Sorry, but you lead to more questions

Where are you using wood and fishing pole? From the picture the only fishing pole obviously visible is the flag holder (not saying I don't believe you, just curious how you used the rest).
The reduction out of the AM to the wheels is 1.25:1 (15:12). Probably just seems faster because of smooth drivers.

The fishing pole is the flag holder, its light, flexible, strong and won't break easily when entangled. The wood is used on both the gripper and main frame. In the gripper, blocks of wood were cut to fit tightly inside the 1"x2" tubes and hammered into the tubes the pivot points to provide reinforcement. This allows us to bolt the shafts on with a lot more strength and reinforce the bearing holes. In the main frame there are blocks of wood cut from 2x4s that fit between the main rails and the outside plates. The wood acts like aluminum standoffs but is far stronger for a similar weight and was attached easily with wood screws. The large size of the blocks of wood gives better stiffness under moment loads than smaller standoffs (very large moment of area) and at ~1/10 the density of aluminum doesn't weigh too much.
