Can I use it with my homemade Car Alternator used as Brushless Motor, which will run a small E bike with gearing reduction to the wheel through chain drive. Thanks.

Hi, does anyone know what Firmware is best loaded onto this ESC? information is a bit vague out there. There are 2 bits of software for the USB program adapter (AU and Global sites are different). Global has the hobbywing software with the available firmware versions being the below. Currently its being used in a firestorm with a 4 pole 4000KV castle motor (their ESC fried after 5 runs) V3.0_110930_Mod V1.10_090205_Mod V3_508_No timing V1_508_zero_rev V3.0_131205Stock V3.0_110930Stock V1.10_090323a_m thanks in advance

Simon: I use 508 No timing in spec and the HW LCD programer. I have the full Mod load in my DB01RR and an 8,5. OMG it's fast. I had one of these esc's in my Dingo SCx4 with a 4000/4 pole but the bullet connectors kept unsoldering. A DESC410V3 only takes saddle packs

Thanks Btrukr. will give it a go. hobbyking said that warranty is void if changing the firmware but have seen in other forums people tinkering with no problems. will try ater today. Which LCD programmer do you use?

I run them the first time in Mod how them come from the factory, then change to what I want. It installs with a computer just like any HW esc. I use the usb adaptor and the LCD box for track adj

Seems that for now there is no way to program by app or phone.

This uses the same chip as a hobbywing so Your need the program with the usb link sold here.

Fridrik: I use the LCD HW box for at the track. You can buy a WIFI or Bluetooth module, but I found the box to work everytime, Chris

Another 5 star product from hobbyking. Good overall quality, very light and well made esc. Powerfull fan! Awesome value! I used the hobbywing software to make settings and usb adapter. Forget branded names. You don´t need branded names, I have 20 hobbyking combos at this time, they are keeping better and better. They are excellent!!

love this and the 60A x car esc's , we all know what they are but that should not detract from the fact that they are awesome , super adjustable from very quick to rather slow or anywhere in between, get the usb dongle or hobbywing LCD/turnigy LCD usb programme boxes and set up and change firmware on your pc, not waterproof sadly , no wonder they keep selling out .;-)

Nice Esc, i'm using it with my Xcar 10,5T Motor in 1/10 Touring Car with Hobbywing's V3_110930STOCK Firmware. After 5 minutes of race, Esc it's 35ºC and Motor it's 60ºC. It works very nice, run smooth and its small. Great Work HK! ;-)

For sure, a best bargain price for 120A Car ESC~ with well with Hobbywing firmware & 4 poles motor. Maybe, wire updated to 12AWG is required when the motor draws high amp!
