    New to Electrics HELP

    Hello my name is Kevin and I have a couple question about electric motors. I have been flying glo for years but am building a plane that calls for a 15 size glo engine and am considering converting it to electric. I purchased a Parkzone brushless p-51 and have been enjoying it but do wish it had a bit more power. I have looked at engines but really don't have a clue as to what to select. I have seen some of the engines markes as a 15 size etc. But many are rated differently. The motor in my P-51 is a brushless 480 outrunner I believe. So I am not sure what to select, and don't know what the kv rating means, I thought someone said kilavolt, but am not sure and don't have the knoledge to know is that small or large etc. I know what glo engine sizes are and what types of planes a certain size engine will do. I would really appreciate any info that anyone has, at this point I am clueless what to select. I do know that I want this plane I am building to be very fast. I wish the P-51 I bought was faster. Thanks for any help.

    There are many motors out there that will be a good fit for your 15 sized plane. The higher the KV rating, the smaller the prop. This is not a perfect way of thinking this through but is sort of close. Low KV rating is like a 4s engine. Swings a larger prop slower. I higher KV rating is a 2s motor spinning a smaller prop faster.

    What plane are you thinking of converting to "E" power?

    For a standard plane here is a 15 sized setup.

    I used a calc program with an APC 12X6 prop.

    WATT meter, yes this is a MUST HAVE! If you do not use one, you will let the magic smoke out.

    With the above setup, it calc's out to 67 pounces or 4.1 pounds of thrust.

    Here is the online calc program

    It may seem like you are learning a new language, because you are Just start plugging numbers in and see what changes. It will take a little time but it should start to become as clear.
