Ok so I have a Jive 80+HV with a heatsink. According to Kontronik's website:
It is possible to raise the performance enormously by installing an additional air or water cooler system. The naming 80+ means: minimum 80 A. Extra cooling may double the performance of JIVE ESCs.
I acquired a Scorpion 4525-520 ultimate motor - am I just looking for trouble thinking this ESC will be ok for it? My flying style is pretty tame - flips, rolls and some tic-tocks.

Thanks,
Angelo

That's pushing it with that motor. Loops and rolls are fine with appropriately modest gearing. Tic tocs can cause pretty good current spikes that might induce a shut down. This is different than what I would say if you had a Pyro700 or a 4035 series Scorpion, in which I would say you would be more or less OK. The motor you have will draw a ton of current if you push it, so you must tread lightly.

If you used a higher gear ratio (smaller pinion) and kept the HS around 1900 it would work fine but then if you did that it makes that motor a bit of a waste of money. I'm guessing you didn't buy that motor to be conservative!

60% of the time, it works every time!

The Scorpion 4525-520 will easily overamp the Jive 120HV with modest gearing, a modest headspeed, and a gigantic heat sink with plenty of cooling air. So I would have to say that you are really asking for trouble if you attempt to use that motor with an even smaller ESC. I am using a Kontronik Kosmik 200A ESC with that particular motor because the Scorpion 4525-520 will draw upwards of 400 amps at times. Even if you are flying very conservatively, I would say with that particular combination you are describing, in short order you will have a fried or damaged ESC.

Edit: By chance are you putting the Scorpion 4525 in a helicopter which runs only 500 or 550mm blades? You don't describe the helicopter you are using it in. If you're flying a Trex 550 or a Logo 500, you will probably be OK. I just initially assumed you were flying a 700 sized helicopter.

It was going to be put into a Rave ENV 700 - I have since put in a Scorpion HK4035-560 and sold off the 4525-520. Not ready to drop big bucks on an ESC that'll handle that motor - at least for now.
