For 1/10th offrroad buggy racing, specifically 21.5 stock class. Would it be better to have a "high torque" servo or a "high speed"? I don't really know the ins and outs of this topic. Any opinions are much appreciated.

Neither. Some of us just prefer the way some servos feel.

I avoid car branded servos. Would rather get from a servo company. Hitec 777 and Tekin 250 are hot IMO.

There's a bit of a caveat to your question. If your servo has 5 oz of torque, and the servo is 0.001 sec/60º, its worthless. Conversely, if you have a servo with 600oz of torque but at 1.0 sec/60º, that's also worthless.

I generally aim for a minimum of 175 oz of torque, and no slower than 0.12 sec/60º speed for a 2WD 1/10th buggy.

The servo I'm currently running is 319 oz @ 0.08 sec/60º (@ 6V), but not everyone is willing to spend that kind of cash on a servo. The Protek 160T is a decent servo for the $100 it costs.

BTW, you may get more answers in the radio/electronics forum

To answer the question you actually asked, I’d pick the 1606a for your application. It’s got more than enough torque for a 21.5 buggy, and you can always dial back the steering in your radio if you have a decent one. The higher end Reedy servos are great, and outperform and outlast some of the others mentioned above hands down.

I've spent years running the protek 160T servo in almost all my 10th scale vehicles. Recently, a friend mentioned trying the 140t. A hair slower and when you turn the 160T down too far it get's notchy. The 140 has a better feel for some. I bought one to try, but it has the torque, it's low profile and it's plenty fast. I'll still need to turn it down a little I'm sure.

I look for 175 oz of torque, replaceable gears and a 1 year or better warranty. I have some MKS I really like too, but they are all too fast.

Both . I generally aim for under .1 second and 150oz torque AND full aluminum body. You can cut cost by going with a plastic top, but it’s more prone to breaking. Also an aluminum servo arm helps with durability.

i usually go for <0.10s / 60 and for 10+ kg for most servos.

I can't imagine what others go through to dial in center. Just hook the tekin to the hotwire and reset center, done. On track with zero trim adjustment in transmitter.

I've personally been fine running the T120 and T180 in buggies.

I run red box specials off of ebay or Amazon. I like the "pro" version over the regular.
I get the 20-25kg ones. Gonna try a 35kg one on my shortcourse truck and take out the protek 100s that's in it before I totally waste it. Lol.

Related to Reedy servos - anyone know if they are SSR compatible?

It's not listed on the specs for any I've looked at - so I'd say no (I'd be happy to be proved wrong though as it would be a great feature!)

I get a kick out of people saying they turn the speed down. the faster servo just reacts faster to your Tx inputs. move your hands slower. no such thing as too fast a servo. I guess its all personal preference.

Or u could just buy a servo of the correct speed and not waste money.
I get u get what u pay for though. in mod its better to buy a higher speed motor and turn it down so.

I was looking at the reedy servos (RS1606A and the RT2007A). I am going to use the exchange program for a servo and motor. I appreciate all of the help.

FWIW, any Pro driver you talk to will likely tell you the same answer in off-road: All things being equal, get the torque version. Even then you may still benefit by reducing the steering speed in your radio settings. 9/10 times this is one of the first items of feedback when a top guy drives one of my cars. Along with "turn down your throttle EPA"...
All those fancy settings in the radio are useful and there for a reason. Not saying to use every mode/limiter/aide/curve that your radio has to offer, but don't be scared of digging in and understanding how they might help.
