If you took all of the exhaust from every R/C vehicle on the planet I doubt that it would amount to much more than one or two real size vehicles in polution. Yes we all have to do our part to protect this planet, but R/C is such a minuet part of the problem. Tree huggers!!! If they DO NOT have the tree's premission, is that considered RAPE.
Sorry I just had to ask. Seriously do you really think that we would see the end of fosil fuels in our lifetime. No way... Maybe after the next few generations, possibley. The oil barrons are too greedy right now to let that happen, and they have all of the money and the oil to keep it going.
