So on the first flight of the day, on a new build, I took off only to find out that this particular battery was dead. So I circled right back around came towards myself and was trying to be careful because I was standing on pavement. Well I made a small mistake and cut the throttle pretty much fully and belly flopped at which point I immediately disarmed. The quad hit with enough impact to tip over and that's about it. From my camera view I was no more than waist-high. Swapped out my battery and went for the second flight only to find out that I had two motor bells that were bent from that level of impact? The motors on the quad are brother hobby VY 1507s. Should this have been enough impact to bend two motor bells?

I've learned that the predominant believe in the community is that (a) quads break; and (b) get over it, and (c) always have replacement parts because of (a). It feels harsh but that's kind of the game. These parts are mostly crap. The ones that are built to a higher quality standard are "probably" more durable but cost more....even those will eventually break.

I've begun taking the attitude that "this quad hasn't broken yet" since I know it eventually will and I have a couple of backups that I can fly until repairs are done.

FWIW - I live in a rural community so I've never landed on pavement but I would assume that landing on pavement is going to break things. My foe is trees.

I've seen people break arms on a frame by falling from a height of just 5-10 metres. It all depends on how the quad lands when it hits the deck. It's all just luck of the draw.

uaw makes a huge difference about durability, some frames are made to carry a lot weight some are for low weight settups. a good frame for a heavy settup should have good carbon protection for the motors, while a frame for a very very lightweight settup doesnt have to protect the motor.

my experience is twoblades give much more often motordamage on the bell than triblades.
if the force came upsidown on the shaft directly, they have to bend as they wont break...

i beleive there is a discount for chinese new year directly from brotherhobby, you might get them at least a bit less expensive.
i would contact them and tell your issue friendly, probably they send you two new bells??

Thanks for the replies. I should clarify that I know things break. My question was did these motors break too easily? They advertise them as "cinematic" motors. I'm wondering if on a 4" micro reverb the durability is going to be an issue.

i guess its just marketing, nothing like different durability..

Cinematic as in flying gentle with a GoPro.
That doesn’t sound like a gate bashing race motor that will take a beating.

The 1507 probably bends easier because I am almost certain the prop shaft is aluminum and integrated into bell.
They say the shaft is steel but I think they mean bearing shaft not prop shaft.
Magnets won’t stick to prop shafts so I’m guessing the magnets aren’t rubbing the stator but the prop shaft wobbles?
I have a set of 1507 and I am almost certain the prop shafts are aluminum.
The t-mount type of motors may have some benefits in terms of durability.
