RE: Buyer Beware - Extreme Flight RC poor customer service
I'm sorry for your loss. but I know to use locktite on everything whether or not it's called for in the manual. Knowing this came from the same experience you had with a failure.
I build for other people and have learned no matter how good the manual is there are always things I will change or add because I've learned the hard way.
If you liked the way the plane flew get another and assemble it your way. Dennis
