While playing with straightening the wing (it's probably straight enough to finish the job with sheeting the bottom), I roughed-in the front top piece over the engine compartment. (Images attached.)

Right now it still covers quite a bit of the engine. This may vanish once it's shaped. But if it is not sanded away, should I leave it as is, or should I open up the top piece more? (As it is now, I would attach an extension to the needle valve to get it into the open.)

Thank you,
Richard
