lake_flyer said:The 'old' version 1 ESC/motor combination is extremely reliable, do a search on the net, youtube, how many videos are there with motors or ESC's burning up? I'm sure everybody posts a video on youtube when that happens. Millions of these motors/ESC's have been sold and used (and not only in Phantoms).
At least until DJI came out with the 2312, suddenly there's a lot of talk about unreliability.
PhantomFanatic said:Maybe it is because they upgraded to more powerful motors and ESC, but failed to upgrade the wiring to them, by using a lower AWG = bigger wire. At least one person posted pictures of wire damage leading to all ESCs and motors. I agree with him,that the wire size is too small for the increased amperage.

Appears to be far more likely that the problem is that the IC driver firmware on the older ESCs is inadequate to manage the higher current draw of the 2312 motors. DJI tried to fix it with ESC firmware version 2.0, then when that didn't work as well as they wanted, they upgraded the firmware again to version 2.1, the current version. Unfortunately, even though they knew it wasn't working well, they left all those no-version and 2.0 version ESC's on dealer shelves. Now we're apparently getting crashes from fried ESC's causing their motors to stop in mid-air.
Unlikely that the much-ballyhooed "thin wires" is contributing to that problem. I suspect the wiring damage that showed up here occurred after the FETs on the ESC fried, not before.
Hughie said:The reason the wires are getting hot at the ESC end is (imv) simply down to the fact that the MOSFETs are getting very hot (they are meant to run hot by the way), but it probably does not help that many of the motor wires soldered to the ESCs are done so with the wiring directly above (or touching) the MOSFETs.
I would go for the v3. Do tell the seller though you will not settle to get an old stock v3 delivered. Let the seller garantee that your v3 bird has ecs's with v2.1 fw inside as well as a vented eigi unit . If your seller is not willing to give you a writen garantee in that respect, don't weast/risk your money there.mdj89 said:So should I go with the 2.0 version instead of the 3.0?
Narrator said:There have been suggestions that low rpm could overheat the ESC due to less cooling. Abrupt breaking of forward flight by reversing has also been attributed to ESC failure.
