Revo, hands down for the following reasons: I've seen the Revo,Savage and LST side by side, handeled them, watched them get thrashed. The guy with the LST was very disapointed, as it had constant issues with the a-arms and clutch. Although it did jump very well. It will be a nice rig once the issues are resolved.
The Savage is a very tough truck. It handles amazingly well for it's high center of gravity and would be my second pick .
After my observations listed above, I purchased two Revo's and broke them in as per instructions. Everything went very well, although we had to use a heat gun on one of them to get it started.
The Revo is amazingly quick for a .15! The tranny shifts very smoothly and the slipper clutch is easy to adjust. Only flaws I'm aware of are the shock rod ends being plastic tend to melt from the pipe, and the wheel nuts kept loosening causing the plastic wheel hub to strip, thus taking out the accompaning wheel( a brief call to Traxxas took care of that, new set of wheels enroute, no questions asked!).
To date we are amazed that the Revo's haven't brocken yet! We have been thuroughly thrashing these thing on a daily basis. I've put about a 1 gallon thru the two in the past three days, with zero problems other than what I listed above.
They have excceeded our expectations substantialy! I'm VERY pleased and would highly recommend them to you!
PS.
The guy with the LST bought a Revo and is very pleased!
