After several years of experience on previous planes, I decided to get a new plane, one capable of 3d. I have decided on a Ucando (Great Planes), model size 46 or 61. I have several questions posted below regarding the model capabilities and engines. When answering, please keep in mind I want good vertical performance and will be purchasing an OS engine.

First, what would the advantages or disadvantages be between the 46 and 61 size model? Would one of the perform better in the air?

Should I ideally use a two stroke or four stroke motor?

What size motor would I use on a 46? 2-stroke size 55? Four stroke size?

What size motor would I use on a 61? 2 stroke size? Four stroke size?



Thanks,

Michael

I don't have any experience with those planes so can't really comment on them. As to the 2-stroke/4-stoke decision, I think it's entirely personal. Both will fly the plane quite well. Personally, I own several examples of each. My suggestion is to try one you haven't yet experienced. There's nothing wrong with expanding your modeling expertise, right?

On the .46 the .55 AX will give you awesome performance.

On the .60 while you can go with a 4 stroker, I would be going with a 2 stroke .75, such as an inexpensive Tower Hobbies .75.

The T.H. .75 gives you the equivalent pull of say a .91 four stroke but at a reduced weight.

A lot of people seem to recommend 4 strokers on planes larger than .60, up to 1.40, then gas beyond that.
