Carbon fiber hinge pockets continued!
I am done with the stab until I build the ruder. I will get to the stab tips once I glue in the joiner.
I rounded off the 1/8 balsa in the pocket. The hinge pin goes in very easy now, just lay the elevator in the pocket and tread the needle
The ruder is on the slab next!

So I haven’t totally ruled out glassing and painting. If I do paint it will be water base airbrushing. When the artist painted my giant chippy she painted it right in my living room with no over-spray at all. I know it will take a little longer but if I do a cam-o scheme it will be great for that. I could conceivably paint my bird in my shop with no over-spray and non toxic water base paints. I would clear coat afterwords to seal and protect. Any of you guys use air brushing and water base paints?

Face it Tony, a bird of this caliber deserves glass and paint. Plastic covering would be doing a huge injustice to your building skill as well.
If you need any help glassing or painting, my shop is always open. Besides, I like the way the fumes make me feel.

I use nelsons and warbird colors. Both are water clean up and easy to use. I use a harbor freight 5oz HVLP and a paasche airbrush for detail work. Both of these are warbird colors. I used nelsons on a wing mfg P-38 years back and it was the same for spraying. A buddy in north Texas uses Behr latex exterior house paint. My glass jobs are done not for strength, just to provide a good base for paint, and it does a great job of that.
Tony, PM me with the address of your shop. If you're there later today, I can stop by on the way home from the field.

Nice planes Edwin!
Today I started work on the fin and ruder. But first I went for some early morning flying. I was surprised when I had to open the gate. It was a perfect day, not cold, no wind, and I had the field to my self for a couple hours before my flying buddies started to show up. By noon I was ready to build.
I got the fin and ruder all framed up and sheeted one side. I am doing my modifications right now so as soon as I get that done I will sheet the other side. I am still working on the hinge location and the control pocket for the elevator and the pull-pull. Pics will be ready tomorrow.

RE: Top Flite GS P-47 sports scale; diary of a build
So I was doing some research last night on the ruder and noticed that this kit doesn’t have the bubble bottom on the ruder. I am not totally sure but I have been looking threw the treads and I cant find any pics that show the ruder with the bulge on the bottom that is there to match the thickness and couture of the fuselage under the stab. I am surprised TF did not build this into this kit. The 60 size ARF I built has it and all the other kits out there do too. So I think I need to put the ruder on the back burner and start on the fuselage. This detail to me is a signature detail to the Jug. If I can do it I will. If any of you guys know what I’m talking about and can shed some light that would be great.
The first pic is my TF 60 size P-47 ARF.
The second and third is a Miester ruder.

RE: Top Flite GS P-47 sports scale; diary of a build
I like to keep track of my building methods as it relates to how heavy or light I build. I know some of my scale detailing and tinkering sometimes adds weight, and the kits design is to try and keep it light so I always weigh the individual parts like the stab, fin and ruder, fuselage, wing halves and so on. This tells me how my building methods affect the weight of my build. I know wood can very in weight, I have seen the same size stick have a 2oz difference in weight so that also is a consideration when I select wood. Glue and other items used. I like to use carbon fiber whenever I can over steel.
So I put my completed stab all hinged and ready to finish on the scale and she came in at 10-3/4 oz. I still need to put the stab tips on and the joiner hinges but that should be under an oz. I am curious to what some of you guys out there building this kit came up with on your completed stab.

RE: Top Flite GS P-47 sports scale; diary of a build
Tony I kinda envy you watching your build. After I built the 1/5 scale mustang the p-47 was next on my list but I have problems with my hands. right one is the worst so I decided to go easy for awhile. I'm a bit like you, I build heavy partly because I like to paint mine and that adds some weight. When I glassed the mustang I put .56 oz glass on with dope because it's lighter than anything else and you can fill the weave with thinned Dap light weight spackle which sands beautifully and it will take any primer you choose, I used Dupli-Color filling laquer primer which works well. Don't know that you did the wing yet or not. Anyway, great build and I'm liking it. Leroy

I pretty much do the same as Leroy. I put one coat of reson and wipe off excess using the toilet paper method. Fill with spackle thinned to a heavy milk consistancy, sand to the weave and repeat until its all filled, then the high fill primer, then the base coat primer which is determined by base coat color. Grey or white. Makes a great paintable surface.

RE: Top Flite GS P-47 sports scale; diary of a build
Thanks Leroy,
I am getting excited about glassing and painting my kit. I originally chose to do iron on covering because I was planning a quick build with not to much thrills and tinkering but this bird has taken ona life of its own. So Gary my new revised completion time is three months! Edwin first told me about his way of glassing when I started building my chipmunk. I will try that this time. I don’t have any experience glassing a whole bird, just parts and other glassing projects. But I have become a good glasser! All I want is a great surface for paint, as Edwin stated early, just need a good painting base. I got some more work done on the fin and ruder, all my hinge blocks are in, and my hing blocks are glued up. I am finding that I really enjoy using the yellow glue on this build. I have been impatient in the past and I was addicted to the instant CA glue, but now that I have kicked the habit I am really liking the glue it and let it be till the next day method.
Next on I will glue the LE on the fin, sand and start on the hinge pocket.

