog

Out of your collection, I would go with either the O.S. .25 or the Como .40 (providing they're still in good running condition? )

Thanks for the input. I have bench started all of the 2 strokes and they all run great, None have ever been run into the ground. I still have 3 4 strokes I have yet to try to start but plan to this weekend. Its been a long time and I dont really know why I stopped this hobby. Maybe raising a family who knows. But I am just starting out again and I am really having a blast. Thanks again. I will try to post picture of my low wing Ugly stick? as soon as Iget a chance.
