ORIGINAL: FLYBOY
The size won't matter. Its a great flyer and if you blow it up a little, it will still be great. No dihedral will make it fly a little faster and roll a little faster but it will be a fun plane. I would consider putting a ST .75 or .91 on it though. Would be a fun bird. Heres mine with 4 engines.
Your plane is awsome! I have a Jr. falcon kit designed for .049 - .061 power, I wonder how hard it would be to make it a twin engine?...
