I finally got my 6 cell battery in my new Max Bee (a special built kit from Tom Morris) did a quick test run to see the delay time from push the button to spool up. 30 second delay, but when the motor started, off flew the prop and spinner. Such fun. Installed a new prop, but made sure it would not come loose and got over tightened and broke the shaft. New shaft went on today, now to find that darn spinner. Such fun.
