You need to give us a little more info on your problem.
What servo and horn are you using !
How is it breaking ?
( on landings or hitting corners etc )
I've been racing the SV2 and KF and as yet have not broken a servo or a horn.
Have you set you EPA's so it's not stressing the servo with over throw ?
As for set ups, try Toms !
