I suggest putting in a water proof Vilineon Brushless power system and water proof servos, water proof speed control, and Racing tires.
Both have advantages. Gas is typically a faster and more uniform heat, while electric provides a more easily controlled temperature.
Because they would go faster and would be better on carbs
get a gas powered one
nothing is wrong, the fan is controlled by a belt that is powered by the crankshaft and the faster you go the faster it spins
Electric hammers work much like regular hammers, except they hammer much faster. They can be powered by batteries or by electricity.
a gas scooter it will go faster than an electric.
they are faster, louder and can kill a child alot quicker than a duracell powered car
gas is faster and better but costs way more
All you can do is buy a higher powered motor. But if you do this you will need to get metal gears to put in your gearbox as the extra power strips plastic near instantly, and its not fun having nothing to do while you wait for the parts. Also keep it greased up, less friction equals more speed.
only if you need to listen to music for a short amount of time. A hand crank powered boom box, will charge faster than a solar powered one, so you can listen almost instantly. A solar powered one would be better for a long term usage like working outside while painting your house.
all paintball guns run on gas. some have electric triggers so they can shoot faster.
yes
