Got robbe fs250 t digital servo's in my raptor 50.
at first they sold a bad stock so al my servo's were replaced for modified
one's by robbe europe(new ones).
the old ones could suddenly die.
gues what, if have flown for 1/2 a year or so with the new ones , did some
hovering and flying around a little , and then without warning my roll servo
died. luckly the heli servived it, but i do not trust them anymore.
Anyone with the same expierence out there with this type of servo's?

I use them in my Raptor and I found that the plastic part in the main gear
that turns the potmeter is not glued or mechanically locked, they are held
in place with friction only. It will turn with a little force and this will
upset the trim. I was constantly trimming and changing the pitch range until
I found out that these servos had this problem. It seems to be solvable with
a drop of CA but it is a bad design if you ask me. I will never buy them
again.
