the savage 25 is a good truck. i've read reviews of this truck and it's very capable of jumping, high speed runs and is very durable. don't know if this truck could be used for rock climbing. what you need is an electric truck for percision low speed driving using the novak super rooster. with gas trucks, you can't do this merely because you need to put the engine in high rpm to get the torque out of it causing you burst of speed instead of a slow consistent speed...
