The courier just dropped off these two motors. I ordered them direct from QS motors in China, only took a week to arrive from the factory. I've tried/researched/tested several motors over the last six years but these are the best quality I've seen yet. The 28H is rated for 800 watts continuous with peaks to 3k and the 50H will be a torque monster, it's rated for 3000 watts continuous and will take peaks of 12k watts. Looking forward to building these up, I've already started a project for the smaller one, stay tuned
