    Hot! HB PDP .21

    What a cool little engine. I've posted the figures for my ST G20 .23 for comparison. I thought this one was strong.

    HB PDP .21
    Temp: 51°
    Powermaster GMA 5/22
    Fox Short R/C plug
    APC 9x4:
    13,562
    3.13 lbs. static thrust
    .42hp

    And...

    Super Tigre G20 .23
    APC 9x4:
    12,768
    2.55 lbs. static thrust
    0.35hp

    I guess PDP is for real.

    RE: Hot! HB PDP .21

    I'm using Pe's spreadsheet:

    If you don't have Excel, you can use OpenOffice like I do:

    http://www.openoffice.org/

    It's 100% free open source software and does everything Microsoft Office does.

    Thanks Dave, I have Pe's software also. I was just wondering if you had something else I could play with.
