    AMA 426

    Broke in and test flew my two 426 airplanes this weekend, and this motor is just sweet.

    Nice job Mr. Jett these run great.

    Those engines sure appear to needle nice.. When I was holding Dave's plane the tach seemed to follow the needle very smoothly.

    RE: AMA 426

    Great to hear, I just bought two of them. Any chance you could post how you set up the remote and fuel shut off up? Also are you allowed to use a regular NVA instead of the remote?

    Thanks

    RE: AMA 426

    Personally, I like the remote needles. There is virtually no delay in needle settings and I just like the safety of being a little bit further behind the prop. Here is how I install mine. I hear there is one that is mounted through the rear muffler bolt now, but I haven't seen it.

    I went with Barrrel carbs for another $30 versus the venturi / pinch off just for ease of use trading between this class and our local O.S. class.

    RE: AMA 426

    If I was building the fuse myself, I would have glued the 1/8" ply to the inside of the nose instead of the outside. Just remember to fuel proof it, thin CA works fine or thinned epoxy, dope, etc..
