Clean wash for tail. The post in not so long, just normal length.
Sometimes the wing tip touched the ceiling, but the prop touched much much

First touch to the ceiling time was between 1min30 and 11min30.
Yes, it took 11:30 to touch the 7.4m ceiling.

No and No.
No downthrust. No stick bow. The bracing wire is very tight.
