Not only does David make amazing products but he messaged me after reading my post and offered to send me a new prop to replace the one I lost! Thanks David!

David said they donât have problems with the props coming off because they use a soft start on their ESCs. Customers who buy just the motor tend to have this problem if their ESC isnât programmed properly.
Wouldnât call a soft start to solve this issue âproperly programmedâ. A prop should not work itself loose, period.

My whole motor axle is moving half mm front and back. Check out video: https://youtu.be/wW6ui66Su8Q
Is that something to be concerned about? Should I open motor and check bearings?
