[HELP] Problem with 42066 VTOL function

[Ngoc Nguyen]

I've rebuilt 3 times and made sure I followed the instruction precisely, but this is what I've got:

 

 

The hatch already open to the maximum but the nozzle doesn't go down 90 degree. Does anybody else encounter this?

Isn't there some sort of gearing to ensure that it does go down 90 degrees?I don't see it.

You have built it correct.

Confirmed - this is correct.

Can anybody with the set check out if your set behaves the same?
