    DiY rotorblade

    You can build Bensen timber blades. We built six sets a number of years ago, and all flew fine, mostly with no adjustment to the trim tabs. The difficult part is the scarfed joint on the plywood skins. This must be done well to be safe. We used the blades on our gyrogliders, and when...

    Flapping warning device

    The landing problems seem to be concentrated on hardlinked machines. The takeoff problems seem to be concentrated on flat-disk prerotation machines. Seem like design issues to me. I am curious to know if an instructor taught you the fast landing technique.

    Actually, I have both, and on turnaround at the end of the runway after bactracking, I use both simultaneously. 40 seconds into this;

    Having different opinions is not close mindedness if you have reasons for those opinions. That applies to either side of the debate. If I was flying a MTO, I would do what you do. That said, a lot of folks are breaking up machines for no good reason. It is not going to change unless something...

    It needed a softer spring link. Mine is quite soft, but I've seen some that are nearly rigid.

    You are not wrong, but.... One of the gyro's top selling points is the ability to touch down at slow speed and stop quickly. Why sacrifice that for the benefit?? of hard linked nosewheel-rudder.

    Could be that it is still ticking..... :) But seriously, the fact that an individual has not succumbed to a booby trap does not mean the booby trap isn't there. The MAX was doing fine for months....... until it wasn't.

    Regarding the 'duckwalk' issue, I had a video of one such, not a Dominator, but similar geometry. Took about 20 viewings to figure it out, but it was a blipping of the throttle in the flare that kicked it off, by causing a momentary yaw at touchdown. It settled down, but it was ugly, and I...

    The hard-linked nosewheel-to-rudder is the other half of the Eurotub problem. Easily fixable, but not fixed. Why not? After all, a technical fix would be a proper fix, as opposed to telling the pilot to keep the nose up, which clearly doesn't work. I think it would be fair to say that all...

    Overhead Stick - Drag vs. Control at Higher Speeds?

    No noticeable aero drag forces on mine either. Interesting comment from Jake re the offset kink in the stick. I was delighted to get rid of that, and find no problem with the visuals with a straight stick. Its a bit like looking out a window. You don't really notice the window frame bars, if...

    If I understand it correctly it reads rotor speed and ROTOR acceleration, not machine acceleration. How do they calculate nominal, or do they let you set it yourself.? How much acceleration is enough? You could have an accelerating rotor and still overrun it by accelerating the machine too...

    Might be easier to just learn how the damn thing works! How about proximity sensors on the teeter stops? My guess is that recognition time+reaction time>> correction time available, whatever system you use. See line 1.

    Two comments; 1) For a given gyro/rotor setup, we know the combinations of airspeed and rotor speed AND DISK ANGLE, that cause flapping on takeoff, so by monitoring Rrpm, and airspeed AND DISK ANGLE, this ............etc. You will need to measure all three. There are two other methods...
