Here is another not quite conversion that I have done. This is a KenHi Panther outline that has been scaled up to 84" span and has had the tail moment increased to make it more like a 70s vintage pattern plane.
It weighs 17# with a Moki 1.8 for power and flys like a slower version of a vintage pattern plane.

I have thought that I might take the Thunderbird design and stretch the fuselage to see what it would look like.
