Upon arrival it did not work. Dead batteries in the remote.
Changed batteries, still did
not work. Whoever made mine went WAY over the to with the hot glue, and there was a blob blocking
the spinning arm of the motor.
Worked for two days, but now the motor has stopped working.
This is a great prop. I had one before that I loved (but also was constantly repairing).
I just wish they would make it well.
