After completing the Air Race Jet, I found that the upper fan door does not close completely (stopping short by about 1/2 inches) when I switch from VTOL to Flight mode.
The attachment points to the pulley pieces operating the door seem correct, and the engine nozzle and flaps move into their correct positions.
So I have not been able to see what is blocking it. Any ideas on fixing this?
I did notice that the two gray pieces that support the black engine nozzle cowl are shown as upright in the instructions, but are slightly slanted in my completed model. I wonder if this may be related.
Yesterday I contacted LEGO customer service about my non-closing fan door problem, after disassembling about 30% of the model in a vain effort at finding the cause. Their response was that there was nothing wrong and this was normal, even after I sent them Youtubes showing normal operation and a video of my issue.
So in addition to asking for any input on fixing my problem, I’d like to also ask anyone familiar with this kit if you agree that there is a problem.
Well, I decided to call customer service at LEGO, and a very helpful fellow confirmed the existence of the defect in my model — doubtless a mistake buried somewhere in the 1,151 parts, as I thought. So back to my question - where should I look for the defect?
He suggested focusing on the area depicted below. You’ll notice a yellow crossbar going through two gray support pieces. With the doors shut, they should be flush against one another with none of the yellow showing, but in my model they have a gap when Flight mode quits, as shown. If you manually push the doors (top or bottom) shut, they are flush. So this area may be key, or (shudder) just an artifact of a mistake elsewhere.
