Hi, everyone.
I have Magic 3D from Model Tech and it is my first experience in fun fly.
Can any body give me any suggestions about engine and prop to use on the application as far as options I have : MDS –48, Rossi –45, YS-45 2 stroke engines or OS – 70 4 stroke
Thank you,

The MDS 48 gets my vote. The Rossi and YS are too expensive to jepordize damage in a fun-fly. (I'm more cautious than most)

I would first try to swing an 11x5.

Thank You.
I did forget mentioned that i have all of the engines, so i not need to by them.

The O.S. 70 would be my choice....all those two strokes
are screamers. I think you would get more fun, and
enjoyment out of it with the 4-stroke....

You should put YS-45 on this plane...

Use the OS-70

The YS-45 would tear that thing apart-

I would put the lightest one on the magic, that runs great, with great throttle transition.

Agreed, all your engines will pull the Magic around with authority, but the heavier ones will require quite a bit of lead out back to balance at a lively CG...
