I have 2 units of this brand and model that are not working, it seems manufacturing defect, and returning them to HK will just cost me more that what i can have in return...

Hi willy... love that choc bar lol. Make sure you only have 1 bec hooked to power. If that does not fix it try one at a time, check your battery as well for voltages. if below 3v it will do nothing. It is possible as well that the factory set that voltage higher than 3 v or 65% so if you have calibration experience you might try to reset that to factory specs. ? There are lots of videos on youtube showing how to do this. Hope it helps Dave

Hi willywonkaRC, make a video showing them not working, upload it to youtube, and then make a claim through HK Ticket system. Often times when you can show the items are faulty they do not require you to return them and will ship out replacements or refund your bonus points balance.

Hi Nick. It doesn't come with any connectors. You'll need these PRODUCT ID: AM1009x10 to connect to the battery pack you mention. cheers

What 30A brushless ESC do you recommend with the Bix 3 using a Turnigy 2200mAh 3S 35C LiPo and a 2630 kV1400 stock motor?

The HobbyKing 30A BlueSeries Brushless Speed Controller would be a great choice. I have had a few myself, and they worked perfectly until I got a motor that needed a bigger ESC.

PIXHAWK compatible: Have 5 of theses on a Pixhawk controller. 2 work perfectly and 3 "bad ones" won't spin up. The three "bad ones" work perfectly everywhere else. Checked the signal voltage is 3.3 volts, the PWM pulse is 1 to 2 millisec at 400Hz. They calibrate ok. Programmed to the "factory default". Even runs fine on a pulse generator where I can vary the parameters. ANY IDEAS? Thanks
 daddski 42 points
When you use more than one at a time it is important to make sure you cut the obec power lead red wire. You only need one bec working at a time and more than one makes the esc's "fight" each other for control and hence a few will not spin up. I had this issue using just two in a b2 spirit. Hope this helps. Dave

Hi guys, i got problems with this ESC, they are not saving the calibration after exit the Calib. mode. When they are inside the Calib. Mode they take perfectly the calibration and the motors run great, but when exit the mode and arm the APM they just runs like nothing happend. (Not Calibrated) I allready calibrate the 6 ESC independently and all at once, with APM and without APM My question is: is the APM capable to create this problems or is something else?...i really dont want to flash the firm to Simonk. Thanks guys

Make sure that you are actually "saving" the new instructions when you exit calibration mode. if that doesn't help then you may have to flash them . Best to you

I put two of these in a Dynam A-10 with the stock 64mm 6 bladed edf's & a Turnigy P2627L EDF Outrunner 4200kv for 55/64mm with a turnigy 3000mAh 40c lipo. Esc's are giving out 34A at WOW & come down a little hot on hard flying but are doing the job and keeping the plane really low on weight. great price I love these blue babies, go for it. I will by buying more!!!
