I just installed one of these on my Matrix TR FRE, after going through a number of Skyion 144oz servos and a slew of hitec 645s. I finally ponied up and bought the best I could find... even though my LHS was pushing the new JRs.

anyways, the new coreless design of the 7955 is awesome. This thing has plenty of torque and is also really quiet. It also comes with a billet steering arm. For 120 bucks, you really cant beat it.

Oh... I'm using a 925MG for my throttle/brakes. Plenty of torque for that, and its faster than a 945.
