And I know what I did first time round - when adding the inch on the front to help balance I pulled the jig forward leaving the tail former in the wrong place

Make an intermediate former and rejig some stringers; keeps the plane from getting tail heavy, and keeps the proportions right.

Awwwwwwwwww - I've looked at that inside former; take the old former out, make a new interim former, keep the stringers in the right places, CR**! FUBAR!

For the 1/2 inch involved, adding a new end piece is a lot less effort. By the time everything is done the stab will be 6 ounces again, with an extra 1/2 inch on the balance arm.

Proporations are already screwy because I lengthened the nose..... Swear Word

And the tail wheel mount is on that inside former..plus the fuse, from the second last former to the end, is sheeted. Stringer work is minimized, my FUBAR gets hidden, I'll put 1 servo inside instead of 2 in the stabs, balance won't be tooooo bad with 1/2 inch overlong, and I can justify till the cows come home Cheesy

Since i have to add the horns, and cover, gotta get as much off as possible. But then, haven't sanded the stab yet. Likely get an ounce off total, but add 2 back on. woohoooo!

another 10th of an ounce.....the center gets cut out, be replaced by brass tube attached to one side only - for esthetics Angry

. I'm going with 2 servos inside, try and keep weight off the tail.

Dubro Ball link control horns. Think they do an unobtrusive job, and their bases will be covered by the fabric..

Steve - "flaps messed up.........turbine" it's all there in the one comment. Blow torches and carbon; don't think so... Roll Eyes

Having duly considered the effort to move the inside former and reset/replace the stringers, I finally went with the quick and dirty approach, giving me a "not perfect but kind of OK" result.

Data line down the top centre stringer, plum line down the new end piece, lots of clamps, forgot the glue and had to take it apart, ADD THE GLUE, then realign and re-clamp.

Once the stab is on, the fin is on, and the fuse under the stab is covered with the scale sheeting on the tail, only Mike, Glen, Cool, a few thread watchers, and I will know it's wrong.

On the bright side, a screwp that would normally ground me for about 2 months has been dealt with in only 3 weeks. Raa Raa

AADD be darned!! In the process, I've confirmed a long held belief among aircraft builders.....

FUBAR/SNAFU = TLAR

Oh yes - the addition is 3 plys of 1/4 ply, plus 1 of 1/8. Hollowed out inside it weighs .64 oz, so I'm going to have to build in 3.5 ounces up front to offset it.

Just saying.... Also I thinks you will find far larger sin in the real macoy if you were to dig. Keep going Sandy. You may not have to will that to me yet!

Well done. As it zooms along the flight line at 5 metres AGL all that anyone will notice is that it looks like a proper fighter.

Well, I needed more weight on the nose to offset the FUBAR'd tail former "fixed" about 6 posts ago... No Whine Zone

The engine I was going to use won't work. Being a copy of an old 3W, the carb is on the side, and just will not fit under the cowl, requiring a humungos/hemungous/homingis ... very large hole in the cowl and carb sticking out about an inch. Crappy Day

MikeP would never forgive me.

So, Margaree Night

I have to make a 1 1/4 inch engine box to stand the DLE off from the firewall. Oh joy oh bliss Swear Word

Well, this makes the prop plate just clear the front of the cowl (once I cut it up Wall Bash

) and also moves the CG ahead... Smiley

so I guess all is not lost..

Gonna hate to make that first Cry

cut

in the bottom of that nice, smooth firm round piece of fiberglass joy, so well ...... Sad

sorry..

I'll be careful.

I also have another 16 5mm bolts, 2 3/4 in. long if anyone needs something like that..to go with the 40 or so 5mm x 2 1/4 in. bolts.

It looks pretty neat and tidy to me. Curious to learn what sort of muffler you will be using. Will it be mostly inside the cowl'?
