I have a question. If I flash these with SimonK FW, can I still use the programing cart to program these?
 Anton 1 points
No, you can't.

Anyone flash this with simonk using kk multicopter flash tool? Which controller do you choose? I think I'm picking the right file to load: bs_nfet.hex
 Jonathan 1 points
Figured it out. Should anyone else be looking for the same info: programmer: USBasp controller: atmega 8-based brushless ESC (8kB flash) Loaded the correct file: bs_nfet.hex

Having problems with USB driver to flash 30a Blue Series. Has anyone found a driver for Window7 64bit?

can you please give information about connector types? (PWR/BEC/MOTOR)
 EffinA 1944 points
The connections are all bare (except for the servo connection), and the BEC is internal. I use 2.5mm bullet connectors for the motor wires, and an XT60 connector on the power connections. The BEC feeds power through the servo lead to power your servos and receiver. If you are not handy with a soldering iron, I recommend that you learn, or find a friend that will help you with that.

Thank you for your quick answer. I wanted to use this one on my quad. but I think I will use turnigy's ESC. it's only 1usd difference and it comes with all connectors preinstalled. maybe if HK will lower its price It will be more worthwhile

Understood. I fly fixed wing planes mostly (I have 2 quads), and for planes, these are top notch! Thanks for the credit!

I have just thrown out my Turnigy Multistar ESC and replaced the with these. The firmware on the Turnigy ESC is buggy, if the prop stops for any reason, it will not start spinning again until you push throttle back to zero! This has caused quite a bit of splintered carbon fibre here. The BlueSeries is great and works flawless. The BEC is made up of 3 linear regulators so on a quad you can connect all 4 BEC wires for additional safety.

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!!!
