RE: Mini F-16 vintage project consideration
Do a search on Cyclon engines, Foras, Rossis, Nelson .15s..Profis...
Even though high rpm model engines are gutless you should be able to remove blade area on EDF fans until the engine is revving where it should. It's always a juggling match between diameter, blade area, blade thickness and pitch. Plastic props can be shaved / scraped with an Xacto blade. High timed engines hit a wall if you slightly overload them...they all have an invisible line you can not cross with load.
