Do you unduhstand, old man. Another issue to consider is the appearance of "self forming" joints during testing. Thus a more advanced form of joint testing was needed. The use of plywood-style pieces of balsa was not tested, but it needs to be considered. Failure was determined to occur when the joint either snapped or would not hold any more load.
I hope to be flying a 30" Micro Bird with electric power in my backyard soon and the free flight version at the AMA flying site this spring. Hold the remaining ribs in place, apply CA and firmly hold each rib to the rear trailing edge bottom sheeting until the CA has cured.
Using transparent Monocoat allows the sun to glow through the 11 foot span beautifully. Sample Torsion Specimen In general, the material failed at the spaces with the smallest cross-sectional areas, where imprecisions in cutting took place or the material was simply weaker.
Although it is doubtful that this would be a part of the design, it is important to take this in to consideration in the design, and hopefully take advantage of this type of behavior. Several bridges have collapsed due to high speed winds.
The final structure will consist of only balsa wood and glue, thus the choice of glue is a crucial decision. Both the Wood Glue and the Epoxy both were stronger then the actual wood, and the wood broke before the glued joint did.
You do this after you determine how much weight is required to balance and then weigh the pellets out before mixing in the epoxy. In the actual design, the glue will mostly be under shear, notably when used to ply several layers of wood together.
However this test yields comparative results for each glue and has an obvious best solution. Sand the fuse corners, nose block area and canopy. Glue formers F1 next followed by F5 and F6 and then F8 stab mount. This gradual change in grain will be possible with plywood style layering of the balsa.
The finger joint is likely to have failed because it has the most area under shear force and as stated earlier, glue is weaker in shear than in normal stress. I am working on a 50 incher and a P Class rubber free flight version of my great Lil Bird 2. Figure 7 shows a basic design.
And then tragedy struck — we ran out of stock footage. It was apparent that a decent percentage of the design. Glue the tubes in with epoxy. Yes, thees time, we can pay the bill, okay. Uh, we at Amtrak would like to apologize for any inconvenience it might have caused… This rarely ever happens. Joel, CrowServo: I use a Perma Grit sander becuase they sand so much quicker than sand paper on blocks.

In April, the design will be tested against. Balsa wood is available in inch and inch lengths from most local hobby supply stores, but for the quantities used for a class of over thirty students, it is best to either order the balsa wood.
