RE: Who all overpowers their plane? and which plane and engine
How about:
Jett .50 on 40 sized Kyosho Spitfire
Super Tiger .90 on a World Models Chipmunk
O.S. .25FX on a Ace Baby Ultimate Bipe
O.S. .91 FX on a Kyosho .40 Sized Gee Bee Z
Jett .90 on the Hangar 9 60 Sized Corsair (Haven't flow this yet)
All fly extremely well (Except the Corsair (Don't know yet)), without any additional weight needed.
