The 919 (uses the 918 engine found in the earlier Blades) isn't a high BHP producing motor, they have been re-tuned for lower down torque - I think they're running around about 110BHP - There isn't any real need for anything higher (the top speed of one is about 140MPH/224KPH)Just posted this same question in the wrong section, my bad. Anyway, super interested in the 919. Tryin to get a new one but I am just curious why the redline is so low. I know its a low end torquey motor. Any one know?
