Cox 1/2 A RPMs?
« on: March 18, 2006, 04:17:27 PM »
My son just finished a brushless outrunner electric motor kit and we tached it with a 5.5 x 4 cox prop at 13.5K rpm.  It has been ages since I had a tach on a Black Widow or Golden Bee.  What rpms would one of these Cox motors turn a 5.5x 4?  Thanks.

I don't have or use a tach, but I'm guessing 16,000-17,000 anyhow. Could be wrong.  Where are the experts?

Pretty close.  That is what we aim for in Mouse 1 with stock Black Widows.   ---DOC Holliday
