Don't be. You've picked probably the hardest design to build, from scratch, by hand, and documented & shared every moment with complete strangers. That respect has been earned, and I'm sure everyone will agree.
Now stop surfing and build those plugs!!

Thanks for the reminder at the field Sunday. I finally dropped in for a look. Shoulda done it sooner but I new I'd get sucked in for more than a few mins. Nice job and now when we chat I can see what you are doing in me mind.

Hello Wayne:
The shoulder is still giving me trouble. Strength is an issue, but that will come with therapy. At all costs I am trying to avoid another surgery .

As to the talent.....well I don't know about that really. It is more planning and taking the time to just do it. I have started to do some work on the Bell 47 to get it ready. The muscle spasms are getting better, so maybe early winter she will fly .

I have ordered some 3/4 once fiberglass cloth to finish the Cheyenne fuselage plug; should be here today or tomarrow. I am looking forward to the detailing and mold making.
Richard

Great to hear the shoulder is getting more "bearable" at least ! Its truly amazing what PT can do for you. I recently had PT for shoulder impingement and it is about 100 % now.Glad to hear progress on the 47,you are going to LOVE that big bird!! When you get ready to fly maybe we can run up there and give you some moral support. Wayne

Hey Richard,

I'm a former Debbie's RC groupie, now I live in Charleston. Moved away in 2007. Anyway, I'm very impressed with your skills and this bird. It is really looking good and I can't wait for the mold making.

I will be up there this weekend so I hope you can come out to Debbie's on Sunday so I can meet. I use to fly with Joe and Don. Keep the pics coming.

Here are a few pictures of the detail work begining on the Horizontal stabilizer. I made a small tool to create screw heads in the almost dried primer that was masked and sprayed on for making the panels. The tool is simply a jewelers phillips head screw driver with a piece of brass tube slid over it that has been sanded down on one end. Then it is cut to length so that when you slide the tube over the screw driver the tip protrudes just enough to create the impression of the screw. Also for dzuts fasteners, just use a flat screw driver in the same fashion. Any way this what it will look like.

These should show up nicely on the molded fiberglass part.

I will try to stop by the field Sunday.

Work for today: I will be glassing the wings today and turning the forward gun turret on the lathe. Pics to come.

Okay Butch:

I'll bite, If the that little screw head tool is the second coolest thing you have ever seen what would the first ?

Cheyenne build update:

Well I managed to get the wings glassed, smoothed and primed, and they are now ready for detailing. I have had several pm/emails asking how I finish out the parts after glassing. So here is the complete process I use....


After the fiber glassing was done (again using the paper towel method)the glassed surfaces were sanded smooth with 100 grit paper "dry" to prepare it for the skim coat of Nitro Stan red automotive filler. (Using the paper towel method will prevent too much resin build up whether you are using Epoxy or Polyester.) Remember not to use too much pressure while sanding so you don't sand through the cloth. If you do sand through just wet it out with medium CA over the damaged area and rub it in with your finger.


Here you see the skim coat of Nitro Stan that was applied with a squeegee. I prefer to use a piece of 1/8th inch balsa sheet that is cut to about 2" x 1".


After the skim coat has dried, it is then sanded smooth; again using 100 grit paper "dry".


After sanding, any noticeable flaws are touched up with more Nitro Stan and then sanded smooth for the last time with 100 grit paper followed by 220 grit paper both "dry".


Now the first coat of primer is applied and when dry; is sanded with 400 grit paper "wet". Then if any other flaws are revealed by the primer, again touch it up with Nitro Stan. (If you have been careful there should be very little Nitro Stan needed at this point). It should be getting very smooth now.


Here you see the 2nd and final coat of primer after having been “wet” sanded with 400 grit that was then followed by 800 grit paper “wet”. The surface is now dead smooth and ready for detailing or painting.


This photo shows the canopy plug finished and ready for the color coat and polishing. This plug will be used to vacu-form the clear glazing’s.

That’s all for now!

I've come up with some ridiculous stuff, but that has to be the most deviously simple thing I've never thought of. I'm sure my Apache needs some screws and dzus fasteners somewhere...Keep thy head speed up, less the earth come up from below and smite thee.

Great progress. I really love watching a guy with this much skill scratch build stuff. I'm a decent builder, but this level is just plain fun to watch. Unique aircraft too. Been watching this since day one!! Keep it up.

I have received a few PM's and such and was asked what exactly is "Nitro Stan". It is actually a name brand spot glazing compound, and there are other manufactures as well. It is essentially a thick Lacquer. It comes in a tube as well as cans (I like the tubes), and is used to fill small, shallow imperfections. It requires no mixing, and it dries very fast.

Here are couple photos of two manufactures versions; both are great. You can also get this spot filler in an acrylic.

Great info Richard. Just for kicks, take a look at Teans gallery, he's got an old Schluter photo spread.

Looking forward to seeing the canopy come together.

Hello Patrick

I actually sent him a PM asking about getting a copy of the plans. He said he would look into it, but I have never heard back from him since????

Plans would be a nice addition for documentation; a little research dug up some shots of the old Monogram 1:72 kit from years back:

Looking forward to your progress. Any decision on the tail drive??

Hello Patrick:

I had not seen those pictures before. Did you find those on Hyperscale? Who ever built that model did a nice job on a really bad kit. Even though Revell/Monogram got most of it wrong it still looks like a Cheyenne!

Here a few pictures of the Cheyenne. The fiberglass work is done, and now I am doing the filling, priming and sanding portion. The glass turned out very smooth so it is going pretty good. Because of the size of this bird I am prepping it in sections. When I get that done I will give it a final overall coat of primer. To ensure that I get all imperfections filled, I will go over the Cheyenne with a bright light held at an angle to the surface. Any remaining flaws will show up as a shadow and will be spot filled. Then on to the detailing.

Richard
