This ESC has so many features, you can set every single parameter on the Hobbywing programming software and the optional usb adapter. Fan works great, at the moment Ive only run it on 2S, I have a 6650 Turnigy motor and its just stupid fast.Got this esc and went to turn it on after about 4-5 batterys packs and wouldn’t turn on ...This ESCis basically a clone of the hobbywing xerun 120 which is nice because, well obviously its a lot cheaper, but you can also use the hobbywing programmer and firmware updates. It has very smooth power delivery even when running uncensored and generally has a nice feature set, its nice and easy to calibrate too. I'd recommend flashing it with the hobbywing stock firmware as it has more features than the modified firmware its shipped with (I guess they disabled some of the boost and turbo features in modified to make it harder for you to abuse the thing). The dynamic timing of the stock firmware is a brilliant feature as it allows you to run 0 degree timing upto a certain revs then feed in timing advance progressively as the revs go higher which allows you to squeese ridiculous power and efficiency from your motor. Obviously this feature was intended for stock motors but used judiciously its brilliant for modified motors.
Not had any reliability issues with mine so far, has not skipped a beat in two seasons of racing. Overall a great value ESC.Look, if you want the best brushless controller, you get a Roboteq for 500 bucks.
I can't quite afford that, so I got this instead, running it with a sensored Trackstar 4272 1900KV motor on a HobbyKing Berserker 1/8 chassis. I want the best possible control at low speeds, so I'm running it all geared down and with sensor, and it works pretty well!
Using a Raspberry Pi and Teensy 3.2 to control it, and training a neural network to stay on the track, so my use case may not be 100% mainstream, but it's a lot of fun!
However -- the fan needs to go. I'm running 3S, and the fan wails like a banshee. Given that there's a BEC in the ESC, why not just hook the fan to the BEC so it gets a more appropriate voltage for its design?Brilliant esc for the money, I bought this as my konghead was running absima sensorless and kept cogging, even on 3s, I'm now running this esc with an LRP 21.5t X12 motor and it's a different machine completely, super silky smooth drive and the low speed control is excellent, I can recommend updating to the latest hobbywing firmware to add boost and turbo features, so for me, the USB adaptor is a must, and should probably be included with it to be honest. I haven't tried running this esc on a sensorless so can't comment on that, but I was amazed at the performance for the price, the only drawback is the case does feel a little brittle but make sure it's Velcro'd down well and you should be golden. Make sure you can solder too, there's no connectors for the battery or the motor but HK make this clear when purchasing. Time will tell how good a bargain this esc isThrew this into an FS Racing Marauder for bashing. On 3s with a trackstar 4-pole it's insane. Barely any increase in temps on the esc after blistering speed runs. Only problem with mine was the BEC - it didn't like 3s. Added an external BEC and all is good. 4 stars because of BEC issue.This esc is great and easy to progam with the usb link. I paired it with a trackstar 8.5t only pulling around 35amp. ESC died after 2 battery packs on 2s.This ESC not only works great and reliable in my vehicle but costs half the price of all the name brand items.This is a great esc. I already beat on and works great with that purple 5400kv. No heat issues.Powerful and feature rich ESC at a very low price. I got a couple of these in 60A and 80A already and so far they never let me down.