So just a little off the current topic. I was looking at engines for this bird and I have a two year old broken in DLE55 slated to go in this bird, but I have also been looking at other options. The new DLE85 has my attention and well who doesn’t want a Moki. I have been toying with the idea of using the Moki 100 twin. Same HP as the DLE55 but you get that great four stroke sound and look. The Moki is just over 10” from valve cover to valve cover so not sure it will fit in any orientation. But it is still on the board for consideration.

RE: Top Flite GS P-47 sports scale; diary of a build
Tony the DLE is a sure fit in this plane and with a Jtec in cowl muffler you can get the whole thing in the cowl and not cut up the sides. I think I paid $110.00 for mine, just call Jtec and order the in cowl muffler for the 1/5 scale mustang, it's a perfect fit.
Check mine out, made a beauitful front end and you gotta like that look.

Nice mustang Leroy, maybe I will build that next! So are you saying the DLE85 is a perfect fit or the DLE55?
My elevator torque rod hinges came today from Tower, so I’m headed to the shop to install them and maybe glue the carbon fiber joiner tube in.

No, especially if you want it in the air in 3 months, and not to mention the "burn out factor" goes way up when you start doing that stuff. If you manage to get through it though, you'll have something at the field that few others have, and that almost makes it worth it.

Tony I'm going to guess your planes weight to be between 25 to 27 lbs when finished and the DLE 55cc will haul that around with ease and very scale like. The 85 is over kill for that plane however it's a good choice for 1/4 scale. Several guy's are useing the DLE 55 in mustangs weighing over 27 lbs, a 70CC engine would be about as big as you would want. All that is based on popular choices for planes your size and expected weight. Leroy

RE: Top Flite GS P-47 sports scale; diary of a build
Leroy, Your probably 100% right on the engine size. I have a “wait two to three days” before I do any major decisions on this bird in place. I have a perfectly good broken in engine siting in my hanger. So it will sit a bit longer. I have been also considering the new rear exhaust DLE55 or even the twin 60 (if it will fit). So the motor can sit as I continue to build. Thanks for the input, that is exactly what this thread is about!
Back to the build! I spent a couple hours in the shop this evening working on the ruder and fin. I did a few things different then the plans. First I could not even understand how the jig was suppose to work so I made my own. I took the two jigs and glued a base and a 3/8 block to each. I also used the 3/8 block to keep the TE of the fin and the LE of the ruder in the right spacing. I pined down a block at the bottom of the ruder to keep it solid and in place. The jig fits in between the TE and LE and you can pick up the assembly and move it around, then set it back on the flat surface. So much easier then the stab jig that has it bolted down in one place, cant wait to be done with that thing.

I gotthe fin and ruderall rough sanded and I glued the LE on the fin. The hinge blocks are ready and all I need to do now is install the tube and hinge the ruder, that might happen tomorrow.

RE: Top Flite GS P-47 sports scale; diary of a build
As mentioned earlier my elevator bearings came in. So I spent most of the evening thinking, fitting and designing the bearings. All in all they came out better then I thought. I made up a couple carbon fiber bushings that will act as the bearings. Once I have it all worked out I will glue them to the carbon fiber joiner tube. The bearing housing is aluminum and has a 4-40 threaded post at the base that will be glued into the TE of the stab. This will happen on final installation of the elevator and ruder.
I was in build mode so I did not take a lot of pics, I was on a roll so I went with it! To make the bushings I first drilled a ½ hole in a piece of 3/8 ply. Then I inserted a ½ long piece of the carbon fiber sleeve. I clamped a piece of ply on the back side and sanded down the carbon fiber tube on the belt sander. This gave me a perfectly cut bushing.
I decided to not glue the elevator joiner tube in quite yet. I want some more time to go over the order of things and how it will all go together. I am not sure if I will paint it all or just some parts. I am thinking of just painting the carbon joiner and leaving the rest natural. We will see.

RE: Top Flite GS P-47 sports scale; diary of a build
Tony I must have had a mind cramp when I posted those pictures of the mustang, forgot your's is a P-47 for a moment. An RA engine would be nice then you may be able to add some turn out angles to discharge tubes to get exhaust out the real location.
Pretty cool, the bearing housing looks like Robart strut door arm mounts, gotta like a guy who's always thinking. Firs time I seen that done, great idea.
Your doing a great job and making good time too.
