Quote from: Balders on Thursday,December 13, 2012, 12:14:25 Hiya, I';ve only got a minute, so excuse the quick nature of the reply.The stock PID settings after a V1.5 flash seem just about right for my basic quad. The original firmware goes bonkers because it was set on simonk flashed esc';s but 1.5 assumes "standard" esc';s and works like a charm.Yes, the esc throttle calibration is deliberately tricky to stop you doing it accidentally. You can just about do it on your own but much easier if you get someone to hold 1&4 for you.As to how long to hold throttle up, it';s only very short time. Throttle up, power on with 1&4, probably get three beeps, throttle straight down. More beeps, this time sounding like it normally does on power up. The most common mistake people make is keeping throttle up too long, which will put the esc';s into programming mode, which can cause all sorts of fun.Hope you get it figured out, love my little KK2 quad (and also tricopter).Next thing is to set your self level...again V1.5 really gets it snapping level...it';s very impressive for such a cheap board.

QuoteOne more ESC tested (IIRC info on google sheet is incomplete, so maybe add info about external osc and flash?) - Mystery Cloud 30A. Bought from ebay (note - picture shows Pentium, but You get Cloud). External osc, no pads (but easy to solder). Double heatsink (both sides with heatsink, after flashing i left only one - no need for BEC anyway). Used tp.hex. Flashed 5, all working OK so far (only tested on ground).EDIT: tested in air on quad (holding in hand) - one motor sometimes stops for second, then restarts. I think, for quad that would be deadly - it would flip over.EDIT again: swapped "buggy" ESC (i ordered 5, needed 4), so far - no problems. Looks like problem with ESC, but appears rarely.
QuoteI';ve just finished testing the mystery cloud 30A Electronic Speed Controllers (If I Remember Correctly the information on the google excel spreadsheet database is incomplete, so maybe add more information about the external oscillator and the method used to flash the ESC if possible?) I bought it from ebay (note the picture shows the Pentium speed controller but you get the cloud). It comes with external oscillators and no soldering pads, but it';s easier than some to solder to if you want to try. It has a double heatsink which means that both sides of the ESC are covered by a heatsink, but after flashing i left only one of the two heatsinks in place. The other one covers the BEC circuitry rather than the MOSFETs and wasn';t needed anyway). I flashed it using the tp.hex firmware. I flashed 5 of them, all seem to be working fine but have only been tested on the ground so far. Update; I';ve tested the quadcopter in the air by holding it in my hand - one motor sometimes stops for a second, then restarts. I think this would be disastrous for a quadcopter in mid flight as it would flip over and crash. Update no 2; I swapped out one of the 5 electronic speed controllers, it seemed to be faulty. The other 4 work fine so far, no problems at all. It looks like there was an intermittent fault on the 5th speed controller.
