I having been having a bit of trouble with servo failure on the aileron
servo of my Raptor 50 I have set the servo's and rod lengths as described in
the build instructions. My question is on full travel no binding etc should
I be using the transmitter to stop the servo going to far as to create kick
back effect on the swash plate as the rotors turn, hope this makes sense how
I have described it.

When you say "no binding", do you mean no binding of the swashplate itself,
or no binding of ANYTHING connected to it when the swash is at full pitch
AND full cyclic deflection?

There shouldn't be any binding, knocking or stiffness when the blades are
rotated with any combination of collective and cyclic. If there is, reduce
the cyclic and/or collective travel until there isn't or you'll continue to
destroy your servo's.

Cheer Beav yep I meant no binding when stationary in any direction, but when
rotor turning and on full deflection either left or right it kicked back
slightly at the servo as it turned which is what I thought should not be
happening even at full stick,

Thanks Rob

And you'd be 100% correct, even though it's rare that both sticks are at
full deflection at the same time. Rare, but not "never", so a reduction in
servo throw is definitely the answer.

As always, it's my pleasure:-))
