i came to share and see what people would say. Like i said i appreciate your opinion i just don't necessarily agree with it 100%
Esc is a 120 amp with a 240 amp burst ratting and it sees amp draw in excess of 100 amps in my boats so it can handle a good sized load. 3700 mah 25 c is good for 92.5 amps so with me only pulling 50 amps at WOT they are just fine.
Do you have an eagle tree logger? At full throttle about 1000 mah is used every minute after 2 min 40% of a 5000 mah battery is used up, if your batteries are still giving you 8 volts after 40% ( more in the case of the 3700 mah packs) then you have some amazing cells.
If the motor was more efficient energy wouldn't be lost as heat, or due to resistance which would result in higher rpm under load. So really efficiency and KV actually are directly related
Incorrect for the very reason you stated; that to run close to 750 watts you DO need to pull 100amps from the motor, something your ESC and batteries cannot attain. That's the point.
Why would i want to pull 100 amps from a motor only rated to handle 50? As mentioned earlier the esc is up to the task, i know the batteries aren't. Im having a hard time understanding why pulling 50 amps from a motor rated at 50 amps is not effectively using it. I think we can both agree that on 4s 41440 rpms is too much, while a gear box is a nice idea there simply isn't room for one, nor is there room for a 4s pack big enough to handle a 50 amp load.
If you only saw how hard I was climbing yesterday you'd know i wasn't lugging around extra weight.
I have 2 2s 25c 3700 mah, 1 2s 20 c 3700 mah, a 2s 20c 3200 mah , 3 2s 20c 5000 mah pacs and a 2s 25-50 c 5000 mah battery which is also why I like my setup because i can utilize all of those batteries and have plenty of time at the field.
While you may not destroy your electronics ( only prematurely use up the batteries ) given what you are currently doing, you came here seeking advice which you received as to what problems exist with your reused electronics.
How will pulling 50 amps from a battery rated at 92 amps constant prematurely use up the battery? Its only 54% of its max rating, well within a safe limit.
I received your advice. While i see that you have been a member for a good amount of time and have several post it doesn't mean you are right. After all I was out shopping yesterday and talk was still cheap, unlike the option you suggested which would require spending 40+ bucks on just mounting hardware and then buying an additional plane. The whole point of using these electronics was because they were laying around (free so to speak), I didn't choose them specifically for this project but i saw a possible way to make it work and i executed it. It happened to work out. I could buy a smaller motor and esc for the plane for nearly the same price as the gear drive and motor mount.
So yes you gave advice i just don't consider it any good, but I do appreciate your thoughts on the matter and the time you took to respond to my post.
