I haven't had a chance to put the car through thorough testing yet as it's been raining here since I finished it. I did test the chassis with the solar cell proped on top before finishing the body though. These initial tests are inconclusive as the cell kept falling off and drug around by the car and was often not at the optimum angle to the sun to keep the cap charged. But, acceleration and torque were unreal. This is mainly due to the higher voltage. This solar cell on a stock bit would be similar to a three cell mod since the stock bits came with a 50mA battery. My only concern is that the low current may not be enough to keep the cap full and run the car continuously. If I let the car sit in the sun for a couple minutes, the cap would fill up and the car would fly, but the cap depleted in just a few seconds. But, as I said, the sun was not at it's brightest as it was around 4:30 in the afternoon and the solar cell was often upside down being drug along behind the car. I'll post more accurate details as soon as the sun comes back out. These light flexible cells come in many varieties, so it's possible to come up with many variations on this theme. Your suggestion is sound however. I've seen your write ups on motor specs and have used them more than once. If the mA rating does prove to be a problem, I'll try your suggestions. Stay tuned for more info.
