I agree with token. JR 9100T on steering and 9100S on throttle. 3 year warranty and great performance.
I run an Orion 1600mAh NiMH receiver pack. Good for about 1 hour of run time with that servo combination and a personal transponder. I've run 3-4 practice tanks, 3 qualifiers and a 20 minute main without charging. The 4 x 1 hump pack is a tight squeeze in the Losi battery box, but doesn't slide around.
