G+_610GARAGE Posted July 10, 2015 Share Posted July 10, 2015 I don't know why, but this is a lot of fun. Although, I need to switch to my 9" props (vs 8") so that I can have it free fall longer. :) Link to comment Share on other sites More sharing options...

G+_Eddie Foy Posted July 11, 2015 Share Posted July 11, 2015 Wonder if we can incorporate 'regenerative breaking' on a free fall. (in all honesty, that on a car is just feel good snake oil. It generates so little, it probably doesn't 'pay' for the added weight) Link to comment Share on other sites More sharing options...
G+_610GARAGE Posted July 11, 2015 Author Share Posted July 11, 2015 Eddie Foy I believe all regenerative braking is is running the motor backwards, in such a way that you create a high enough reverse voltage to recharge the batteries. So it would be feasible, but I doubt noticeable. Especial when you punch the throttle to get out of freefall. Side note: On cars, I believe the biggest advantage of regenerative braking is your breaks lasting 100,000 miles. At least that's what the cars salesmen claimed.

G+_Eddie Foy Posted July 11, 2015 Share Posted July 11, 2015 Yup. Using the electric engine to brake is good (its a horrible thing on a gas engine. Those connecting rods don't like that) The energy produced by the regen is basically nothing. Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted July 11, 2015 Share Posted July 11, 2015 I got about 100K on my brakes, on my just gas car. Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted July 12, 2015 Share Posted July 12, 2015 About the regenerative breaking... Just pressing the break peddle isn't the only time a hybrid is regaining that power. When a driver removes his foot from the accelerator he generally expects the car to slow down - partially from wind resistance and partially from engine breaking. With a hybrid the gasoline engine is disconnected entirely and the deceleration fealty is basically the same as the regenerative breaking. I recently exchanged my 15 MPG Expedition for a 40+ MPG C-Max, so the hybrid tech has become a major interest. I was originally going for a Focus, but so glad I got this instead! The other thing I noticed that allows it to really save fuel is just the fact that the gas motor will shut down when it's not needed... Stop lights, heavy traffic, down hill coasting... As for using the regenerative breaking tech on quadcopters, I agree that the power regained would be negligible. During a free-fall I doubt the air has enough power to move the props with any speed. If the props don't spin, there's no power to push back into the batteries. Link to comment Share on other sites More sharing options...
