The kit sucks. I got mine yesterday and I hate it and wish I didn't spend the money on it. I should have spent the money on fixing my HDX450. The biggest problem with this kit is the fu^king screws they used. There not hex head but more of a "star" shape. They all strip out very easy and of course the tools that come with the kit suck really bad. I already had to order the Align tail boom holder $20 and I'm going to probably find myself ordering the Align screw set too, another $15 with shipping, if I dont throw it in the trash first. With the crappy screws as tight as I could get them, the tail boom still wasn't tight enough and the belt came loose in flight. The heli headed right for me. All I could think about doing was throwing my hand up and the main blade damn near took my thumb off. Cut the hell out of it and it took forever to stop bleeding. Aside from that, I killed one plastic blade, tail boom support, tail boom and feathering shaft. Total damage $25 in parts now needed. People told me to save my pennies and get the Align kit and that would have been the smart move. Guys please dont waste your time with this kit. Its nothing but a dumb investment. I doubt I'm going to waste my time and money on fixing this and simply cut my looses.
