Ive flying FPV for around 2 Month with a RTF 3.5 Quadcopter.
Today I put my first self-built 3.5 inch quadcopter into operation.
Foxeer Mega 3.5 Deadcat
HGLRC F7 Aio
GEPRC 2105.5 - 2650Kv
6s Lipos
Runcam Nebula Pro
Betaflight 4.4
Except for the small problem that follows, the copter flies very well with Betaflight standard settings/PIDs + filters and my usual custom rates and much better than my pre-tuned RTF 3.5" copter.
The problem: despite the same rate on the roll and pitch axes, the copter does the 360° flip in the pitch axis a lot faster and overshoots to much. Roll axis 360° is perfect.
I used different batteries for the test flights. 650maH-6s / 1050maH-6s.
This problem exists with the 1050maH LIPO. Rarely or not at all with the 650maH.
For a similar setup, the frame manufacturer recommends to use for Lipos 650-1000maH.
Why is that? The higher weight of the 1050mah batteries? Or possibly the Deadcat design?
For me it feels like a problem with higher mass in conjunction with the Deadcat Frame
Should I just turn the rates down until the pitch axis feels the same or is this a PID tuning thing.
Thank you
