purchased this ESC for use with a 10S setup drawing 105 amps. On fourth use the ESC stopped, made a loud pop and burst into flames causing significant damage to my jet. The ESC was being used well within its stated voltage and current limits. I have filed a request for return of the ESC to hobby king but even if it is approved it has caused several hundred dollars of damage to my jet. I would strongly recommend a different ESC
if you are edf flyer and if you burned a lot of money for esc like me, this will be the solution. got experiences in many esc - YEP HV, hobbywing HV, ZTW HV and this gonna be the best. currently using this for stinger 90 8S setup and keep extra one for spare as it's always out of stock.
Great ESC, I have 2, both in 12S set-ups with Scorpion motors, drawing 60-85A. As with all electric installations YOU MUST MEASURE THE CURRENT the prop I was initially recommended drew way too many amps. As a rebadged Hobbywing ESC, will work with Hobbywing program box.
I have 9 of these for mainly 3D planes. All running 12S. The throttle response is very fast - perfect for 3D planes.
Got this for my HK-600 GT and it looks like it was a good decision. The spool-up is slow enough, and the governor seems to be stable. I`m using this ESC with my proven 8S 5000 mAh setup with 2x 4S. The anti-spark circuit works well. This ESC is like shooting on sparrows with huge cannons, my setup draws a maximum of 45 amps, but i don`t wanted a YEP ESC this time. Overall, i`m satisfied with this ESC.
Connected the K_Force 120A HV it to a Rotomax 1.20 outrunner, pulling ca. 80A on 9S with an 19x10 apc prop. Pwm 8kHz and advance 19 degrees. On the third flight the esc went up in flames.
Excellent quality, just added my fourth one, this time for my Kyosho Corsair 120. Make sure you get the program box for it, makes programming very easy. Made by Hobbywing.
Wonderful esc for the price! I use it in my edf with 8 cells, it pulls 110A and after each flight is barely warm. At first i was a little disappointed because when i connect the battery it doesn't emit 8 beeps (as per number of cells) but after, reading the manual, i discovered that those esc make a long beep that indicates 5s and normal beeps for any more cell, so in my case it emit one long beep and three short ones
thank you Hobbyking!
I can highly recommend this controller. I started 45 times this summer with this control and landed safely. I need the controller for the Rotomax engines, 1:40, 50cc, and next year, 2014, for SK3 F3A Competition Series 28 pole outrunner. With the programming card, Turnigy Multifunction LCD Program Box for Brushless ESC, it is very easy to set the controller to the motor. Thanks HK, so it makes it fun. Best regards.
Rotomax 1.40, Popeller 18 x 12. The TURNIGY K-Force 120A-HV OPTO, and 2 x 5S Zippy 4000 Compact 25C, measured 65 Amps and 2300 watts. The Rotomax makes a good impression.
