    Raptor Composite Aircraft

    Wasabi learned their aircraft was uncontrollable with one engine out. Everyone under the same circumstance would have crashed. They might have been able to save it if they could have cut the running engine in a safe place.

    Are tube spars an insult to the engineering community?

    I don’t think anyone disagrees about the best engineered structure would be the I beam. It also requires someone to execute it during the build. That does cut out a number of people. Lazy or not comfortable building it. The round spar brings them back in to a possible builder. If you are...

    Are tube spars an insult to the engineering community?

    Building a tapered composite tube spar is fully left field. It has the complexity of designing any other composite structure but leaving the usefulness on the drawing board. It’s not simple anymore. Super complex with out any of the easy of pre fabbed off the shelf stuff a tube spar is...

    A practical UL trainer....or not?

    It is and it isn’t. You are still on your own when you step into a UL but you know the reactions. Learning the drag curve is the hard part with a transition. No one should think it’s going to be the same. I know someone who with 90 hours of 150 time went and bought a single seat Pitts and...

    A practical UL trainer....or not?

    No. I’m saying that it’s a bad short cut. No matter what, there is a way to get real duel. I’m saying this to a candidate, if you want to fly this single seat plane, go get training in a 150, Cub, or B-52. If you really want it, suck it up. You’re life is in the line. I don’t want to spend...

    How did Beechcraft get those butter smooth controls ?

    Part of the art of this is perceiving the strength in moving the controls. Moving ailerons, stick or wheel, is using a weak strength position. Elevators is a stronger position; more natural motion. Rudders have a lot of muscle behind it. The hard part is making all feel like you are giving...

    A practical UL trainer....or not?

    I find that the RC people that learn with the crutch of stabilization electronics tend to want the crutch after. Mostly older people. It’s very hard to convince because it’s instant gratification. Most people will not push beyond because they think they conquered the task. I was watching...

    Raptor Composite Aircraft

    I mentioned the PIO, because from the ground someone might think it was a stall instead of a pilot chasing his tail, or nose I guess.

    Are tube spars an insult to the engineering community?

    My mom could probably put an original BD4 together. It was designed for the person who’s tool box is in the kitchen drawer, a claw hammer, a Phillips, and a lost straight slot, in there with the pruning shears and a bunch of old mail. Simplicity is hard. It was never meant to be end all be...

    Raptor Composite Aircraft

    The first time I saw a Starship take off in the wild, the pilot PIOed. I figured it was someone in the right seat.

    Aircraft *designs* available for sale?

    Personally I prefer a Delahaye but would put up with a Delage.

    Grounded!

    Good job on paying attention. Smart to fix it. Sounds like you might have lost the alternator

    Raptor Composite Aircraft

    I think Velocity is trying to lend a helping hand. They would rather have competition on merit not elimination. I don’t think PM can accept on ego. True fight test program. No. I bet Wasabi would fly it out of Valdosta. At least once. It’s much better than the original Airport, which...

    Are tube spars an insult to the engineering community?

    Elegant engineering. It all depends on the solution you are try to engineer. Bede had one thing in his mind, ease of building. An AA1 wing panel is a spar tube, 5 ribs, 6 skin panels, cove, and a wing tip. Yes you still have flight controls, identical flap and aileron skins and end caps...

    How did Beechcraft get those butter smooth controls ?

    They knew what they were replacing; they knew it was a high end aircraft. It was right after WW2, lay people knew if someone called a plane a dog. There was a lot in the line. The Bonanza is probably the best overall, but a Viking flys sweeter.

    Narfi's Scratch Built Zenith 750 Super Duty

    Beats finding 100 gallons of blue juice under the floor. At least it was un-used. At a regional I worked at, they had to reskin the whole side because of lots of corrosion found during a repaint. Bad enough that the plane went back on line and was made last plane to go in. Had to be fixed in...

    FAA written exam / gliders

    Written is about memorizing and regurgitating. Some like Gleim I like ASA. Mark the ones applicable and learn them. It’s the way the system is designed. Skip all other questions. Oral is different. FAA knowledge book. Medical topics, weather and FARs will be asked from that. Good...

    2020-Sept 20thReno Racers:

    F1 needs to be split into traditional Cassutt like Hershey style wings and tapered high tech. I bet more square wing planes would show if they knew there was a chance.

    Narfi's Scratch Built Zenith 750 Super Duty

    Is the corrosion because of ocean proximity, or spilled coke and blue juice? I know Airbus does not use Alclad, SAAB didn’t either, so they corrode pretty quick. I have seen some corroded ga planes but they usually lived by the ocean in warm waters. Alaska cold tends to be a good preservative.

    Longeron repair help please

    It’s not the best place to put that spot of grain. Kind of what you get with older homebuilts.
