How important is servo speed for crawlers/trail rigs?

[sumguy75]

Just thinking about how often small careful motions are needed when climbing something at the limit of a rigs capability. Would a high speed servo take away from being able to make those careful movements? I'm still fairly new at this but seems like lots of torque doesn't have a downside, but lots of speed might?

I lean towards waterproof and higher torque.

Same here. Go for more torque, and don't worry about speed. But it's ok to have a fast servo on a crawler. The steering wheel is pretty sensitive and fine adjustments with a fast servo are easy enough. You're likely not going to notice it much on a crawler.

You won't be making any super fast turns with a crawler so high speed isn't needed.

Haven't been at this long but, torque is more important. Speed doesn't help when you're stuck.

I don't think speed is going to harm anything if you already have a fast servo, but as stated above, not at all necessary. Torque is king in the crawling world.

Yeah buddy, torque, you want that servo to keep that wheel steering where you want the rig to go when you’re stuck in some rut/traversing tricky terrain. I like it when the servo can push the entire vehicle left or right with the twist of a tire.

I wanna add…. That a strong servo in my sendero hd was like night n day. The stock servo lacked the torque to keep the wheel turned sometimes when the vehicle was climbing.
A strong servo in my scx24 was well, unbelievable.

Servos these days are strong enough to bend steering links

Speed is useless in a crawler.seen noobs us a fast servo and drop right off a rail bridge .
Torque is what your after like all the posts before me say

Thanks for the feedback. I was looking at 2 servos from Hobbystar, torque is near identical but one is slightly faster and $10 more, figured the small jump in speed wouldn't matter so long as the torque is equal or more.

I’d go direct power on the servo but that’s just my preference
