I am about to start building my lancair 360MKII kit and I am planning to adapt it for a UL520T engine 220HP Turbo Normalized FADEC engine. Initial plan is an Airmaster electric constant speed prop but that could change.
The UL520T is lighter than io-360. Maybe as much as 87 lbs! Any thoughts on challenges getting CG correct losing that much up front? Maybe use a metal prop? Hub backplate or longer cowl?
