That's exactly what I was thinking to do, pin the block to the side[8D] . I'm also going to make 2 supports from 1/4 inch balsa to give the block more support. Everything is going together well so far.
One area that you have to be careful with is the placing of the formers. Former A,B2,F,G and H are straight forward. I installed these in place then aligned the fuse and glued. After the glue dried I lined the fuse up with the plan again and positioned Former B and C. Be careful with former B, the landing gear blocks require the spacing to be perfect. Glue the 8 pieces to make up the 4 landing gear blocks and fit the entire setup together dry, then glue. The engine box went together well. I re-enforced the entire box inside and out with 1/4 triangle stock and I will be pinning the firewall as well as the 1/2 triangle stock it is glued to. Have to look after the MVVS 1.60
I have also opened up all the lightening holes on the fuse sides. I am going to try and build a one piece elevator and use either a carbon fiber fiber rod or pull pull on both rudder and elevator. New area for me, but I like the idea of no exposed gear and hoping to be a bit lighter.

Really happy that the fuse is complete and assembled. I was a bit worried there in the beginning [:-]
