Very nice airplane but you must be joking about the Z62?
I have flown a 3rd scale Tiger using the Toni Clark Z38 and reduction drive swinging a 34(ish) inch prop.
Simply superb, nothing I've ever seen or heard has been more scale than that combo.
Even on the ground, idling in the mid 100s rpm the sound made the hair on you neck stand-up... just prop noise.
Loads of power to... then again, maybe not as much as the 62!
Congratulations anyway... you've sure built a pretty airplane.
