    The ribs look good from here. Your boys are getting great experience seeing how a project gets planned and managed.

    The clear plastic wheels are new to me.

    Foremost used to make aluminum disk wheels with rubber O-ring tires.
    At one time I thought MECOA carried some of that stuff.
    Kevin Matney might know about .15 sized racing wheels.

    A good thing is to mount the engine on aluminum mount beams so that they can pull heat away from the lower end of the case. I'll bet it helps the overall temperature, too. The CS / GZ will burn wood...

    Engine #1 was one of Bill Hughes' "runners" and it turned a 4.2 x 4 42,000 but didn't last very long. I kept using the same case with replacement parts but none of the replacements ran nearly as...

    Nice looking gear..!
    The other style of pipe mount uses a pedestal formed out of music wire into a closed loop at the base for screws and washers to grip.
    At the other end of the wire pedestal a...

    It looks like a .010 fuselage in the 2nd photo..!
    Those side exhaust engines look "right at home" but I think the rear exhaust engine should get a dedicated plane that's designed around an enclosed...

    Nice subject for a scratch build..!
    To be practical, I prefer flat bottom wings for most 1/2 A projects.
    I've never seen a saw like that. For cutting metal, I hate using my jig saw only because it...

    Looks like a well balanced layout, nice..!
    Are those surgical scissors..?
    I know a guy who uses cuticle scissors to whip out head shims. I've tried it, but don't have good enough quality snips to...

    The 100 mph mark with a AP .061 is not something I would have imagined. By "locked in RPM", this must mean that the prop is just about a perfect mesh with all the other factors.
    You're at a point...

    The smaller the engine, the less sucking power it's going to have. If the tank is more or less centered for level flight, then you've done about as good as you can do. Keep the fuel line pinched off...

    A lot of the past contest planes are scaled down from larger scale. I scaled a contest plane "sideways" [the same scale as a Guillows Mustang] but used an entirely different building technique. It...

    The degrees of "dwell" the piston has at TDC needs to be measured and split in half when zeroing the pointer on the wheel. I use a flat bar of metal bolted across the top of the cylinder. The bar is...

    I had to take a 2nd look at those numbers after a cup of coffee.
    These engines are so small they aren't easy to check.

    That's a pretty good amount of wood that sheared off. It looks like it was good for any amount of flying you could throw at it..

    If I have a failure like that, I'll dowel it with round toothpicks...

    It sounded real good..!
    The pressure tap works like a charm.
    Keep rough track of how much use you get out of the AP [if you run it exclusively like this].
    It sounds happy to be run with that prop...

    Even with the bad shoulders, I'll bet most doctors would see this being good in general. It's not the line tension of a .049 to .15, but forcing the arm to go through the range of motion. Some flyers...
