I was told by more then one servo manufacture that in 1/8 off road we should use T's in both throttle and steering. Reason being is that 1/8 off road cars weigh more then any other RC car class, and when under breaking the Speed servos can't handle stress from the load. This makes sense to me because whatever servo you decide to use was prob not designed strictly for 1/8 off road application. My suggestion to you is. Contact whatever manufacture you decide to go with and ask them what you should use for your application.
Just my 2 cents....

There may be some truth to that. I have blown up 2 9100s servos in the last year.

This is why I have been running 7955"s for both. 333 oz of torque. Zero problems.

I use 7955's for both. I also have 2 more 7955's for back-ups. I just recently went un-regulated and it actually steers so much faster I can't drive it ......it is ridiculous.

I'm running the same type of servo on throttle and steering, too.
Ace 1015 - fast and powerful plus you need to have only one type of replacement servo with you.

+47 on HiTec 7955.

And, like Joey Platinum said he's doing, I run mine unregulated. No problems at all, and they're faster because of it.

The short arm will have more mechanical leverage and produce more torque but with reduced speed when compared to a longer arm.
The longer arm will have less torque but more speed. You'll only get this extra speed if the load on the servo is not too much that you bog it down.

On the topic of this thread, I don't think it matters if you match the servos for the same speed/torque because the servos on the throttle and brake have different servo arm lengths.

1) The angles the servo arms push and pull on the throttle and steering
are also different.

2) Loads are different....

3) Travel is different...

4) 5) 6) .....As it was said earlier... there are too many variables.

So its pointless to try and get the "feel" to match on both throttle and steering. Just dial it in to your preference with the radio. (EPA, EXP, SPD, ACC)
