Jim,

looking good. What I like is that the wing appears to balance by sitting on its V-shape base at the wing center - this means you won't have to mess around with wing tips or lead ballast to laterally balance your model - it might be pretty close although the pipe on the right side will require a check.

On an all wood model I wouldn't mount the wing with 3 screws as shown on the plans (I believe), it is faster and more convenient to use 1/4" dowels (use 2) in the front and 2 screws in the back (1/4x20). Setting up the front screw as is required in the glass model is not something I would recommend if it can be done differently. In fact, I plan to see how best to use two dowels on the glass model as well (a second one). Of course, until your wing is squared up and fully mounted you can't add the wing LE chin.

I think you might also find it more convenient to install Robart hinge points when your wing TE and aileron LE are still square. You can draw center lines and drill exactly at that point. Drilling straight into a beveled edge is tricky at best. Tack glue the ailerons on to the wing once hinged and do a final sanding to airfoil. Then, you can pop them off and bevel the aileron LE.

The stabilizer will be the hardest to align; a 4 dimensional positioning is required. Take your time and only use spot CA glue when satisfied. If it still looks good the following day and maybe the next...[8D], then proceed to epoxy it in place and run your fillets along side. It is easier to align the stab with the fuse cutout a tad oversize and then wedged in with scrap balsa shims - they are later removed once the stab is properly held by epoxy.

I'm dispensing way too many suggestions/approaches Jim but it is merely in response to our different building styles - do as you would - I just provide my approach to offer an alternative view. I wish I was the receiver of more of that kind of commentary in my builds - helps to think "outside of the box", so to speak.

Keep up the good work, you are close to having a fully framed up Tipo!

David.
