Help
I need to find the total throw of a JR Sport Servo, RT88. Unable to lcate this info, Tower, any place else I have looked gives me dimensions, torque, etc, but no throw. I am hoping it is 180*, but I don't think so.
Thank You in Advance

These are Sport Retract servos. Retract servos are usually 180 degrees and Non-Proportional. I switched from the RT88 to the 791 Retract servo, for my H9 P47-150, because they were too weak and I stripped a gear.

Cjtyped,
You will never find the spec's at Tower, since this servo is a JR (Sport) which is marketed by Horizon Hobby, not Great planes (Tower Hobbies).

Here is the Horizon info on the RT88

This is just a curiosity question since I do not plan to have retracts on anything, but I clicked the link to the servo page.

It says "Speed: 1.12/160 @ 4.8v, .90/160 @ 6v"

Does that mean it takes 1.12 seconds to travel 160 degrees? Would that mean total travel is 160, or is 160 just a standard for giving the speed number?

Retract servos are slow in comparison to other servos. 1.12sec is about right. The JRPS791 servo is Metal Gear, 1.55sec, and 260 Oz/In. They only work at 4.8v.

The 791 is 170 degrees. I believe the RT88 is similar, it is not a full 180 for sure.
