I have one of their Star Wars X-Wing drones that I just purchased. It is not flying at all, and I just got it out of the box. My son is very disappointed. It never leaves the ground. It looks like one of the motors doesn't even come on at all. Propel stated that it's discontinued, and would only be able to troubleshoot. The manual states that it has a 90 day warranty. So much for that. User's recommendation: I would suggest to avoid Propel. They will not honor their warranty at all.
