It depends, you see if you're not going to be going full throttle all the time then I wouldn't worry.
The motors I have on my 680 hex would also overheat if I were using it like a racing hex
I wouldn't worry too much about ecalc, it's only a guideline. Have you considered sticking to 4s and 13 inch props?

Perhaps check out this video: https://www.youtube.com/watch?v=NdZyeSN8Fzo

So I know a bunch of you guys said not to trust the ecalc charts but i just wanted to get a rough estimate with my motors. I plugged in a bunch of motors and different props and pitches and came up with this.
SunnySky v3508 380KV -14.6 Flight Time
SunnySky x4108s 380KV -14.0 Flight Time
Tarot 4114 320KV -13.7 Flight Time
Tiger Motor MN3508 380KV -13.4 Flight Time
Cobra Cm-3520 350KV -10.9 Flight Time
DJI E600 -8.5 Flight Time
KDEDirect KDE4014XF 380KV-8.2 Flight Time
You guys still say go with the Cobra Motors. If so im going to be buying them in the next couple of days.

Yeah i saw the video and i like the motors alot, the only negative is that there is absolutely no information about them anywhere and no-one is using them on a build?
The thing is, you can't really go wrong if your're choosing the correct KV (and power rating) for your setup. My relatively cheap multistars have served me very well and are absolute workhorses so all that is left is reliabilty and with the Cobras you can't really go wrong.
In the thread there is a strong preference for Cobra motors. However the motors listed above are different sizes / KV. Likely best to pick the size / KV and then pick the brand to some extent...
One other choice on the Cobra line you might want to run numbers on is:
Cobra CM-4008/36 Multirotor Motor, Kv=400
Yeah i looked at those and liked the specs on them. They are not listed on the ecalc menu but i plugged them in the custom and got about a 7 min flight time. I know the numbers are not as accurate as real life simulations but gives me an idea. The 4008 are right on par with my thrust @ 50% i need so im doing some more reading buy leaning toward the 4008 right now.
I get it donw to a couple of motors and then i get a new motor thrown into my head. But i really think its down to 3 and i dont see me changing if from those:
Cobra CM-4008 400KV
Cobra CM-3520 480KV
SunnySky V3508 380KV
T-Motor MN3508 380KV

Im about 95% sure im going to try out the cobra motors and see how they do. Im looking at the Cobra CM-4008 400KV and the
Cobra CM-3520 480KV. The 3520 run $62.99 and the 4008 run $59.99. I know its only a couple of dollars but why would the higher up model be less expensive as a lower model. Which of the two motors should i go with.
