when building an 1/8 scale nitro buggy, i'm thinking high speed servo for
the throttle and high torque for the steering.

how many ounces of torque would you recommend? i see everything from 80 to
200.

the Futaba S9402 is a high speed servo with .13 sec of transit time and 89
oz torque with 4.8 battery. this sounds like the best of both worlds.
would that be powerful enough? should i look for more torque? the track i
race on has several jumps and i dont want the thing to be too delicate.

once again, im sorry for bugging the tar out of everyone with these
questions. i just want to make sure that the buggy i build will be able to
hold its own for some time without me having to start replacing this and
that right after its complete.

thanks again.

oh yeah, pretty soon im going to ask advice on the 8ight vs. RC8 vs. Mugen
MBX5-r, but i'll save that for another month

Figure the higher torque numbers are for monster trucks.

That is close to the one I run, although I don't race. Either way,
you'll still be better, no matter what servo you choose, running a 6v (5
cell) battery.
Personally, I use better high-speed servos for steering on buggies, and
high-torque servos for steering on MTs. I use the HS-925MG, which is a
Hi-tec brand servo, , it's nearly the same rating as the s9402, but a
bit faster. I'd compare prices though, but they're probably close. .

You are, IMO, correct in the high-speed servo for the throttle/brake. .

Can't help you there, I buy my buggies as used rollers off ebay, since I
can't drive worth crap and am gonna wreck them anyways. .
