I will be following the Tigercat with very much interest.
I like the fuselage former/wing spar arrangement, it
should be strong and light.

I really like the way the spars, nacelle formers and fuse formers are all integrated. I've never seen that before. Its so obviously simple, strong and self aligning. Brilliant, as they say in the Guinness commercials. Can't wait to see more

Wing panel construction
Hi, just thought i had better let you see how the wing panel in made.
Plan stuck down and False L.E & T.E stuck to building board, these are cut so that you get the correct wash out on the wings.
Inboard, and tip rib stuck to LE & TE and upper spars fitted (Note wing is built upside down - you will see why later)
All ribs fitted and lined up with top edge of LE & TE.
Lower spars fitted.
It is now ready to be rubbed down ready for skinning.

More progress to the wings on the Mitchell, now you will be able to see why i skin the lower side first, its so that i can cut the slots for the formers.

Very interesting design technique Philip. Integrating the nacelle and center fuselage formers into the spars should really help with ensuring everything is alligned.
I like it!
