RE: .76 engine in a trainer??
As a beginner on a trainer, that big of an engine will get you into a lot more trouble than it will get you out of. In fact a good 46 is a lot of engine for a trainer. If you want to use that engine most defiently you need a 60 sized trainer.
A 76 sized engine on a 40 sized plane and wings that are fastened on by rubber bands... not a good mix.
I also second the recommendation on at least one more plane between the trainer and warbird, or at least a good bit of time on the buddy box with the Corsair.
I think a 60 sized trainer is great to have, I wish I had been able to start with a bigger plane.
