The choise of the 2 x 70 Surpass seems excellent, the 90 might be to heavy and not really necessary.
I still have the moulds to make the cowlings and nacelles but unfortunately I cannot manufacture these items for you. I am currently working on two other time consumming projects : a big Corsair F4U-7 of 2.50 m wingspan and I am also restoring an old car.
But if I you come in France I can borrow you the moulds (to heavy to be sent by mail,DHL , UPS or similar) if interrested contact me by mail.
Back to the tail: I cut the keel out of 3mm lite-ply; I cut it a little bit longer and higher.
Prior to CA it in place I had to make sure all the slots were aligned. That meant widening some of them: when it happens I prefer to make the joint tight by forcing some balsa into the slot to achieve a snug fit again.
I also decided that the slot in bulkhead C31 had to be deepened to accept the keel.
After you're satisfied with the fit, simply CA the keel in place checking everything is square once more.
Next are the remaining 2 10x5mm stringers (basswood): again check all the slots align and since the fuselage tapers, file all the slots to the appropriate angle. If the fit is poor here and there, gap with scrap balsa.
Yesterday I finished the hull. I will sheet it before proceding to the next steps since the fuse is upside down over the plans and the sheeting itself will keep everything aligned.
I nice day of trimming here and there.
I started with the MAIN GEAR BOX sides: simply cut them following the -slope- of the hull.
Sand all the formers flush with the keel or viceversa. You need to sand down the lowest stringers as well.
Former C34 carries some designing mishaps: I noticed it earlier in the process but left it in place; it is very easy to correct.
When dealing with the taper on the lowest stringers you'll loose every reference past former C42: help yourself with a ruler and draw a line that will guide you through the rest of the sanding.
Here is the rudder post after the internal balsa reinforcements (as Kmot suggested) and sanding.
I wanted to better support the sheeting around MGB and installed those balsa -ribs-. May proove helpful.

Last are -formers- C43, C44 and C45: use 3/8" wide stick (always 1/8" or 3mm thick), cut longer, place, trace notches, cut and CA in place, sand flush with hull.
That's it! Sheeting next. I'm pretty curious since I'll use Gorilla Glue for the first time. Let's see how it performs. I'd better get used to it a little prior to...
