I have a CC ICE2 HV 120 in my Whiplash 90E. I have logged the temperatures for my first flights on this. 2100 rpm hard 3D resulted in about 170F (75C) on most, and with a few short peaks(1 second, same as sampling time) with a maximum of 233F (112C). Mild 3D on 2000 rpm resultet in 140F (60C) with no peakes.
This was with approximate 32F (0C) ambient temp. I wonder what happen when the summer comes.

What temperature do you guys fly with? Specially you who live in the warmer parts of the world. I guess you might struggle a bit with high temperatures?

That's way too hot. About 70°F max. above ambient temp is what you should shoot for. You can adjust the ESC frequency to get the motor and ESC operating at about the same temp. Higher frequency makes the motor cooler but the ESC hotter and vice versa.

@ arhennie

I think this is a video of yours:

Watch at YouTube

From what I saw in the video, you were running a power hungry Scorpion 4525-520LE in your Whiplash. I would say that this motor needs an ICE2 HV 160A, especially when considering that the Whiplash is a bit heavier than the typical 700 heli. Also, and I don't know where you have yours mounted, but mounting the ESC between frames where the manual suggests doesn't help either.

Bobby was using an 160A in his Whiplash with the same motor:

@barzaun
Yes, correct. This is my heli. And the values referred to with 2100 rpm. are from this particular flight. Right now the ESC is in the recommended place between the frames, and I have planned to move it to the battery tray (where I have seen Bobby has his) and see if there is a difference. But yes, probably I need to go for a 160A with this powerful motor if I must down to the values mentioned by rexxigpilot. Thanks, I will keep that value in mind.

By the way.
Du you know what the ripple voltage actually is, what is the limits here and what can be done if too high?
