Default buggy servo?

okay i got 2 hv hitech 7940 servos and 1 7950. and at 7.4 the 7940 are rated at 222 tq and .5 speed and the 7950 is .13 speed and 400 plus tq. my question is shoul i run dual 7940 servos or put the super tq servo up front? because ive always ran the hitec 5955 and thought that a faster servo might give me a feel of more steering.. what would you guys do thanks

You want as much torque on your steering as you can afford, the steering takes a beating, remember the steering servo as to deal with jumps, landings, ruts, turning under power wile going thru ruts, a faster servo might give you a faster steering but might not last as long as a torquey one and a torquey servo will hold you input better.

Watch out on the 7940. It looks like the gears can't take the speed. The 7950 is good though.

if your a beginner i would highly recommend not getting such a fast servo. they make it hard to drive. i run pro buggy and truggy and i still use a 7955 which is slower than the 7940 also i do not have it to a 100% speed. i have driven a few buggies with the 7940 and i hated them because it was way to twitchy. i have seen people get them and they cant drive because of the twitchiness so they go back to a slower servo. i use slower servos on both throttle and steering because its not so twitchy and because i see people do worse with faster servos all the time so i think its a waste to spend the extra money just to get a faster servo and most fast servos have lower torque also.

my 2 cents

well i run a fast servo but with 138oz, of (torque on the steering) i just turn (down the steering expo,) and its not that bad, but i proberty need to turn it down more lol. as for throttle i do have a ,(quick servo its about .11 secs) and its diginal coreless servo. it can get you in troble, if the track is real dry but its good to have when your in the air, and need to (blip the throttle quick to) get a good landing.
