New to Electrics HELP
<div>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.</div><div></div>Kevin

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. Motor http://www.hobbypartz.com/96m602-big...826-950kv.html I used a calc program with an APC 12X6 prop. ESC http://www.hobbypartz.com/07e05-proton-40a.html Battery http://www.hobbypartz.com/98p-25c-2200-3s1p.html WATT meter, yes this is a MUST HAVE! If you do not use one, you will let the magic smoke out. http://www.hobbypartz.com/aeo-p0-watt-meter.html With the above setup, it calc's out to 67 pounces or 4.1 pounds of thrust. Here is the [link=http://www.s4a.ch/eflight/motorcalc_e.htm]online calc program[/link] 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. Buzz. |
