Hey guys, i fly a QAV400 with APM 2.5, ive noticed some odd flight characteristics such as when the copter tries to stabilize its almost rocks trying to do so, in a very fast fashion.
If i throw it full pitch forward, and let go it rocks before stabilizing. What could this be?
Also, another thing i find very odd or difficult is when i accelerate and pitch forward, the copter seems to drop altitude significantly.
Any ideas on these? Appreciate the help!

ok I did the work for you just click and enjoy....new PID soon to help...no need for a log...just experiment with them and write down your current settings and every single one you change to every time...KEEP A LOG...so that if you get off track you can revert to a known good point and start again going the oppisite direction.
