Why Electric?

Plus keep in mind just because your power comes from a tiny gas engine you DO still have electronics on you truck. Keep that in mind next time you go through a puddle!
All it would take is for your throttle/brake servo to get dunked without protection and there goes your nitro truck screaming down the street.
One last thing to remember is that electric motors can run in water w/ cleaning, for that matter some guys used to break them in under water, yeah under. Where as w/ nitro engines they will rust and die after just one puddle if you don't clean them.
Run what ya' like but those are the facts vital.
