Will I fry my esc

I'm currently running dd sp400,5.5x4.5 prop, 8-cell 600AE and jeti 10 esc in my S&B corsair. AUW right now is 16.04 oz.
Can I put an sp480 in it with out frying something?

Thanks, Glenn

You damage the ESC if you put too much current through it. So you could use 480 if you put a small prop on it so the current stayed low. There wouldn't really be much point doing that.

If you want the full power available from a 480 it would need more current than that ESC (and probably the battery) would safely take.

A stock Speed 480 is a 7.2V motor, and will draw less current with the same prop and battery when compared to a Speed 400 6V. However, I wonder if you're running a 6V motor as it would draw over 12A with this setup (the stock Speed 480 would draw 11A and give almost identical performance, as it's a larger and more efficient motor, although it is much heavier). The 7.2V Speed 400, however, is only drawing about 8.5A, so it's probably what you have - in that case, moving to a stock 7.2V Speed 480 would make a difference, but would be too much for that speed control.

Thanks for saving my esc guys.
Andy I am running a 6v 400. 5 flights so far, two of the with a 3 blade 6x4 prop. Guess I should get a 7.2v before cook the esc.

Thanks again for the info guys, Glenn
