That's the one I thought he might be running. I've been running a Spektrum 6040 which is the standard size high speed. Only thing that is a pain is that it is a hair too wide and does not bolt in on both sides. I use a single screw and double stick tape to attach it to my RC15R5. I kind of like the weight of the standard size up front. I only ask because I'm thinking of picking up one of the new RC12R5.1 and doing the Li-Po conversion, and with that conversion it appears you "have" to have the mini size servo.
