I agree with Tom that two stock FP motors with transmissions are the best bet for you. You might need to follow up with a little different transmission (final gearing) to make up for the fact that you are driving bigger wheels than what the transmission is intended for. The kit battery might getyou around the track but a larger version of the same battery might be a better bet. You can buy new ones but there are various surplus shops around that might have used or surplus devices for sale. You will need to check around in your area. Since this is for charity, a local battery shop or car parts outlet might be willing to lend you or donate a battery of more capacity.
