my 22 broke two sevo's is one night?

[racer11]

the first servo came stock from a b4.1 and as i left a spacer on the mounts the servo was pushed further forward than it should have been and bust itself when it got jammed with another arm after a nasty landing,

the second servo was an old futaba one kindly donated to me in pity as 2 laps into the meeting i had no servo so i put that in without the spacers this time and it went great for two laps then on another ichy landing the wheels locked and i had to leave the race. what had happened was the servo arm had been pulled back and then bent the wrong way, so toward the chassis rather than away.


i think they were both plastic servo's and i want to know if a metal savox 1251mg servo for instance would stop this problem or could it be something wrong with my set-up?


thanks
