It'll be OK when the power is on, but you shouldn't really be trying to
get more speed at the expanse of power on the collective servo. Using
100% ATV on your collective channel, work out the length your servo arm
needs to be in order to give full collective travel with no binding and
that's the correct length. Any other way is compromising something.
>should I get a higher speed servo,
You could, but I don't know why you'd need to. The 511 on a Baron 30 is
PLENTY fast enough for collective.

There IS a budget solution in the form of servo's that go under the name
of "J/P SuperTec" They make various servos having different speeds and
power so at least one from their range should get you what you want.
