I did a Spit a while back.. Now hangs proudly from the ceiling of my office. It would proberbly still fly if converted to E-power.
It started life with a Pee Wee. Flew great on a good engine run.
An old .049 reedie was later grafted on... Quite zippy ..

I don't remember doing too many mods... I think I may have made the nose half inch longer and sheeted with 1/32. The fin a taste larger and a little more dihedral.
Aso an aeronautic PhD. advised to build washout in the wing (4 Degs) Even the full size had washout 2 or more degrees of twist I believe.
If I did another I would lose some of the wing ribs.
