Hello
I have owned a apm 2.5 for nearly a year now first on a turnigy H.A.L which was a mess and made me lose all hope in apm after months of trying to fix it.
then i made the decision to change the frame to a f450
and to my surprise it did wonders it managed to fly(sort of).
I had trouble with inverted compasses , failed radio calibration, vibrations and more.
I managed to fix these however i could not fix on thing,
it drifts all over the place in stable mode
and not your normal wind drift,
it will speed up quickly while going to the side.
autotrim only made it worse and it will drift to the other side
so i tried to manually trim it.
when i trim to the right it will first overshoot to the right and then go hard left again(if it drifts right it will do the same if i trim left)
in loiter you can see it struggle against the drift(it wants to move to the left)
my copter can't hold alt very stable,which i think is a result of the drift.
quadcopter specs:
multistar 2216 800kv
30a afro esc
12x4.5 prop
f450 frame (originally turnigy H.A.L)
2x 5000mah 3s (i use a second one for added weight otherwise it is very overpowered and bounces around
without a camera)
apm 2.5(3.2)+gps/external mag+power module+bluetooth telemetry
flight time 22min(longest flight i did )
the quad is level in mission planner and real life
all trims are reset on my tx
all esc calibrated all motors run in sync
all calibrations done multiple times(compass, compassmot, accel ,radio)
did autotune(very smooth response)
treid auto trim and save trim did not work
vibrations are between 3,-3
i hope some one can help me
i managed to fix all those problems
but not this one and i am desperate :cry:
thanks for reading
Colin
will add log in a minute
