Sounds decent, but...

$70 is too much for so little torque for use in a crawler, but fine for most other applications where speed is more important.

For $10 more you can get the ProModeler v4 servo, with a speed of 0.12sec and (as the name says) 420oz-in of torque.

The ProModeler case is entirely made of machined aluminum, no plastic - and has steel gears instead of titanium alloy gears.

The XQ you mention would be best used in a 2wd stadium truck, or for onroad use where speed is more important - for crawlers having 0.14sec is plenty.

You really want at a minimum 300oz-in of torque, or better yet over 400oz-in for crawler use.

If it was rated for 7.4V it would also be better, because it's torque figure would be better at the higher voltage.

I like the way it looks, but have to second the Promodeler 420.
It really flies and is one of the smoothest and quietest servos I have ever seen. I'm running mine at 7.4v and puts my hitec and Savox servos to shame.
Promodeler also has one rated at 245oz.
John Beech makes them here in Florida
