I am thinking about buying an omp profile edge 40 size to screw around with 'til I get my big edge goin'. I want to spend as little money as possible. Would a Towerhobbies .46 be a good engine? I would rather buy that than spend $120 for the OS. I was also looking at the magnum 46. It looks like a direct copy of the OS 46 FX and costs only $80.

Thanks
