After a long time, I got to the quad, with which I have flown quite a lot, it was lying around for a longer time, I didn't have time for it. It flies fantastically, but it has one flaw, it uses T-props. And that is really a problem and really unpleasant and dangerous at the same time.

I don't know about your experience, but all T-props in the 5 inch light weight category that I've tried, whether Gemfan or HQ, always tear in the hub after a while. It is very dangerous to use them. All it takes is the slightest touch of a branch or a thicker stem of grass, and the propeller will crack in its hub. Then just add throttle and the prop will be torn apart. Today, I think it was the fourth piece of the prop that broke like that. Also, when I flew in the winter, the props were all the more fragile.

I took out the bags of new sets of props, 4 bags in total, and examined their hubs with a magnifiers. All, I mean all the pieces had hairline microcracks on the hub, always only superficial, but they were there.

Shit, what is this? I just have a faulty series, or you have the cracks there too.

if you are using locktite, its the reason for the rotorfailure.

so far i didnt get that experience on my gf5125

I don't use Loctite on the prop, it's unnecessary, Loctite is for metal to metal joints, not soft plastic to metal.

And you don't have any cracks on those props? Either Gemfan 5.1x2.5x3 or HQ 5.1x2.5x3. I have hairline cracks even on new unused props and on both types.
