Bought Tello 3 months ago. Been flying fine. Last time flew, put away in case. This time, there seems to be a problem with the motor on the front right side. Just won't take off. Tried changing blades, batteries. Just seems to be that one motor but it was working fine last flight and no crashes. Can you help me?

Hi Queengee,  in line with your description, you can check these propellers first.
1. Please use the stock propellers.
2. Please check the propellers are in good condition and attached firmly.
3. Please check if these propellers are installed in the right position.

If persists, we respectfully suggest you contact Ryze support for further assistance. Have a great day ahead！
