weight in a car
If you have a car that weighs 53oz with nimh batteries (tc5 or cyclone), here is the breakdown of the car's weight:
1) battery 15oz
2) motor 7oz
3) tires 4.5oz
4) body 4.5oz
5) servo 2oz
6) speed controller + receiver + wire 2.5-3oz
That is 35.5oz, leaving you 17.5oz for the car. Where would you make the car lighter, and by how much. Do you think you could remove 5oz of weight from the rollor (about 30% of its weight)? Everything is already graphite and milled aluminum, where would you take the weight from?
The argument about lipo in a 6 cell shape is invalid -> orion 3200. If you mean the weight, it's silly to add weight to a battery that is only good in making min weight for racing.
The point of going to 4 and 5 cell was to slow the car down and make it lighter, lipo with a slower motor does that even better.
