I recently built a Vulcan UAV Black Widow with KDE 4014's and 15" props. At the time I was using Spider Simon K 40A ESCs. I was having trouble lifting a 5D3 and gimbal comfortably (around 80-85% throttle) and so after some modifications to the motor mounts I switched to some 17" props thinking that this wouldn't be an issue. On my first test flight I had a ESC overheat and go into self protect mode. I guess with the Spider's that means they just turn off! So that ended badly. Tried another ESC of the same brand thinking it was maybe an issue with that one and had the same issue. Put a few on the bench and they could only handle 100% throttle or 16-17A for just a little over two minutes before they'd shut down. I was told that they might have a timing issue with high pole motors and that this could be causing a overheating problem. So I bought 8 KDE 35+ A ESCs based on the spec sheets for both the motors and the ESCs. I decided to bench test these and they get about 5 minutes at 16-17A before going into a protect mode.
So I was wondering does 35+ A continuous actually mean that or is that only for a certain period of time? Is it safe to run these ESCs and the 4014 props with 17" T motor props? I'd hate to replace them all and only have the same problem happen again. Could there be something I'm missing that's causing this issue with overheating ESCs?
Thanks to whomever is kind enough to take the time to respond! I'm truly stumped and a little concerned about moving forward with this project now.
