The Thunder Tiger 46 Pro is nearly as powerful as the OS 46 AX at a much lower price. A good value for the money.

And listen to JownW about HP ratings. The manufacturers all try to outdo each other in HP, and do their evaluations with props that are much too small to be practical. (They'd fry the engine in a few runs.) These evaluations are also done way above the maximum torque ratings, which is what would actually be useful to know. Unfortunately, very few (if any?) manufacturers list torque in their advertising. []
