RE: Seacruiser II
The Sea Cruiser II buils as the designer intended is forgivin, stable and capable of some mild aerobatics. Some of these have been built without dihedral, some have been built with a semi-symetrical wing all with good and expected results.
The .40 size can fly with engines smaller than .40 and a friend has one with a .71.
They can be built with wheels.
The fuseelage being plywood is about as strong as a baseball bat.
This is a very, very good airplane kit. And an excellent flyer
