  • that's interesting that you are using skateboard wheels,I looked at them but decided they might be a little weak for my RAF.

    In my opinion the stock automotive Subaru computer has just to many sensors to cause trouble. I use an aftermarker ECU and it has
    all of the essentials to run the engine,a miminal amount of things to fail. and its tuneable from your laptop computer.

    Your not after thrust measurement your after max rpm,it sounds like that the prop is right on if your getting a max rpm of 5,200.

    If performance is not good your are going to need a 2.5 and a 4 bladed prop to handle the extra hp.It never seems to end (spending money). good luck!

    you should take the advice of OBXBarnstormer and Vance both of them have the right answers, change pitch on the prop not gear ratio,do not overrev the engine.

    One of the reasons I have a reliable engine is that I have limited the max rpm,and I use prop pitch to control the RPM,by making...

    according to the diagram for the rotax 914 if pump 2 is the only pump running the fuel is going is a loop through pump 1 and there would be very little pressure on the system to

    the regulator and carbs. so there has to be a one way valve in the pump on the R side of the diagram....

    I expect my takeoff distance to be about the same,I prerotate to 150 rpm and then start my roll,what has made a difference is the position of my mains having,
    moved my wheels aft enables me to get a better rotor angle which increases my rotor speed in a shorter distance,this causes my increased...

    replied to Subaru 2.2 has limited rpm
    Sounds like the pitch setting on the prop,I have my 230 hp Subaru set @ 5,200 wide open with a 5 bladed prop on my RAF, it climbs good at that setting and It runs great.

    I have talked to other RAF drivers and they prefer the 5,200 RPM setting instead of the higher 6,000 the overall performance...

    Your still flying Paul 6 years ago I talked to you about moving my landing gear back and you supplied me with a drawing of how to do that,

    over the years that modification to my RAF has saved my bacon a lot of times. Thank you, really glad your still here.

  • All flying machines have there differences,all that's required is the pilot be trained to actually handle that particular machine properly.I had to really learn the
