RE: ESM 50cc Corsair
I've heard those and I'm not too keen on cleaning up oil unless it's from a smoke system. They do look nice though. Moki's are mesmerizing and I'm too entranced at this point. I've been saving pennies and looking at P47, corsair, Yak, even sea Fury ads for months in a 100" size radial warbird ARF. Corsairs always look best to me and a smoke system won't foul the wheels cause they fold straight back.
Money's not the issue. The Issues I can forsee are strength of wing, gear (bigger springs?), engine mount. And how bad will it bite in the turns with 6 lbs of extra weight compared with a "proper" setup.
