Recently I bought a 450 XL CCPM and just finished building and setting it up. I took it out to hover it and
see how the trim etc is setup and as soon as I got it in the air it was like
I had almost no control of it. I set up the ccpm settings on my DX6 Tx this
way: ccp2 45% ccp3 45% ccp6 55%, but I didn't have enough throw. I was
cranking full left right fore aft cyclic and it was barely enough to make
the heli do anything. I barely managed to land it on the ground without
breaking anything except a skid on one side due to a very hard landing. So I
took it home glued the skid back on and went out to the end of our
cul-de-sac here. I added more % to the ccp control. This time I had more
control of it, but still didn't like the way it handled. It was very twitchy
and it wouldn't respond to my inputs until I was at the end of the stick
throw. Then when it finally responded it was very quick to do what it should
have done when I initially made the move. Also the swash doesn't
center/level perfectly after I let off the right stick. When this happens
the servo's just hum because there is still load on them. I am thinking of
buying some new servos, but the thing should fly fine with the servos I have
which are s-75 servos that came with my DX6 Tx. Another thing I was
thinking that may be the cause of the centering issue could be the fact that
all the ball joints are still a bit stiff. At neutral all the servos are
centerd and the swash is level. Any opinions on the issue?
