The OS15 LA is quite light so it would be great for your Formosa.
I've used an ASP 15 on a balsa Extra 300 of around 900mm wing span and it can almost do 3D - due to a little more power produced by the ball-raced ASP engine, but there is a weight penalty. I recently got a Magnum 25 (also ball-raced) from a LHS and it weighs almost the same as an OS40 LA

Anyway, can't beat OS quality... the MIC engines need a little more tender care in running-in, but if they get past that stage, they are little powerhouses for their small size.
