I didnt think retractor servos was proportional.
Its full turn or no turn I think

It says "Retract" servo on it. It only sweeps from one side to the other, not left and right like a normal servo would go. If you want a "low profile", fast and strong steering servo for the little guys, then the Futaba 9551, or the older 9550 would be the ticket. Ron

sure is,I missed that,it is kinda slow though.

Overview

The A7000 retract servo is fully proportional and endpoint adjustable for easy setup; and when paired with the correct transmitter, is speed adjustable, as well. With 260 oz-in of torque, the A7000 can retract any mechanical gear, at whatever speed is needed

okk its slooow, but still lots of torque at 30 dollars...crawlers don't need a ton of speed anyways, were talking around half a second to get to full throw, not a huge deal for someone on a budget, and on 1.9 i doubt it needs anywhere near 160* of throw.

Ever wiggle your way out of a bind or down a ledge? Speed helps more than you think...

I do wiggle but not often, i have tricks i do with my throttle which is allowed because of how i built my radio and the nature of worms. probably why i don't see it as a huge problem.

It might be a good servo to mod into a winch.

yeah but its 1.2 for 160 degrees, isnt normal servos given in much lower degrees, if so its speed would be proportionally faster...

Yea but it is still slow.

A Hitec HS-645MG is 0.20 sec. /60 deg

If you do the math this one is 0.45 sec./60 deg

A little under half the speed. I would say that it would work well as a shift or dig servo if you are trying to find something small and strong as long as it didnt have to move too far. Hell slap a long horn on there and you would have more linear movement for less radial movement.
