This might be a stupid question, but all the wires are black and I'm not sure which wire I should connect to which color on the motor, any tips? Thanks

It wont matter which way they are connected up. Do the connection, test that the motor direction is correct for your application. If not, swap any two wires over :) Hope that helps

Just got my Blue 40a ESC. DIDNT see the comments here from the USA link. I was able to get the Brake to turn on/off, but cant get the Soft Start to disable. Who knows about the other settings with out a lot more testing. Seems like it shouldn't be sold as PROGRAMMABLE if it isn't. or if the methods have changed then update us!

I just solved this last night. There are no instructions but if you first have esc unplugged then turn transmitter on and have throttle all way up then plug in esc and follow this you will figure it out. You will have to check off where you are with the tones and have a motor with prop off for safety sake. I had to turn soft on to use it in a heli Factory default settings: Brake: off Battery type Detect: LiPo with Automatic Cell Low voltage cutoff threshold: Medium (3.0V/65%) Timing setup: Automatic Soft Acceleration Start Up: Medium Governor mode : OFF Frequency : 8kHz Low voltage cutoff type: Reduce power

Mine came with instructions, and that was never an issue. It was a fact of it not accepting the programming, not the fact I could not figure out how to do it. But the conclusion was that my ESC doesn't have a true Linear Start function. It looks to have been factory programmed with 3 soft start settings. All other functions programmed successfully. HK support was great and we got it all worked out. I do not know if my issue was isolated or not.

I can confirm that the ESC can not be programmed. I tried with the Hobbyking programming card but it was completely dead. Now it does only work with the default setting.

Sorry but it is programmable

5 thumbs up!
Wow, I am glad I bought this when I did! This is a fantastic speed control. I hooked it up to my new HK 450MT project and have had no problems. I haven't gotten the chance to really load it up yet, but it runs cool in hovering (test flights).

I deducted one star because it comes with no instructions. While you can build the HK 450 with T-Rex instructions, I wouldn't attempt programming the ESC with them!

Thanks again, HK!

Best ESC so far, will not use others for the time being. Very easy to program with the correct programming card.
