Good day all,
So i want to know would an 30cc engine with 2hp be enough to fly an aircraft of 20 - 25kg ? Please need some help here.
Thanks in advance.

Hi Johan,
The answer is dependent on the airframe you choose. Based on what you have said though, this is marginal power for even a powered sailplane.
Given a more "ordinary" planform, I think you'll need 8 hp or more. I have a past design that flew well with 3 hp on a 10kg airframe. It would not hover, but climbed fairly well.

Yes if the wingspan of the aircraft is large enough.
Gary thank you very much. The aircraft diameter is 16cm, length is 1.5m and i am looking to a wingspan length of 2.4m but know that i have this sorted out what type of airfoil do you think would be necessary ? or what should the cord length be? sorry for all the questions but i am sort of new to this.
Thanks
Hi Johan, I think you will struggle to lift 20- 25kg with a 2.4m.
If its your first aircraft start small with a 40 size trainer and learn to fly that first and then perhaps head off to something like this http://www.amr-rc.com/products/aircraft/kits-to-be-assembled/airpla...
That should lift a fair old weight and the design work is done for you.
Thankfully these days you can design stuff without cutting wood, some links
