Just started building a Hangar 9 Aresti 40 and noticed some problems.

When installing the horizontal and vertical stabs they tell you to cut the ultra coat covering to expose the wood. This is good but when you go to install them into the fuselage the plastic film catches and doesn't go into the opening and buckles up. I tried to iron the ultra coat in place after cutting it away with some success.

I also plan to mount the engine upright rather inverted as shown in the plans. Will I have any problems with this engine mounting change.
