Excellent, very well done and informative. I cut out the 3m tape, and did not cover that thing sticking out on the bottom. Also cut out the ESC tray so that thing had a square open underneath it, for circulation! Thank you Cruz. It looks like there was quite a few "updates " on the new ESC! Interesting to say the least. Anyway, so far my new v4, if we call it that, has been fine since I installed it two weeks ago.
Double layer motherboard is beneficial for heat dissipation, separating the driver board and control board. MOS does not shrink. Due to V3esc, we do not have enough damaged samples to inspect the issue. So we replaced the new mos supplier and insulated the motherboard as well. Performed well in the 48 hour durability test at the factory
