Hi Guys, I finally got my newly built quad out for a test flight yesterday, set up is as follows:
X650 Carbon quad
APM 2.5 (currently no GPS fitted as it stopped working)
Tiger MN series 700Kv motors
3S 6000 mAh Lipo
I was pleasantly surprised at how stable the craft was and there was clearly plenty of available power. However, it became clear (particularly when it was time to try a controlled landing) that the throttle was very difficult to balance. The craft would either drop quickly, at which point i would input some throttle, then a bit more throttle, then it would climb quickly, so i'd back off the throttle, and back off some more, and it would drop again. It was very difficult to balance the throttle to get the craft into a controlled decent.
I finally got the craft back down to earth in what you might call a controlled crash. It's clear that some adjustment needs making to the throttle PIDs, but i'm not sure which, or which way to adjust them.
I'm using the latest Mission Planner, and my current settings are (default I think):
Can anybody tell me what i might need to adjust, and which way, in order to smooth out my throttle response? I think at the moment the problem is that the throttle response is too sluggish, but i'm not sure how to correct it. Any help greatly appreciated.
