I've used the 11x7.5 propeller once (the plane landed bad and the prop was broken) and the engine seemed to like it (46FX). So I guess the 11x7.5 imposes no much load to the engine as one may think. Definately a 11x6 APC put more load to the engine as far as I remember, and it didn't flew that well with the apc.<div>
