The RCTimer one comes with bootloader installed which makes it easy to upgrade firmware using usb linker or arduino.

Both BlHeli and Simonk support braking and oneShot making it a good kiss competition.

Maybe should get added to the OP.

CoolD - you cooked the cap off of one of your SN20's? Was that running SK or BH?

blheli 13.1 with damped light, it didn't cook, just came off I am assuming its bad soldering on the manufacturer's end.

Reposting from original post on the bearhug thread:

Did a second test on the rctimer sn20a escs. Man I'm loving these, 3 flights in a row pushing them harder than I ever did the bearhugs and couldnt burn a single one (I was literally trying to). Heres a video with the mobius this time. forgot to angle it up sorry!

Dont forget to include UAVOBJECT's link as retailer for these esc mini.

Is there another retailer with these in stock besides UAVObjects that anyone knows of?

no, but you can always order from rctimer and select dhl shipping for $15 in case you don't want to wait.

we could check with uavobjects to find out when he will replenish the stock

Is it true these use the same fets as the kiss esc's? If so are we talking maybe just as fast as kiss esc'?

I don't think so, as per the blheli docs the high side FET's are slow to turn on for SN20a, the kiss description says ultra fast FET driver.
unless somebody can check the part numbers we are only guessing here

Maybe I read wrong but I read somewhere both fets are AON7520 in kiss and sn20 sn16. Lol I copy and pasted the fet number to do some research. I am still looking now.

Either way I am going to pick up a couple 16amp to see how the perform. I guessing the sn20 in blheli works on the 16's? They seem pretty close to each other, the 20's and 16's?

that's what the blheli doc says, same firmware

Can anyone compare it with kiss in terms of performance?
