KISS ESC 18a & 12a 2-4s

Hi,

im praud to present our new multicopter high preformance/low cost small size ESC the KISS ESC's (Keep It Super Simple)

there are two versions at the same size (12x23mm).

The KISS ESC 12A 2-4S

available at flyduino.net http://flyduino.net/KISS-ESC-2-4S-12A_1

and the KISS ESC 18A 2-4S

available at flyduino.net http://flyduino.net/KISS-ESC-2-4S-18A_1


features: (except of the max continius current and the price, both versions are identical)

- All N-fet
- Active freewheeling (no partload problems) (complementary PWM)
- regenerative/active braking (because of the complementary PWM the ESC brakes the motor activ if the throttle signal goes lower)
- fast gate drivers (high efficiency because of very low switching losses)
- adaptive deadtime (no through shots but also minimum possible body/freewheel diode use -> less losses)
- low RDSon fets -> 3,5mOhm on the 12A and 1,66mOhm typical on the 18A version
- 32kHz output PWM frequency (not audible)
- hardware in and output PWM (zero signal jitter)
- 10-bit PWM resolution (~950 usable steps)
- programmable throttle signal range
- normal PWM input (1000-2000us 25-500Hz) and oneshot125 PWM(125-250us -> for use with up to 1kHz) selectable with a solder jumper
- selectable rotation direction with a solder jumper
- fast throttel response (no ramp used)
- capable of up to 300.000 eRpm (up to 270.000 recommended)
- there is no external capacitor needed. (you may add one if you use long power wires or if you need a smoother voltage)

because of the high possible eRpm it drives motors like the 1806 2300kv, 2206 2000kv or 2206 2350kv on 4S without problems

here some Flight Videos


Warthox with Warpquad (1 min 39 sec)

(warpquad / sunnysky X2204 2300kv / 5x4 probs / 4S)


mwc quad // mini cp (3 min 29 sec)

(minicp / MT2206 1200kv / 8x5 props / 4S)


20140531 190338 (1 min 55 sec)

(pylon air race at kopter in ostheim.. final me vs warthox.. warthox wins )


kiss esc test (2 min 5 sec)

(on a modifyed warthox 25cm frame with 4108 720KV motors, 12x4 propellers and 4S 1600mah lipo)


mwc quad // kiss esc flying with the developer (2 min 42 sec)

(warthox: minicp MN1806 7x2 prob 3S, me MN1806 5x3 prob 4S)


a Compersion done from FinalGlide:
KISS esc Comparison (7 min 7 sec)



a how to solder with moderate tools:
KISS ESC soldering (6 min 12 sec)



here a test of the max continius rating:
KISS ESC load test (14 min 39 sec)

test conditions:
- 16V (4S)
- MT-4008 770KV motor
- 12x4 tiger CF propeller
- part load (~80% throttle on the KISS 18A and ~50-80% on the KISS 12A)
- ESC in moving air, but not in direct airflow of the propeller


regards

Felix

Asome ESC!!
Is it based on the Ultra-ESC, since it also has Active freewheeling?
Will there also be a 6s version(s)?

When do you expect to have units to sell? Price point? I suspect once you get a few out to people to try and get positive feedback, you will be flooded with orders.

hi,

the software is based on the ultra esc FW. but as it uses different HW it is not the same. so its made just for this ESC.

6S is not so easy at this size and price.. but we will see
