A wee bit more done this weekend.
The two engine pods are framed up and just need sheeted. Started to mark out foam for the wings only to discover all the bits I have are about an inch short!!
Wings may have to wait until January. :cry: :!:
Over the next couple of days, I hope to get the tail cut, ie two all flying elevators and the vertical fin.
After that I may move across to the Jart until I get the foam for the wings :?:

Quite on this build for a while, so I did a little today.
After looking in a lot of websites for a bellcrank of the right size.. I gave up and bought some pcb from Maplins and fabricated my own.
Sorry about the pic. My camera's playing up, so this is taken with my phone
Going to do some more work on the engine pods tonight and possibly cut the wing tomorrow. Will start with the tails and see how it goes.

Got the sheeting done top and bottom of the fuz today after installing the control horn:
Noew ned to start shaping the fuz edges to get a "slightly" more rounded shape. First of the top decking has been shaped in blue foam and is currently sitting on top of the radiator with sheeting drying. This piece will run from the back of the cockpit to the LE of the wing..
All in all a productive weekend, (for a change!) :clap: :?: :?:

Good stuff Bill. Sure you're flying along now!!

Got a bit more done tonight: Tails are cut. I used a single point taper cut to do these as they are small and quite highly tapered. One end of the wire is stationary and the other end swings through an arc, cutting the foil as it goes. Very pleased with the results.
This is the cutter. The far end is on a pivot (Screw in this case)
Planform of the tails
The airfoil section is SD8020, fully symetrical. Will have a balsa skin adde and a balsa LE
