I don't like flying with all of the SPI programming wires hanging off the ESC; concerned of shorting something with a broken wire in a crash.

This is a the first I've seen something like this. Are there other such devices? Anyone using something similar?

Pretty slick, most people make their own.

Hi,
I just got 1S/7A ESC from HK, but I have a the same problem.
Could you tell me where you soldered the cap?
I tried several options, but the result is the same - the motor doesn't start properly.
You mention "on the resistor divider network" - what exactly does that mean?
thank you

I circled it in red.

I don't know if others do this, but I didn't like the main esc shutting down without also shutting down the tail. I lost 1 tail rotor from this. I disabled the low voltage shutdown in the esc and just let the 3-in-1 shutdown the main and tail through it's control signal. I think it works better that way. Latter version of the BLheli code do have some degree of voltage threshold settings.

I am trying to build a helicopter controlled with ipad via bluetooth 4.0 instead of classical remoter.

The problem is that ESC has to be calibrated through remoter at the first time. I want to set the throttle range just in the BLHeli program, anyone can help me with that!

Thanks a lot !

The SiLabs version of BLHeli has been developed a lot further than this Atmel version: http://www.helifreak.com/showthread.php?t=390517
There throttle range is programmable for PPM (standard 1-2ms input).
