I have flown the Velox with both the P-70 and K80 and also noticed the K80 seems to also carry less residual thrust, I was able slow the Velox down easier when landing. Otherwise the K80 and P-70 are very similar in performance.

As to throttle acceleration/deceleration time the stock factory set parameters seem to be fine for my "pattern" and "scale" style of flying as Iam not really snapping the throttle open and closed so it feels quite linier to my throttle stick movements. I have not felt the need to adjust the factory set Fadec acceleration parameters.

As to blowing plugs, I think this maybe relative to the battery type/capacity being used. Iam running six cell NiCad 7.2V 2400 mAh packs for my K80 systems and have not blown a plug yet. Check with your Kingtech rep if you are blowing plugs and ask about your chosen ecu batteries compatibity with the stock Kingtech Fadec parameter plug heat range settings.
