nice flying btw.
Where in the heck do you get something like that? Obviously scorpion, but i didnt know they made a 300amps esc

Yes it's still a prototype. Don't know if I will be production material, maybe custom order but that's up to Georges.. It works amazing
so far I am loving it..

Very nice! But why 300amp?

Scorpion 4540 pulls some serious amps. The only other ESC out there that was big enough and readily available at the time was YGE 320. Georges offered to make a prototype and I would test. Weather it goes into production I have no idea.

I understand what your saying and that motor probably can pull 300+ amps BUT for very short periods AND NOT in a heli setup.

If that setup used 4Ah (guessing) in 4.5 mins then thats an average current draw of only 53 amps! Sure bursts of power will be higher but shouldn't be anywhere near 200 amps let alone 300 and im guessing that ESC can handle burst of maybe 350 amps!

I know that keeping the ESC cool is a good thing but whats wrong with using a fan?

Just seems a bit excessive thats all.

Hmm lets see Georges the owner of Scorpion recommended a 300 amp ESC saying that nothing he currently produced could safely handle the power of this motor (that he produced) could put out. I kinda tend to trust the guy who makes a living doing this stuff. He offered to make one to test for free and I agreed end of story...

I can momentarily pull 250 amps with a Trex 550, so of course an 800 sized helicopter can pull in excess of 300 amps. I would think that this ESC must be able to handle momentary amp draws in excess of 600 amps.

Lol.

Justin, those are just spikes not bursts. So lets see 250 amps on a 550 on 6s (spikes remember), 800 heli roughly twice the size would you say? ON 14s YET STILL RUNNING 5Ah PACK, so 250 times 2 (twice the size) = 500, 500/2.333 = 214 amps. Very roughly of course.

Heli guys aren't the only ones who flies scorpion motors! The EDF jet guys can pull some serious amperage!!! lol

trying to state that helis are not the only RC model that can pull major amps. EDF jets on 12s and 120mm+ fans can pull some crazy numbers. as you probly know heli guys arent the only ones who fly scorpion products. lol Idk if im saying this right..

There's a difference between 6s & 14s pulling 250amps in regards to power (watts), but relative to the size of motor & machine for impressiveness, I guess. For 14s that's in excess of 13,000 watts.

And I hope in the near future several E things will lower in weight... like half the weight without sacrificing performance. I imagine this ESC is very heavy.

4540 is rated at 10k watts continuous and over 15k peaks. The peaks were not able to be rated becouse they did not have an ESC at the time that could handle the test. Not saying I am pulling those kinda amps but the motor is capable.

Side note: Man, those 4045 motor specs are just down right scarry... swinging 800mm+ blades. Now I want at least full-body chainmail armor at the flying field, and hurt but not be killed.

I understand but its in a heli not an EDF jet.

Sam2b just hit on something, big heavy ESC to handle the big heavy motor and of course you need lots of battery to handle it AND get the flight time so thats even more weight needed. So we now have a very heavy machine that NEEDS to be run at silly headspeeds to get the pitch response one needs to fly hard 3D. There is a limit unless as Sam2b said they come out with smaller lighter motors and ESC's and smaller lighter battery tech.

It's not ONLY the Scorpion stuff pulling high numbers either. I'm running a KDE 700-495 in a Suzi Laos 800 and at 13 degrees pitch at 1950 my Kontronik Kosmik logs 460 amps at the motor on a simple climb out and then shuts down. I've had plenty of logs showing over 325 amps at the battery and the ESC always shuts down and that's not even 3D flying at all. This is all at 12S using Pulse 65C packs so logically the next step is a YGE 320. In my opinion running 14S would just be delaying the inevitable so I'll probably just skip the trial and error stage and go for 16S.

Let's consider the rate at which the power supply needs to be increased and look back at the 600 class electrics. The trex 600 flys incredible on a high current 6S setup. Then we jumped up 100mm on the blade and went to 12S to get comparable performance out of a 700. OK, let's go up another 100mm and look at an 800. To gain the same performance we might have to jump up another 6 cells or possibly even double the number of cells to stay on track, there aren't enough data points to establish a true pattern. However, we're able to get close to the same performance with fewer cells because of the battery technology and the amount of current the new batteries can safely deliver. 8 years ago we were flying 16C-20C batteries and burning them down. Then companies such as Thunder Power came out with 30C packs and showed us what high C really meant. Now we're flying 65C but burning up ESC's so the trade off is higher voltage. Right now there aren't really many motors that consume that kind of power nor are there many pilots that can handle that kind of power but we're still having this discussion because it's a problem nonetheless. As long as folks keep flying harder and helis keep getting bigger we'll continue to see a need for higher current/higher voltage components.

Cheers

It makes sense. As voltage goes up, amperage goes down. That's if the watts don't change. The problem is guys are addicted to power and can't get enough, and the cycle continues. Call it the Tim Tailer effect.
