hi....

I would like to know what will be better of it. I am thinking in a 1.80 metres airplane with 25 cc gas engine approximately.....

Suggestions????

Thanks.....

Well it depends on your flying style... your question is too vague.

Personally I think it will be tough to find good performance on both power and wingloading on that size plane with a gas engine. Don't get me wrong but you are far better to go out up a size on plane and a size or 3 on engine.

yes...... it's true......i have not spoken about style......

i want fly 3D......everybody say that fly one gas-airplane is "the best", and i would like to feel this sensation

thanks

well if you want gas, small plane, and 3d I would say one of the following

UL Giles with a Brillelli 40GT or Brison 2.4 25cc isn't going to cut it.

ok..... i understand.....
but for you...... what size will be the most appropriate for my first gas's airplane?

Well the plane I suggested is like a big foamy.. lands well and will do great 3d

You want something light with a 76" wingspan plus. Gas engines are heavier than glow and not as powerful size for size so its important not to put a heavy gas engine on a small plane or it will be a flying brick.

Here is a thread about the plane I am talking about
