F450 Flame frame is not indestructible

[VABrown]

I ordered a DJI F450 Flame frame kit after watching their Youtube video (http://youtu.be/b5rjDVgJAVQ). They throw it, step on it and even drop it several stories out of window onto the parking lot.

I'm here to confirm, while resilient they are not indestructible frames. I've now had to "Flame Outs" that resumed in broken frames.

Eh UP Tom.. looks like you had some hard hits there..

Mine has had been used and abused for a couple of months now.. guess you have been a tad unlucky.. There has been a couple of threads on here about busted 450 frames.. I can assure you if it had been a Gaui / Alware or some of the other frames available right now you would not have just bust one arm!

I'm also wondering bout the temperature people are flying in. I hit mine hard into the grass and broke 1 prop. but I bet if it were really cold out the brittleness of the plastic would have not survived.

isn't hobby-wing in china? expensive slow shipping when the parts cost the same.

cnchelicopter has em, addictiverc has em, alot of dealers in US got em and have ya back in the air in a couple days

I was flying on a 36 degree morning since the winds were kicking up later on Saturday. Temp dependency is something I hadn't considered.

the difference between there indestructable test you posted and your crash is the weight of everything in the frame. Toss it around empty and you loose alot of the energy

I dropped mine from way up, lipo slid out....... broke a prop and bent 2 motors, frame was fine. 70 degrees

ive had some rough falls from between 8-12ft and no major damage as of yet. but looking to put some foam legs on for the time being to get the bottom of the frame a bit further off the ground to stop the bottom plate from smacking.

Welcome to the club. I taught Chuck Noris smaked my in the air since i broke it on the first day. I guess if Chuck flew it the frame would not break. I smaked one bum in 3 pieces.

No doubt that the 1/2mv^2 energy equation comes into play -- increased mass and a diving cart wheel produces some significant forces on the frame.

I still like it as my trainer . . . now if I can only get some spring weather without gusty winds in Virginia.

Cheers!

I had mine drop from about 30-40 feet yesterday, and the arms all survived, but I cracked the F450 top plate. Temp at the time was about 74F.

I do think low temps makes the arms more brittle. If mine wasn't so heavy (4-1/2lb/2.1kg...), the plate probably would've survived. The only other damage I had was two broken props.
