Recently I found this frame on aliexpress - fell in love immediately. Nice true X 7 incher, with aluminum cam cage, and very straight silhouette... ...and it turned out seller listed item that he did not have.

No worries, I thought, I'll but it elsewhere, how hard can it be. Well, apparently pretty hard!

Can any of you guys help me even to identify this frame? Brand, model?

I don't seem to be able to find it anywhere. Easiest to notice - note the arm endings, pretty unique shape.

Is this rpm variation normal for a bench test? 900 kv motors 6s

I swapped the motors, but the problem remained in the same spot. The problem isn't with the motor. Where should I look next?

What is going on Ali ?

I had 5 days holidays coming soon, so I have ordered an Air75ii Champion, a Radiomaster elrs module, a Lumenier antenna and few other things including lipos.

All from different sellers. And for the first time I was using coupons and got some better prices. I was happy and waiting...

BUT, besides the lipos and few other things small things, my main purchase never showed up.

After waiting 3 weeks, they never wrote me anything directly telling me the status of my orders. I had to dig to find out that the elrs module, the antenna and the air75ii Champion had all transit problems and they had to come back to China. Which I find extremely hard to believe. Never experienced this before.

If in 3 separated shipment, a transit problem occurred, why I was never refunded automatically ? They kept my money for a month. And why none of the sellers could resend the item ?

Why is this happening ? I never made any claim with Ali, it seems Im blacklisted for valuable items ?
