There are no good photos I can find of 14V dash but I know it's a two cockpit airplane. It looks as if the rear dash is cut down so it is unknown what resides there. I doubt the dash was laid out original but I tried to come up with something similar to the time period he flew the plane. I got a set of graphics from Callie Graphics which are very nice but the dash does not exactly fit. I think the fuselage in the Hostetler Chipmunk is a little wider than scale. That's all fine. I am not going after a master class plane here. I came up with graphics and laid out a dash. I 3d printed some parts.:

I threw the 3d files and print file for the dash here if anyone want's it:

Next I am working on 3d gear fairings:

BTW, I did not like the way the plans lock the wings. I can see the spar getting mashed, split and continually being a problem so I drilled and tapped mine 1/4-20. The forward bolt goes into the landing gear block too:

Finishing the wing fillet's took a little time. The rear section is light ply, the center section is actually cardboard. The front is expandable foam brushed on then carved (yes I mixed too much). The fillit is then covered in fiberglass cloth using Z-poxy. Sanded then skim coat of auto body filler to smooth then auto body polyester primer for final smooth sanded 400. Painted with Rust-oleum primer then white. I think they came out pretty well.

WOW..
What a freaking mess.
That is certainly not a project for the spare bedroom...

But, a cool idea on how to do it.
In the end the finished product makes it all worthwhile.

The foam wasn't as bad as it looked. A saw took 80% off. 40 grit sand paper made short work of the shaping.

Covering process. Covering round airplanes

a lot easier than slab sided airplanes......NOT!

Tony Hallo

What are you covering with?

My Feedback: (1)

Most is Monocoat. Some of the white is Neucover. The colors I got from Neucover were not what I needed so I will use them for something else. I think I like the shrink on the Neucover just slightly better.

For adhesion, on the control surfaces I use a dusting of 3m 77 spray adhesive (or any average spray adhesive, not the super adhesive). It is what I prefer but it was easier to brush something on the Fuselage. I can't get Stik-it any more or Balsaright. I got cover Grip from Horizon hobby. It's like thinned down Elmers Glue. I am using it but will find something else next time.

I toyed with Fiberglass or iron on. Initially I was going to fiberglass and paint. After mulling it over I decided to get it going at first with Iron on then see how the weight is. I can redo it later.

Not nearly as much fun as tapered checker boards (parallelograms)
But tedious none the less...

Your Plane is looking good .

Would any of you fine people have a set of the Don's Custom Models 100" Super Chipmunk plans they would be willing to part with (or copy)? I picked one up yesterday but with no plans, clear canopy or rudder. Rudder is no problem, Plans aren't an insurmountable problem, but i would like to have them. Canopy? I have the means to make one but it would be an effort to make the plug.
Any help appreciated.. BTW, I had a Goldberg Chipmunk in the late '80's- early 90's and I put more hours on that plane than on any other plane I have had before or since. Sweet plane to fly.

I believe a fellow that goes by the name of frequent flyer is selling that plane again.

Getting the canopy on took some time. Not my favorite part of the build. The canopy needs to be removable for access to the inside of the plane. I have seen some people glue the canopy on and then make that section of the body removable. I really did not care for that. On the flip side, for a sport plane I was not going to the trouble to make it slide. The first thing I did was make new bows for the canopy. The ones included in the National Balsa cut kit were not close to the fuselage width. I set up 2 bows with doll pins. The forward part was cut and #2 screws used to help hold it in place. Small hard wood blocks glued inside the fuselage where the screws are. Originally assembled with Gorilla glue and socket head screws to help the process. When the glue dried, the screws were swapped for small head Philips.

The rear canopy was screwed and glued on as well:

The rear plywood canopy arch was not even close. I glued in hard wood dolls, drilled and tapped them 1/4-20:

Side rails added with a rear doll pin to keep the sides from bowing out. A slot was made so it can be removed. A front hole was drilled in case I needed it:

The canopy is rock solid and simple to remove with 2 screws. For a simple sport plane I am pleased. Pilot is 3d printed but needs to be finished.

Welded scrap steel together for engine stand. Table is on wheels so I will need to strap it to my truck.

RICKSTUBBZ

Sure is looking nice!

I bet there are not very many people with an engine test stand like that one.
