Hostetler Stinson SR10 Build
Going to be building the Hostetler Stinson SR 10. Just received the cut full kit from National Balsa yesterday. Had a question about stab, elevators and rudder. The plan shows these built with 1/8" balsa laminated with 1/64" ply. National Balsa sent me these parts cut out of 3/32" ply. Not sure if these are templates. If they are tempates they didnt send me 1/64" ply. Could i just use the 3/32" ply parts? They would be 1/16" thinner than shown on plans. I plan on asking National Balsa Monday but wanted to see what everyone here thought.
May try to turn this into my build thread but not sure there is an interest since there is already a really good one on this site.

Go ahead and use the 3/32 parts.
When I built a Hostetler design, I purchased a kit from a different cutter. I found a few substitutions, in parts thickness, or the way that they cut. It all ended up fine.

The drawing shows a single layer of ply in the thickness center and is not drawn as a ply.
I realize the impossibbility of printing 4 lines at full scale having 1/64" total thickness.
Your total thickness is 8/64" + 1/64" + 8/64" = 17/64"
Using the 3/32" instead of a 1/64" give a thickness 5/64" thicker.
I would use the 3/32" ply and enjoy more strength.

Tom Crump has experience with building several large-scale models including Hostetler's designs. Go with his experienced advice.
I took out my copy of the Hostetler SR-10 plans. I see what you're referring to. The core of the vertical stab, rudder, horizontal stab, and elevators show a 1/8" balsa core between two sheets of 1/64" ply. 1/8" balsa ribs bring the profile of the surfaces to meet the outline as shown on the plans.Not sure what type of 3/32" ply National Balsa sent you - aircraft-grade ply (typically 5-plys) or Lite ply (3-plys). My money is that you have Lite ply. I missed the part where they sent you two sets of the ply parts for thevert. stab/rudder and the hori stab/elevator(sarcasm intended).
To settle things in your mind, lay out the vert. stab/rudder ribs (R1-R5) and the hori stab/elevator ribs (S1-S6) onto your plan sheet. If the gap between each pair of ribs is 3/32", this is an area where National Balsa made a substitution. No big deal.
By all means post a build thread. Lots of folks learn new things from build threads. I know I do. When it comes to advice, go with those that have experience - not speculation.

RE: Hostetler Stinson SR10 Build
The 1/64" ply skins on the 1/8" balsa sheet core approach on the plans would be a bit more stable than the Lite ply, but the 1/8" balsa ribs and leading/trailing edges will stabilize the Lite ply just fine. If it were me, I'd build the rudder or one elevator panel, un-sanded, and set it aside to convince myself of the stability of the Lite ply. Then I'd have my answer as to if I'd stick with it or make-up the 1/64" ply/1/8 balsa sheet core pieces.

RE: Hostetler Stinson SR10 Build
Ya, I'd like to see a build thread, too. There are plenty of experienced giant scale builders on this site. I'm sure that many would be willing to help, if needed.
If it bothers you, go ahead and laminate some 1/64 to both sides of the ply core. It sure won't hurt anything.
It's all about feeling secure in what you are doing. You don't want to build this big, beautiful, masterpiece, and be worried about it's construction.
I frequently modify things to what makes me comfortable. I always err on the side of strength, just to make myself feel better.
Your airframe will be handle some extra weight. Don't go nuts, but build it so that you are secure with the construction methods.
My Hostetler design required careful study of the plans. Make sure that you have thought out at least two steps ahead of where you are building. You want to think things through.
I'm green with jealousy. The Hostetler Stinson is a model that I would like to build. I already have a SR-8, however. It'll have to do.
Here are pics of my Hostetler Cessna 195, and my IKON Stinson.

. So far not a good start. Going to call National Balsa hopefully they will help me and take care of this. Iwill turn this thread into my build thread and will post some pictures soon.

RE: Hostetler Stinson SR10 Build
Unfortunately, missing parts is not uncommon.
I find it easier to pay the local hobby shop a visit, and buy what I need.
Unless it's something major, I prefer to keep my builds moving, instead of waiting for $10.00 worth of materials to arrive.

RE: Hostetler Stinson SR10 Build
True, have to pick your battles sometimes. Waiting on a part that would take 2 minutes to make might not make sense. The quality of the wood is great.

RE: Hostetler Stinson SR10 Build
Thought i would give an update on my build. Received all the missing parts from National Balsa. They were great and responded quickly. Started with the tail components. I am expecting my second child any day now so my build time has been short and far between. Below is my progress:

Looking at the fin-rudder picture I cannot see the hinge line as appear on the drawing to the right of the balsa structure. ????

Tom C and sctriguy,
First I wish to thank Tom C for his post. His posting gives me more reason to have doubts about my monitor rendition. I see in some of my pictures some monitor colors that appear bluish when I know for a fact that the color is green being pics of my own model.
Explaining my post #15 I see a balsa colored single vertical balsa colored leading edge of the fin and immediatly to its left a dark black line that I interpreted as a shadow of the balsa piece as if the illumination is coming from the right. I do not see any hinges likely not yet installed.
I will now guess that the wide black line is perhaps a carbon fiber trailing edge of the fin or I do not know why it is black.
I will attempt to take a picture of my monitor screen and see if that is possible.

CONGRATULATIONS on a job well done.
Not only the fin-rudder but the arrival of a beautiful baby girl.
Best wishes to you, mom and baby girl.
In no time at all you will listen to Mama and Dada and look at a pretty face smiling at you.

RE: Hostetler Stinson SR10 Build
Good lucl with your build, I also recently purcased the Stinson reliant kit from National Balsa, also was concerned with the ply fuse sides they sent as a substitote, Icalled Hostetler about this and was told it would be O.K. but to line the top and bottom of the fuse sides with 1/4" Square balsa for added support. my Kit was also short 1 sheet of ribs for the verticle stabilizer. National Balsa sent me the missing sheet and also 1/4 inch balsa to support the fuse. I have used national Balsa for other project and they have always been very helpful and quick to respond to any issues. My build is under way and going smooth,I would post some pictures but I'm very lacking in computer skills. It would be great if you kept the thread going

RE: Hostetler Stinson SR10 Build
Sorry the pictures don't show, don't know what I'm doing wrong. have the horizontal and verticle stabilizers and the basic box of the fuse all framed. parts F-12 did not come from National Balsa with the arch cut. I will see if I can get some help with the pictures
