    I flew an RX550 and I remember how tail heavy (full power) and how nose heavy (idle power) she was. This is a great fix matt. Thanks for the video. It brings back memories. These were such fun flying machines!

    Great video, flew one a bit in the 80’s on skis. Loved it. I fly the Fireboss tanker now…. same idea… stick and throttle! One question to the RX550 people …. I recently flew a Quad City Challenger and will probably never fly in one again due to the ridiculous amount of adverse yaw. A turn requires leading with the rudder pedal and then opposite stick to keep the aircraft flying properly around the turn…. is the Beaver the same???

    • @mmatt
      @mmatt  5 місяців тому

      The Beaver is not the same. It has differential ailerons to counter the adverse yaw. I can easily turn with either ailerons alone or rudder alone. Using both makes the nicest turned though. I have flown a Challenger as well and know exactly what you're taking about. Lol

    Hi Matt, I was thinking that since weather is going to be an issue here real soon that maybe you could do some hanger videos when you can't fly. I was thinking you could show exactly how a weight & balance is performed with scales and calculations, maybe what you do for your preflights, prop pitching, general maintenance, ect. I know you've talked about some of these things, but seeing it actually done would be better. Just some Idea's for content when you can't fly.

    Greetings from Weyman Airpark! My "V" is on strike as well. I haven't landed at Woodstock in years but I often fly by in the RV4. There's quite a difference in the acceptable Empty Weight CG (for the builder) and the flight envelope (for the pilot). Adding 12 lbs to the tail of your ultralight is quite a significant engineering decision. Can the tail handle it? Does the Beaver have a trim control? Any performance changes are probably due to trimmed airspeed changes (set Angle of Attack). You also probably notice these with fuel load and passenger load, although both are pretty close to your CG.

    • @mmatt
      @mmatt  2 роки тому

      Come stop in sometime! :-)
      Yes, it has a very large acceptable CG range which is nice to have on such a small plane. The only trim control it has are ground adjustable tabs on the tail and I have a spring trim set-up in the cockpit. I had to add significant backforce with the spring before adding the weight and now it's all but slack. With the tail not adding so much aerodynamic downforce, the AoA should be little less on the wing which I think accounts for the increased performance. Ideally I would have removed weight from the front but that's almost impossible to do short of replacing the nose pod with a lighter one. There's just nothing else up front that can be removed. I guess the other option would be to move the engine back a few inches or the main wing forward a few inches but that would an even bigger engineering project.

    Can you perhaps do a video comparing the different planes at your hangar refueling wise. I've seen some which are really easy and others where you think how the h do I refuel it? I think it's applicable to C of G too as some have fuselage tanks and others wings. Sometimes I think refueling was an after thought by the designers.

    • @mmatt
      @mmatt  2 роки тому +2

      I considered that but since their weight varies with the amount of fuel they have in them, the CG would be shifting during flight. Right now they sit right in the middle of the CG range so it stays the same as I fly.

  • @darrylb2052
    @darrylb2052 11 місяців тому

    My concern would be how it reacts in a stall. Aft c of g can be dangerous if the tail has a tendency to drop , potentially causing a whip stall and very poor outcomes. I suppose you will be doing more testing before making it a permanent change. In my 550 if i pull power off and let go of the stick it starts to drop the nose and slowly pick up speed , level out and then repeat. I assume this is desirable
    .Always enjoy the videos Matt

    • @mmatt
      @mmatt  11 місяців тому

      I carried out the appropriate calculations and hove only brought the CG towards the middle of its range instead of being forward. My nose pod has been repaired more than once and is much heavier than it originally was leading to the forward CG. A factory Beaver should have its CG in a much better location without the lead in the tail.

    • @mmatt
      @mmatt  4 місяці тому

      Oh calm down, I did all the math. Didn't use paper though if that's alright, I custom built an Excel spreadsheet. Once I was sure that the math was correct, I verified it by comparing the performance of a practically identical airplane. I've been flying the plane like this for 2 years now and it flies better than ever so I'm pretty sure I got it right.
      (Also, if you skip to 1:57 you'll hear me tell you that I did the math and I even display the results as text on the screen.)
