My current quad uses Turnigy Plush 30A ESC's.
I flashed them with SimonK's firmware last weekend.
I like these ESC's, but read that if you order them now, they'll come with a Silabs CPU, which isn't flashable (yet).
What's the best alternative?

Btw, I know about this table, I'm just probing for your experience.

EDIT: Just so you don't have to go through the whole thread: general consent is that the Hobby King ESC's are perfect.

I just sold 8 Turnigy plush ESC's cos they had SiLab chips and then got the Hobbyking F-30A because they have the programming pads in a row, N-FETs and cheap :)

Thanks DanZ. Looking at their pcb, they seem lower quality than Turnigies (link). But that's probably where the price difference comes from ^_^

ive done 12 rctimer esc's. The 18,20, and 30's are all the same board w different fet counts. The pads are in a row, and they all use the tgy.hex firmware.
Oh no, they will be back ordered after I post this lol.

+1 >> I have done about the same number of RCTimer 30A and 18A.

You can also buy pre-flashed from quadroufo.com. I know a few guys who have done this rather than flashing themselves. http://www.quadroufo...ff5pqm3kipco0e1

You can also buy these http://www.hobbypart...02-25a-esc.html I have flashed a set of these for Astronutski. They use the tgy.hex FW also.

FA30 and FA20 are slightly better due to the external oscillator. I have never tried them yet, but have had no issues with older Plush, HK-SS20A-HW (the newer ones seem to have a locked Amtel Chip), and Rc-timer.

+1

pads in a row, n-fets, + ext oscillator. I personally haven't tested them yet, but many people swear by the F-30A and F-20A's on rcgroups. I just flashed a set of 6 yesterday and will be putting on quad later tonight to replace flashed dynam detrum ones that I flashed -- since I'm having weird throttle drift with those.

Are the FA30's flashable or have bin flashed?

They are flashable yes and have pads along the edge, but do not come flashed with SimonK from HK, you need to do that yourself or buy from someone flashing them.

Yup, I'd recommend the whole F-xxA line...for the price, they're pretty awesome. I'll have pictures of a few more boards up shortly at http://0x.ca/sim/esc/ (just took pics of HiModel FlyHyper and F-80/90A boards). The only possible downside with the F-30A and similar boards are that they are basically unusable for multirotors until flashed, and they have filtering capacitors on the sense lines that makes them a bit more sensitive to timing loss at extreme currents (and possibly a bit more difficult to track the demagnetization as a result). But in most cases, they're great.

Out of curiosity, why would one get the F20A vs. the F30A? Both are nearly the same in terms of size and weight (unless the HK specs are not correct)

F20A:
Size: 54 x 26 11mm
Weight: 30g

F30A:
Size: 54 x 26 11mm
Weight: 32g

Are the FA20s really 30g? That's just 2g less than FA30 and 11g more than 18A plush, so that's why I wonder. (19g vs 30g vs 32g)

Interesting about the filtering capacitors. Can these be removed / bypassed to make a more reliable ESC?

Believe the 20s are just 30s with different fets is how Simon explained it to me as I recall I think.
