RE: Homelite 25cc for Concept Fleet Bipe?
These are all powered with Zenoah G-23's. All fly very well at sea level when the engine is tuned to turn an APC 16/6 around 8000 rpms. The lightest one is the white single wing at 15 lbs. The Cub is 17lbs with floats. The Lazy Ace bipe is 18+ lbs with floats.
I don't know your altitude but if you can turn an APC 16/6 or a 17/6 your Fleet will probably fly very nicely with the 25.
