23cc Aircraft
I have a converted Homelite 23 cc engine that I have done my self, with all of the advice that I could gather from this section. It is an OLD ONE but still runs very well.
My questions areas are as follows:
What would be the correct prop. for all around flying, and aprox. what wing span/cord/fuslage length should I pursue to design an airframe for this engine?
Could any one suggest a weight limit?
I am starting from scratch and would like to acheive an all around low/mid wing aircraft to "play with".
I will build this craft from scratch so any suggestions could/would be inc. into the design. I do not fly compition so this is not a consideration(sp?) for me. I am TOO OLD for that.
Anyone around Dallas? I am in Mesquite, and would love to have help!
Any and all comments will be appreciated.

RE: 23cc Aircraft
Lee,
I'd try a 16x8 prop first...if it spins that prop any faster than 8000 rpms then get a 18x6...if that "feels" like too much or the motor gets really hot, trim it to 17 inch, the fatter blade of the 18 inch props are nice with the gassers.
I fly my 31cc Ryobi's on giant foamies. Super easy to build...knock-around type fun planes. You can see my Big Pink at www.crazyherb.com
Look for anything with 1200 sq inches of wing area or more. These old motors are a little heavy for their output and wing area is your FRIEND to bring down the loading.
You want to look at ready to fly weight at less than 15 lbs.
Don't expect this engine to fly like the $500+ powerhouses you can see on IMAC...but you can still have A LOT of fun with them.
If you're a good pilot and looking for a unique plane, I'm drawing up a gasser powered Delta wing that would work great with a 23-25cc gasser.
The increased wing area and reduced weight (no fuse or tail) helps a bunch...
(see attached image)
Best thing is...you got a good running engine...go have fun with it!
Good Luck!
