    Well, so much for concerns being rested.

    When I get home tonight I’ll get another encoder wheel setup, with as close a diameter setup to the stock BCG wheels as possible.

    I should’ve done that in the first place anyway, even with any errors, this will give as close to ‘real world’ results as possible.

    uA…

    Thanks for laying my concerns to rest, now I don’t have to worry about it.

    Something to keep in mind…The BCG PCBs have mA limitations. Initially I tested this by using my Multimeter, in a closed circuit with no load I got a reading of less ~275mA (A 350Z booster PCB read ~320mA, boosted).

    While the lower RPM motors seem pretty right on, i’m worried that whatever calculation I’m not accounting for (while no noticable factor at lower RPMs) is showing itself at the higher RPMs…Explaining why I got readings 2,000RPMs lower than rated on the 3.8 motors.

    Micro, great work!

    Spanky brought up a good point, which now makes me believe I need to look at my resutlts (I did Power/RPM tests at: http://tinyrc.com/forums/showthread.php?s=&threadid=10662).

    The encoder wheel used to test the RPMs (in my tests) is CONSIDERABLY larger than the standard wheel diameter.

    Does anyone know what the calculations are to compensate for such things?

    Thanks.
