    Actually that is how Cauliflower welds (too hot) always fail. Just next to the actual bead....

    replied to Resonance...?
    Rudder flutter would happen also if the tension in the rudder cables is not maintained. The tension we specify is 40 to 45 pounds. Its easy enough to adjust the tension via the turnbuckles. It should be checked every 50 hours or in pre-flight simply by feel. I also recently saw that people don't tend...

    I see. Do you have any pictures of their stiffening plates Mike and where are they supposed to get installed.

    What about the hub bar or blade failure? Any report on that or did I miss it. I do remember there was an incident in Poland in an ELA and the blade left the gyro in flight and then...

    They say that they can takeoff in 60 feet one up in no wind conditions. So may be it can happen?...

    There is no way that Figure 4 on BEA2015-0318 report are from ELA. Those just look to be even visually horrible welding with a doubler plate on top by someone else, right?
    Usually operations like welding are done the same way on the same areas via sometimes called special definitions process....

    replied to Radio question
    Hi Mark:
    I do not have any radios with dual volume in stock not spoken for that I could send you that have enough hours for me to say they will fix your issue right now. I did a month ago.
    I have not had this issue on any radio. I have had other issues with not having dual volume control...

    replied to Radio question
    Dave I agree. MGL radio and intercom are eventually much better and more expensive than FlightLine. But for whatever reason Mark seems to be having issues with his MGL. The radio we originally installed had one volume in it. That usually works fine if your headsets or helmets have GA impedance. Mark...

    replied to Radio question
    Amazing that Mark is having this issue. Matt did talk t me and did say that a few others in airplanes have had radio frozen as well and its definitely something to do with the radio but when I asked him if he knew if it was firmware (software) or hardware, he said he was not sure yet about that....

    Whoa !!!! Tail came off due to bad welding? You sure?
    We had resonance issue in testing when we had lightened our tail and also changed tubing vendor to a US mill manufactured tubing. For some reason when the tail got side gust load its frequency matched a harmonic of the welded frame tail boom....

    replied to 912 vs 914
    912 ULS is more bullet proof engine than 914 UL in my opinion. But 914UL is vey reliable. You simply need to understand there is extra wiring, lights to monitor for turbo control unit caution or warning, extra connector, electrical fuel pumps, a pressure regulator, manifold pressure to monitor, and...

    replied to RAF Rotor Blades
    So most gyroplane designers of commercial gyroplanes have no clue of effect of density altitude on true air speed? Because rotor RPM is nothing more aerodynamically on a blade section than speed. Really Chuck? May be you should restrict this comment to a subset or particular manufacturer(s)....

    Yes it does. I have friends like Russell Brown here who have 5000 hours on a their fleet of 914s (multiple engines) with just top ends done at each 2000 hours.

    I am not sure about older engines. You could be completely right....

    Hi Eddie
    rotax uses 6 lbs of boost only and allows full boost for only 5 minutes max. The Turbo Control Unit will not allow longer duration and default to lower boost after that.
    The system is very simple. TCU senses Air box pressure runs servo that is attached to waste gate.
    the weakest...

    400 HP on Dick Degraw's Gyrodyne? Jsada, I have not precise calculations for this because I am not building a jump takeoff gyroplane currently but I can already tell you you are way off. Very far off....

    Zephyrhills, FL to Wadesboro, NC delivery

    Delivered this AR-1 with Barry Ford from Zephyrhills, FL to Wadesboro, NC yesterday. Between 84 to 90 knots all the way. 5.5 hours flight time, though we took nice one hour breaks at each stop to relax. Not exactly a direct route to avoid military operation areas a little. Did go through Charlie airspace...

    Hi Jsada:
    Just so you know this isn't the first time I have heard of this idea.
    I am sure you know the obvious problem with this idea and that is it is a system outside the aircraft and you can only takeoff this way from where the system is based. Other practical challenges not being counted...
