If you are purchasing iFlight 2207 motors, it's essential to ensure you have the right threading for your FPV setup. Typically, the threading information is available on the product page or in the specifications. However, if you can't find this information, you can consider reaching out to the manufacturer directly for clarification. You can try contacting iFlight's customer support or check if there are any forums or communities where this information might be shared. Additionally, you can search for any tutorials or user reviews online, as experienced users often mention such details in their reviews. It's crucial to have the correct combination of CW (clockwise) and CCW (counterclockwise) threaded motors to ensure your propellers stay securely attached during flight.
