Looking good! Does the position change of the arms impact it's control a whole lot?
I need to get some more flight time this week, but sort of wanting to flash new firmware on the board first... though it appears I can't find the
proper firmware for the cheap Chinese flashing tool I have.
If you have a USBtiny the flashtool newer than 0.33 and older than 0.63 beta 11 will not work with until you replace the avrdude.exe and avrdude.conf in the folder /lib/avrdude/windows/ with the one in this download
So, I think I need to do that and try again. Looking forward to better self-level calculations. I was having issues with the quad continually drifting forward in self-level mode, so adjusted the trim pitch to a positive value as it was set to the stock value of zero. It seemed to be doing much better. Then out of nowhere it seemed to be set too high, as it'd drift backwards slightly and was over compensation. So re-adjusted, would hover, would drift, would re-adjust. It got to the point where it was back to zero (where it was originally, and where it was drifting forward) but now it was drifting backwards. Entered the negative values. Balance hadn't changed, I've got the the battery secured so it hadn't shifted or anything. Wonkiness. Also adjusted the trim on the radio, although everything was zeroed out on the board properly as it should have been. <shrugs>
I hear the Stevie's firmware update is much better and handles self-level much better. Hoping it'll be an improvement over the stock KK2.1.5 firmware.
I need to spend more time with it and more time reading up. It does fly pretty stable now compared to the first few flights, but still not as well as I'd like it to (yet).
