David,

Yeah, I was figuring something like that for the front top also, With a canopy, so a cockpit could be cut into the foam part is desired. I wasn't doing it on the 120, but I could offer it. The 80"+ wing thing will be pretty cool. I am doing the Banshee and the Mach one along with the Tipo to start with, then who knows which other ones.

The .10 and .20 might have a slab fin, not sure about the stab yet.

I am also about done with CAD plans for the TIPO.. I'll put them up when done. That would make scaling much better. The problem that delayed the short kits was wood sizes, and their effect on fuse side size, etc. When scaled, the top blocks aren't standard sizes, nor are the tri stock, so they end up either shorter in height, (so the outline isn't to scale) or taller, and need more carving. Redoing the wood sizes, and altering the fuse side sizes to keep the ouline where it should be, is what I am doing. I hope this explanation makes sense.

I wasn't happy with simply scaling the parts, that is what delayed doing the short kits. Anything worth doing is worth doing right. I have standards to keep up.

If you have the dimensions for the other size retracts, I could include the cut blocks.

Changing the wing sizes presents more issues. When you change anything like chord or thickness, That causes the wing opening in the fues to no longer match, etc. I'd rather keep the wing the same, but lengthen it when cutting if a customer requests. I would keep the tip the same, which would slighly change the tapers when cut. Or I could leave the tapers the same, and just cut it longer, which would reduce the tip chord. All of it is easy to do with the CNC wing cutter. Changing the fuse cutout for the wing when changes are made is another story.

Oh yeah, one other thing. All of the Tipo wings and stabs will now be full foam wings, i.e.: they will extend to the TE, so the ailerons/elevators will be cut from them after sheeting, by far the best way to do it. If you want to use a standard wood TE, simlply cut off the foam you don't want before sheeting. This way it keeps tries to keep everybody happy.

I'll keep you all informed.
