Scale Build-Off 4: 48 inch Stearman by Aerodrome RC

I ordered a Stearman short kit from Manzano laser and was very pleased with the quality.

I started with the tail surfaces. Construction of the elevator and horizontal stab are straightforward. I cut the stringers from sheet balsa with a stripping tool. Just regular wood glue. nothing exotic.

I also laid out the rudder and vertical stabilizer.

One piece to watch is S13. There is an S13 piece that is 1/8 inch like the rest of the frame. The plans have a lamination with a 1/16 balsa piece between to 1/64 in ply pieces. The lamination seems to make the separate 1/8 in piece unnecessary.

Make sure to line up the lamination correctly to leave room for the tailwheel wire later on. I think the pictures clarify what I am saying.

The laminated parts for S13 were a later addition and I just forgot to remove the old S13 from the cut file.

I like the change. The lamination sure makes the rudder control horn mount much stronger for virtually no weight change. And I think the tailwheel strut gets bent in there, making the tailwheel steerable. Nice.

Fuselage construction has begun. I use regular wood glue to give me plenty of time to make small adjustments, using my builder's square to ensure everything is perfectly vertical and aligned. For the plywood former supporting the landing gear, I used 30 minute epoxy. That may be overkill, but better safe than sorry here.

It helps to sand the slots in the formers so they slide smoothly on the side keel. Alternatively I could have sanded the side keel a little.

I started with the center keels, top and bottom, and the formers on either end and the center keel. Once those were dry, putting the other formers in was easy.

I remembered to install the blind nuts for the saddle clamps needed for the landing gear. That will be easier than trying to install everything after the former is glued in place.

Frank, I couldn't agree with you more. I am so happy her models are still available. My Pfalz DIIIa flies so well it is ridiculous. And NOBODY else has one at any of the clubs I've belonged to.

Am I missing something? I don't see an active build for you. Taking a break?

I finished the fuselage for now.

I took the left half off the building board and installed the ply riser. It went in easily, a great fit.

After that dried, I built the right half slowly. First just the two formers that supported the front and back ends of the riser, and F16. After they dried, I installed the riser and let it dry in place. Then I installed the side keel and the rest of the formers.

The design is really great. Everything came out nice and straight with little effort on my part.

I will figure out what I am going to do with controls and radio equipment before doing all the stringers.
