AfroESC 30A + HL W42-20 880KV = Stuttering/Sync Bad
I have a Quadcopter that's somewhat custom, using hex600 sized arms, but a quad chassis that I built. I had been running this on a single 3s 5000mah pack, but wanted to move to a dual 4s 4000mah setup since I have a lot more 4s packs available.
The ESC's on there were the red brick 30a ESC's from ebay, cheap. They claimed to support 3s-4s, but running a single 4s pack for a short time caused the magic smoke to come out of them. So, I bought 4 AfroESC 30A esc's with the latest SimonK firmware on them, the SAME ESC I run on my Hex800 with a bigger motor with no problems on dual 4s packs.
The motor I use is:
HL W42-20 880KV
The ESC is:
Afro ESC 30Amp Multi-rotor Motor Speed Controller (SimonK Firmware)
It seems to run unloaded with no stuttering/sync problems, but I've tried 10x4.5, 10x5.5 and the prop I want to run is a 12x5.5. The problems don't really seem to change all that much dependent on the prop size.
I've tried EVERY single thing in the firmware that I can change, and still have stuttering problems.
The best I can get it, is that if I set it with timing for about 15, change the power rates to bring the power in VERY slowly and set the SLOW_THROTTLE to 1, I can get it to run all the way up to full throttle, as long as I don't have any sudden throttle changes.
I swear I've flashed it probably about 100 times now and changed so many parameters in the firmware, but nothing very reliable. Some changes prove less stuttering/sync, but some changes I can't even get it to spin up at all without the problems.
Currently I found the best version of the SimonK software that provides the least amount of stuttering is:
Can anyone please give me some advice?

afro esc sync loss
I crashed my tarot 650 twice with afro esc's loosing sync. Pretty much tried everything as well. Seems like certain motors just does not like the simonk afros. I changed my 390kv multistar motors with rctimer5010 360kv and problem solved! So I suppose you just have to get the combo correct
