Finally sorted out flashing the last ESC with SimonK software. WOW what a difference. Flight is more stable for sure, haven't broken anything this morning. Ended up binning the kit ESC that wouldn't flash, ordered a new ESC (HK SS30A HW) and flashed it by soldering (not the HK flash tool, it's a piece of junk).
Also replaced the kit motors with Turnigy 935Kv Multistar motor and prop combo for a little over $13 a motor. Now cheap is cheap I know, but comparing these two motors is like comparing a Lada with a Suzuki (can't go as high as a Toyota or Nissan). Some may argue that a Suzuki is not as superior as a Lada
, but the quality of the new motors is far superior to the kit motor even at the low cost.
Also dialled in 20 on Throttle Dampening in MISC settings because every time I yaw on the rudder, the quad drops about 4 feet, and a little less with elevator and aileron. I stepped this up in increments of 5 starting from zero, and I'll have a bit more of a play around with this once I have some juice back in the batteries.
I have to order a head strap for my AEE Magicam so I can get some footage before I take the leap into FPV and BEYOND.
