Hamburger wrote:how to attach wires to blueseries 12A ESCs? Those have no pads and I cannot solder to the tqfp atmega8 pins directly (no appropriate tools and insufficient eyesight even with mag-glasses). I had hopes something like a socket type thing would exist that could be used - but came up empty.
#define TIMING_ADV 0|1|2|3

I think, slightly increasing timing you can regain power loss, but probably in expense of efficiency.

Do you know this list of ESCs https://docs.google.com/spreadsheet/ccc ... ZRlE#gid=0 ?
It is not complete, especially about P/N and N-only variants, but may be helpful.
Mystery20A_nFET seems like a good start. It definitely is for an all N-FET type. With the list for the SimonK firmware, having or not having a crystal seems to make a difference. The Mystery20A_nFET do have a crystal.
But I do not know, better ask the man.
You were right it works with Mystery20A_nFET.
- from flashed ESC
- the stock ESC?
It is not recommended to use this option with ArduinoPWM input method (or should carefully be tested on the ground) because this method has low tolerance margins and the overclocked RC generator working on 16Mhz has significant variations. The usual symptoms are:
•Esc not arming.
•Stops at full throttle (it is hard to diagnose with MWC as it reserves some throttle, it is better to use simple arduino sketch to test it).
Also over clocked RC oscillator has lower thermal stability.
(yes|no) – On boards without external crystal, the internal clock source (8 MHz) must be used. Due to manufacturing tolerances, it's possible to calibrate it with an external program (e.g. PonyProg?). The calibration value is stored in the EEPROM and can be used by this firmware. It should be disabled on boards with external resonator or when OVERCLOCK is defined.

Is it just me or is the whining noise from wii-esc @ 8MHz worse than with original firmware (which runs @ 8MHz as well, afaik) ?

However I've found the quad to be overshooting/ hunting and somewhat unstable with re-flashed high performance esc's (otherwise the same combination flown before), can someone suggest a more suitable default set of PID's to start tuning from, i haven't really mastered PID tuning yet
Operating Current: 4A ~ 12A
Peak Current: 15A
Suggested prop: 9x4.7
Dimensions: 27.6 x 28mm
Yes, I did read about creating the hex file. But have problems with it. So, which files I need and so on.
Do you have a number for the actual max. current your motors draw?
