Top plate is a weak link

Update to prior review. Its not OK

Well I now know why it fell out of the sky. The motors crapped out. Do your self a favor and just purchase the frame and maybe the control board but don't buy the kit choose your own motors, in true Rotor Riot fashion they sell cheap parts at very expensive price. Like a dummy I did buy another motor, I just did not want to purchase 4 new motors for a kit I spent nearly 515 dollars for, in hopes to get this thing in the air for longer than 2 minutes.

Its OK

So far Its ok at best. Nothing to brag about here. The build video came out long after the kits were sold so in other words you looked at pictures to figure out how the build was to go. Not hard to do though. The other problem is the cheap components (opinion) On the maiden flight took her out anf gave it a good punch up and it fell out of the sky faster than it rose up to. What caused the crash is unknown at this time but no other build that I have done just quit working so... It is a tough frame though like the name , it fell like a rock, but completely stayed in tact like a tank. Will give it another go and if there is improvement Ill say so and may even change from 4 star to 5 will just have to see.
