Hi guyz,

I need some help for my device. Right now i am working on a tank using NXT sets and snow mobile technic set for the tracks. The device move very slow. I mean extremely slow like moving 20cm over 5 secs. Is there anyway to make it move faster without losing the climbing ability? like replacing the motor or any self mod thingy? I want it to be able to climb like 5 cm height. For your info, im using 1:1 gear ratio and the device now is capable to climb almost anything as long it won't topple upside down.

Please help. Your help is very much appreciated ~!

increase your power in program or change the ratio to 2:1 or decrease to weight of the tank.
i hope this will help

Is there lots of excess lego parts on your tank? becuase weight can be a huge problem, so if you remove any bits thatdont need to be there that will help.

are you just using the normal NXT servo motors?
if so, do you have them set to 100% on the program, and make sure ur brick is either fully charged or with new batteries in it

sorry for the EXTREMELY late reply
