    Thanks for the suggestions on batts. Now, I understand the relationship viz, mAh & C rating and the need for a suitably rates ESC. Thanks, man.

    So, based on the above, the motors' Wattage must be matched with the power supply, right? i.e the number of cells in the batt for max efficiency and to avoid damage to the motor. Is this correct or way off?

    One thing I don't understand is, where did you get the 5A in the above equation? Some clarification will be appreciated.

    Cheers

    No problem.

    The 5 Amp is just a constant (example) used to show the difference between 6S and 3S.

    Yes if you mean the ESC as part of the power supply / train. The Motor, ESC and Battery will perform based on the load. The load is the spinning propeller drawing air. The more blades, the larger the diameter, and pitch, will increase the load. i.e. Spinning an oversize or over pitched prop would draw larger currents.

    The number of cells will be dependant on the ESC Cell rating. ESC Specification will advise what cell count is supported by the ESC.

    To be able to get the tune correct between all the components you need the thrust stand.

    Hi B,
    I've been searching for a sandable glue for EPP/Styrene (the Cessna/Lanyu) for the past few days but not been successful. Would you know if any such product exists?

    Converting this tricycle to a tail dragger.

    Cheers

    Hey B, a minor glitch. Sometimes, I don't receive the email notification for the thread. This is necessary for me to especially print out important stuff e.g. Lipo-101 etc.

    Any idea why and/or how it could be fixed?

    Had a look at the suggested Thrust Analyser... Oh boy, even if I bought it, would have a clue how to use it. Might have to bother you to no end. Is there any straightforward method to calculate?

    cheers

    DELUXE MATERIALS BD5 MODEL Filler LITE WHITE 240CC DELUXE 5060243900524 | eBay

    Deluxe Materials BD48 Wonderfill 240ML DM-BD48 DELUXE 5060243901248 | eBay

    Deluxe Materials Micro Balloons DM-BD15 DELUXE | eBay

    You will need to find a source.

    You have to be subscribed to the thread and it only notifies you once. You need to view the thread for it to notify you again.

    Thrust analyser is easy.

    When can discuss when you get one.


    Cheers.
