Default RE: Designing a new pattern model

I recently returned from my trip to France and started working on the model again so i'm back with an update. I have both bad and good news so here we go:

- The bad news: I really messed up the finishing process for the wood fuselage. Trying to fill all the gaps and seal the balsa surface, i covered the fuselage with a layer of dope and talc mixture. This worked perfectly for the rudder so i thought it would also work nicely for the fuselage, but it turned out it to be a bad decision. The balsa skin was softened by the dope and created slightly concave shapes in all areas where the balsa was curved and forced to follow the shape of the formers. To make things worse, this also results in a lot of added weight because it's difficult to sand the excess mixture in the concave areas.

The only solution would be to strip all the balsa sheeting and start over, but it would take too long and, as you will see, i have other plans. I won't give up on the wood version and the plan is to finish the fuselage as it is and get the model in the air as soon as possible. I mounted the landing gear and tailwheel and quickly fixed the canopy in place with a few screws:
