We have brushed boat (nothing great), and I used to fly a gas Hirobo Heli and used to have a brushed R/C car.
This is the first time I have worked with anything brushless.
Having flown and crashed the heli I am no stranger to replacing parts :-)
My son loves small R/C trucks and the boat so I am hoping he will get into playing with and working on the Stampede. I'm looking forward to running and working on it with him.
