    Hi all,

    As the title says, I'm starting a new project and I'm sure I'll be asking plenty of questions. This will be a scratch build except for the bits I can't make and I'll certainly be open to any advice.

    My first major question is if anyone knows the actual G limits of this design? In Budd's pirep of the S-1-11B he pulled +8 -5.1, but I can't seem to find any published numbers. As I do plan on flying this plane hard I'd like to know what it can really do.

    Currently, the modifications I'm planning on are plywood leading edges, wolf tail and probably the wolf cowling. I'm also leaning towards using a different canopy that is more airodynamic and less expensive than the one Aviat sells. Does anyone have a recomendation? As I understand it, the Haigh tailwheel is no longer avaliable. Therefore, can anyone recomend of an equivilent model?

    And of course, is there anything I don't know to ask that I should?

    I have talked to Jon Melby and pulls up to +10. Not sure about negative. As you, I haven't seen published numbers anywhere.

    If you are going to do the Wolf tail and cowling, get the canopy and gear too. I only have the gear and tail on mine. For the tailwheel, I believe I have the locking Raven.

    Look over the plans then look over them some more. Found some errors on them. We have a list of the ones we have found somewhere. I'll find it and list it or garyg will.

    Thanks guys, I'll certainly be posting pictures, but for now it seems I took a day to get my work area set up and learn several ways not to cut a nose block.

    Yep, that sounds about right! I threw away at least 5 mock up patterns and at least 2 actual pieces making my new head rest. It had to fit the existing turtle deck and canopy opening with a sliding canopy that seemed to move in strange ways while being opened or closed.

    good afternoon, I just built an 11b, aviat parts, raven wings with full span ailerons, skydynamic engine and whirlwind 400ac prop. I flew a few hours in it, 19tt, great plane, very honest, very fast and a roll of envy in the extras IMG_20180524_163625231.jpg

    D9A8F81F-D76C-4E6C-817C-DDD403462817.jpeg I’d strongly recommend Tony at Specialty Aero. Great guy to work with. I’m doing all of the mods he offers (wing, cowling, canopy, engine mount, gear, tail, just to name a few). Engine by SkyDynamics, fuselage VR3. 36CEFC5C-2116-4691-8CA0-F2C276AE8C3D.jpeg Tony provides excellent support and hasn’t complained about my stupid questions.....yet.

    Ignacy,
    If you have a link to a video of your plane showing roll rate, I love to see it. That was the one thing I was disappointed in mine. Wish it rolled faster.

    Joshua, I reclined my turtledeck also about 3 inches back at the top. Before I did that my head would always hit it when tilting my head back at the top of a loop, or trying to look over my shoulder. My turtledeck is aluminum.
