    Nice job Dave...!
    You were smart to make this combo your "keeper" since it looks like so much care free fun.

    The narrow needle is a symptom of too much prop , too much compression, too much nitro or any combination.
    This isn't meant to mean that the current prop isn't a good choice, but sometimes you'll...

    That's an interesting write up, but I don't understand their self imposed 22,000 limit. For C/L Combat, 22,000 [with a 5 x 3] was hardly good enough to keep the lines tight on a windy day. I never...

    The "standard" Killer Bee ports are large enough to support ungodly rpm with a 4.2 x 4 prop, so yes that would be hard to improve upon measurably.
    What I'd like to know is if the NIB Killer Bee I...

    To be that exacting, I think you could use a crankcase with an access hole cut in the bottom of it as a holding fixture that you could adapt to the snout of a die grinder.
    Pretty delicate surgery.

    180 degrees duration means that the exhaust cycle begins 90 degrees after TDC and then it re-closes at 90 degrees BTDC. You can actually check timing with a depth mic and a little math.

    I'm surprised to learn that Cox .049s have such low timing.
    This helps explain the question I've always harbored about why they have so much exhaust port area. It seems to be the trade off.
    The low...

    They will also wonder why so many C/L flyers glued so many copper plated likenesses of Abe Lincoln to the outboard wing panels of their planes.

    Too bad you didn't have the Demon finished or you could have salvaged the weekend.
    It was still better than my weekend as an amateur farm hand.

    Most of us can only fly a 24-30 inch span plane 300 feet or so before needing to turn back, so flying at 150 mph just means that you do it more often. If the plane is set up conservatively, it's a...
