REAL? sawdust? it must have taken a forest to generate all that. and a mess when the wind is up. Using it as fuel is and intelligent move but someone will find a reason they can't continue the practice. isn't it also used to make particle board?
I save sawdust and use it as filler when mixed with clear dope or white glue or packed in a hole and hit with ca. The local officials here wanted to use cow chips from feed lots mixed with coal to burn in a power plant but it was nixed for some reason.

I think this dust maybe too fine for particle board. I know Sauder claims they use over 90% of every tree harvested over the industrial norm of little over 50%.

On 29th April 1917 a man with the same name as me was shot down and killed by Baron Manfred von Richtofen while flying an artillery observation flight in a BE2e. I hope that people will not think that I'm excessively sentimental but I plan to fly my 1/6 scale BE2e later today as some kind of tribute. Weather permitting.

100 years ago, it was very risky business to fly. A new development, incendiary machine gun rounds were developed. Doped muslin cloth is very flammable. A hit at altitude was a sure path to a flaming death, a boost to kill ratio. No longer did one have to hit the gas tank, engine or the pilot. There were no pilot parachutes. Cockpits were not armored with any type of ballistic material. It is no wonder that the phrase, "Iron Men with Wooden Wings" was coined.

My namesake was particularly unfortunate because he had been with the squadron for over four months and pilots with that length of experience usually survived their tours. Mind you he was up against the best fighter pilot of the war! His aircraft was too slow to outrun the German fighters, too stable to out-fly them and too badly armed to defend itself. This was exacerbated by having the observer in the front cockpit so that to return fire he had to fire above the pilot's head. The aeroplane fell between the lines and was fired on by the artillery of both sides. Neither his body nor that of his observer was ever recovered.

It's a glorious morning here which promises a good flying day. My sister and brother in law are over for a few days holiday. They are paying me a visit later today. Fortunately they are both very house-proud and my domestic arrangements do not come up to their high standards so they are staying in a hotel about twenty miles away. That's not clean enough for them either!

I'm "Shotgunning" my approach to obtain detail on the Grumman F11F1 which never saw combat. I have wanted to get close up and functional details of the front slats; flaps and top only ailerons. Built primarily now in the 1960 era and information for the rc modeler is hard to come by. I built a terrible representation when eleven years. I always wanted to build a "stock" representation for free flight with an .049 single cylinder spinning an aluminium fan for "power." Not a dynamic model but one that captured my young mind. I can no longer drive long distances so visual closeups are probably not my answer. I just want to hang it from the ceiling and admire it done the way it supposed to be.

Now Lithium Polymer power and production brsthless commercially made and balanced EDF (electric duct fan) planes are common and powerful. Only a notch down from fuel turbine powered jets. In addition to the plane as designed by the Berkeley Model Kit Company (now defunct), I want to throw my hat in the ring building. a respectful model with small "Park Flyer" small space radio control model attributes as # 2. I am well versed in rc control of prop two and four stroke models ranging from 25" wing span to a (for me) exhaustive but satisfying 98" P-51 D model.

This "Tigercat" is a project not obsession but with limited engineering training and the creek "don't rise" I will incorporate functional detail. I need someone very familiar with the "cupping of the swept wing for slow flight. We leave few footprints in the sand when we go. This plane won't deepen my prints in the sand but my great grand-children might set down their cell phones and even be sparked by things balsa that fly represent history and are just plain pretty, no,,,beautiful.

I need any sketches, verbal descriptions; rough dimensions, anything I can learn from and emulate. Modelers, crewman, crewman that model, engineers, walk around photos. Anything I can get or learn. I want to see how the slats are deployed. I want to see how the flaps were deployed and looked like when helping the wing lift better at slow speed. I want to see how those darn ailerons on top only were lifted and worked.

My <[email protected]> is good and so is (817) 578-4297. 213 Bahama Ct. Granbury, Tx. 76048. My name is Kep.
I really need your experience, memories, photos. stories, and anything to help me shred a little balsa. Thanks

I have the same desire but not the time but I have gathered some info do you have a set of plans? if not go to the outerzone plans site. Then do a google search for pictures of the f11f there is plenty to look at.
stay in touch I would like to see your progress.

I just saw for the first time the wing tips fold down,.............now that's a change from the norm.

Unfortunately it was too windy for a memorial flight yesterday. Next Wednesday seems possible.

I concur! It would be a easy plane to build and would make a terrific turbine bird. I only wish the time was available to me so I could build one and several others.

Back when I was a young wiper snapper and working for working for gen/dyn, Convair in SD, Ca they had just flown the original delta wing F102/model-8 and it would not go supersonic so we built a some model's for the wind tunnel with several of the hour glass shapes, found it would go supersonic with out after burner, and boy did it pick up speed in A/B.

Just an old geezers memory

Back in the early 1980's I was a young whipper snapper too, ran the data system on wind tunnel tests for the DC-9 boat tail tests on a 4' wind tunnel model at the Rockwell blow down wind tunnel facility in El Segundo. We were using the newer quartz transducers instead of scanivalves, so us Douglas types brought our own portable data acquisition system, Tektronix 4051 on GPIB buss. The transducers were quite faster and we could scan all ports at a shot during scan, so they'd pitch up the model continuously instead of stopping say every 5 or 10 degrees and hold as with scanivalves, done with all scans in two days. (Scanivalves had stepper motors that would switch to a different set of pressure ports to take readings, so say after 6 - 8 steps all ports on the model was scanned.)

In the latter 1980's, those chisel type boat tails (the cone on the back of the fuselage) on the DC-9 variants MD-80's, 85's, 90's was a result of that wind tunnel study, produced less drag in flight than the traditional cone.

It's amazing how much difference a small change can make. Look at all the new airliners using winglets on the wing tips, that little up turn tip makes a huge difference in economy.

Rockwell blow down wind tunnel facility was interesting. It had 6 huge spherical storage tanks outside. Huge compressors would pump the tanks to 6,000 psi of air. This would provide up to around 5 or 6 minutes of air in up to the transonic region. It was called blow down because the tunnel didn't have a recirculating loop, like you see with other wind tunnels at say, NASA's Langley. The wind tunnel model was gorgeous, machined and assembled out of aluminum. Small stainless steel tubes were set machined flush at the surface. Channels cut to route tubing on its surfaces were filled with a JB Weld like Epoxy material, which was finish milled to blend with the surfaces. They had a set of about 8 boat tails, would do several runs on one, then break down and bolt on another. With our short runs, they'd do a couple blows, then while compressors were recharging the tanks, swap out boat tails.

So power hungry were the compressors, that during the summer, we ran at night. During winter, we ran at day. If we went over the allotted hours, the utility company or government would fine Rockwell $20,000, I can't recall if this was per minute over or what. (That was 35 years ago.)

The study of induced aerodynamic drag is a fascinating subject. I believe we have only begun to understand it and many more changes is in the future and will not necesarily be discovered by the government. I believe Burt rutan came up with the wing tip idea on his own, he is a fellow modeler also.

Today aerodynamics has been the topic of conversation for the second time this morning and I am enjoying it. was the t-38 and f-5 the last to use the coke bottle fuse? I think the russians never used it.

He's a great guy as well. I got to see him speak at University of North Fla and got to speak with him for a few minutes.

He is most concerned about getting youth excited for STEM careers.
