The 358 or even the 357 are both killer. Is this for 10th or 8th scale? Another option is the JR 9000 series, these are SUPER fast .06/125 and I think the 9001 is like .06/180. Might be wrong on the torque, but correct on the speed. I have and still do to this day use the Airtronics 94357/358, well now the 94361/362....the 361 is the high torque one, basically the same as the 358 but with heat sink housing. NEVER had one go bad on me and tracks straight always. I don't ever use Hitec, so I won't ever recommend one. I had one very bad experience, though years ago, still won't bother with that brand. I stick to was has been proven to myself. good luck man. Later.

OK bro, you definitely don't need the 358. I would recommend the 357, it has 125 torque and .07 sec/60 degrees. Or if you want the digital which is very nice for the steering, the JR 9000S is perfect for you with 125 torque and .06 speed.

The digital servos are suppose to center back to center better and have a stronger holding torque. They tend to use a little more power then the analog like the 357, but not really enough to notice. Just keep an eye on your battery charge like normal. Should have no problems.

Me personaly would not go below 100 inch/oz of torque for the steering. But I like that extra torque, better then not enough. 85oz of torque is probably enough, but I've never ran a servo this low. 125 is the lowest I have gone and I still can get 1 hour out of a charge if I just happen to run an hour main, which never happens. So there you have it. Your call bro. Ask if you still need more advice. Later

I would recomend airtronics 94360 for the steering it has 125 oz tourqe and .07 on speed! For the the throttle run the 94359 it has 200 oz of tourqe with a speed of .10. Its best to not have a super fast servo for the throttle, but you want the fast ones for steering! Both of these servos come with heat sinks. Good Luck!

I like the Airtronics 94357z for on road and the 94358 for off road. Good holding power and pretty quick.
