Under or over weight?

[Zippiot]

i found something yesterday that surprised me...instead of using 1/4 aluminum plate it is 1000 times easier to use 1 inch thick lexan, it is also just as strong and about the same weight (plus its see through!) if i had known this from the start many of our mounts would be lexan, which would actually drop us 10 lbs according to my math. right now without battery and without a few electronics (just the board and speed controls) we are 86 lbs, but we used large wheels and even though the bot is very stable (almost impossible to knock over as i have found out) we are going to add some steel weights to the bottom to bring down our center of gravity. maybe a spinning light display too
