Ok, I'm running an out the box RCTimer ASP (RCtimer martinez controller, v49), with a nex5r, standard lens. It's fed from a 12V BEC (Gryphon).
I've got roll totally locked in; no vibes, instant response, no lag, no over-compensation. On the tracking screen (front page of the tool) it barely moves off the baseline, even at maximum zoom. It's spot on.
The problem is pitch. I can get a rock solid response from it, just like roll...but it buzzes/vibrates badly. Scale back "D", and the vibes reduce...but now P is too high. Scale back P...and I've lost the responsiveness - it "judders" in rotation, or just gives up altogether! Scale up power to compensate...and the vibes come back. Swap it around...scale back power and ramp up P, I & D incrementally...vibes and poor response. Tuning D seemed the most effective way of reducing the vibes - but there is no happy middle ground between vibes and "too much P" oscillations. Not even a 0.1 band - it's vibes or "P" oscilations. You normally get a small "sweet-spot" between the two, but not this time.
Spent 3 hours last night balancing, rebalancing, starting from scratch on pitch...and I just can't get it. I can get it vibe-free, or fully responsive...but not both. I tried using the IMU filter, but it had "lumpy" response in both axis. The timing option as well made no notable difference.
Anyone else had problems like this on the ASP with martinez? Any tips?
