The real pro of running nitro is the fact you get to know more people.
This is because when you run electric you do not need anyone. Charge battery and run until it is emply. Pick up the car and change battery. No need for anyone to help you out with that.
When running nitro you have to ask someone to hold your car while going up the driverstand and after a few minutes someone has to corect some needle setting or put new feul in your tank.
It is just more of a "doing things together" thing.
And this is what makes things fun and exiting.
Specialy when running races and pitstops are needed. The guy pitting for you is also pulled in to the race fun and exitement.
