Hey JohnM,

Nice to see you made it over...we won't say how the other site is drowning users in adds... Besides, we can use your humor here. Helps to keep things light.

Hey @acerc,

I love watching your Big Pitts fly. That slow motion Avalanche was COOL ! ! !

Started working on the tail sections of the EMHW Pitts S1 3.04m
Questions - does the attached pic demonstrate the correct location of the single attachment point for the flying wire on the fin ???
Since the top side tail section has only 1 flying wire at the trailing edge of the fin/stab, does the front stab tube need a screw or pin to keep the stab from gapping away from the fuse ????

Thanks - Jaketab

That hard point looks right and I put bolt's both front and rear on mine. In the pic the arrow is the same on mine as yours. But on another note, if you are going to use the kit provided plastic strip to pull the fabric in at the bottom fin rib I would recommend replacing the balsa with hardwood. But if you are going to tie the fabric to the bottom fin rib no need for the hardwood, although it would be stronger.

I would also recommend reinforcing the fin at the points noted in the pic with arrows, especially if using a shrink applied fabric. I bent bot on my first one.

Ace - Excellent tips I may not have caught. The balsa ribs on the fin are already installed. I may try harden it with CA or thinned epoxy.
I will certainly brace the fin.

Thanks - Jaketab

Ace - on my 58% Pitts, the plans for the fuse are not 1:1 as in your plans and not quite as detailed.

That's ok, you know me, I document everything for future reference.

The framework has been disassembled and ready. Now I will do some final sand and fill as needed per section and cover, I will start with the tail feather as they are going to be the biggest pain. But first a break to go fix my breaks. The rear pads are shot and I need to replace them before heading out for anything, such as some grub. Don't feel like cooking.

I'm documenting my build with photo's. I won't be posting the pics to avoid rehashing of matter.
Just sharing the how I secured the perimeter strips of the tail sections.
