I could post images of DF furring strips I've selected from home depot with grain much closer than aircraft grade spruce and grain slope that meets the criteria but there would be no point.

Blanks intended for longerons and wing spars used to be aircraft "certified" Nobody wants to stick their neck out anymore. Yes, most lumber found in lumber yards is fast growth intended for general framing. I think I mentioned in an earlier post that Furring strips made from close grained...

I figured I would get resistant comments. That's what a forum should be about, constructive criticism. I'm not asking anyone to agree. Even though I claim to be a cheap ass, I'm really just advocating for reasonable cost as compared to the unreasonable prices of so called certified Sitka...

I don't understand the "Money" comment. If I can afford 16K for a new composite prop, why am I whining about the high cost of aircraft grade (un-certified these days) Sitka Spruce? I happen to not revere throwing money away if there is an alternative path.

Not triggered, but now I'm taking my toys home.........

What is your issue with the MT prop? My point was the composition of it's construction and not the cost of it and not whether I can afford it though certainly my cheap ass nature is the reason I can afford it. Without a doubt the current times with the economy and supply chain issues, there...

Ya I've seen that demonstrated in Velocity aircraft but I would imagine if the aircraft is too slow, card stall recovery would not occur hence diminished pitch control. I suppose the deployed spoiler did not help either.

Innegra impact test. The sample is one layer of 4oz Innega laminated on each side of 2lb density extruded polystyrene foam 1" thick. The hammer weighed 55 oz on the head end. Notice the groove in the laminate sample where I folded the sample multiple times.

I think that is way cool! I really like the Pietenpol design except for the cockpit access at my age and frame size.

I have zero experience in this type of aircraft, only information found online. To my understanding the angle of incidence on the canard is set to a higher angle than the main wing and is intended to stall before the main wing resulting in an automatic nose pitch down stall recovery without any...

I've never seen hem fir plywood though I imagine I'd like it. Too bad there are no plywood mills within a thousand miles of my location. Far less likely to spin. 1,000 FPM mush.

Ya, will somebody please light a fire under the butt of one Mr. Wainfan and his solution to this problem the FMX series............

Ya....I tried that once when I was a kid. That is I fell right into a Cholla Cactus. Boy did that suck. I wanted to die.... I see you are interested in Model A powered Pietenpol, is that not an example of making use of something more readily available? That is, once upon a time, the Model A...

I suppose this conversation could go on for some time. I think we were discussing what could be done to a wooden aircraft fuselage in order to reinforce it to include a "safety cell" for the occupants. Wood can splinter for sure. Aluminum can crumple for sure and it also likes to fatigue over...

And the Bigger manufacturers like Boeing are now heavily substituting aluminum with composites........

Oh ya, I missed the nose gear still retracted.

Landing went bad but go around aborted too, perhaps engine issues? Pilot must have decided he had no choice but to put it down but was too slow which likely resulted in the Canard stalling before the main wing (intentional design parameter) hence the loss of pitch control and inability for the...

That's a great idea. How about we also fill up the cockpit with packing peanuts before each flight. That would provide an additional measure of energy absorption before ones body impacts the interior of the fuselage. Ha, ha.......... Seriously though. There may be something to all that...

Exactly! Well sort of. It's entirely possible to build a pure synthetic composite VP-1 or VP-2 but probably it makes more sense to build an already proven all composite design? For me the VP attraction is the slow flying nature and simplicity of construction and most especially I like the...
