odd... my clone can push the green gears FAST>.. it gets top speed in about 3 feet... which is unbelievably fast... are you sure the gears are meshing properly, and not rubbing the chassis? try turning the axle with your hand, see if any resistance is there...

also, remember to use a very high torque motor, and the 7 tooth gear....

the blue gears should be twice as fast as the orange gears, green even faster..... !

i know my stock bit with a KIT 2.6 WILL turn the blue gears, but wont be fast at all..
