got into nitro racing midway threw his year an absolutly loved it. would love to have the car your getting for this years season but i cant leave hobao. If i drive a hobao the spanish team manager does pits for me when his son races which is a godsend as i dont have any friends with any clue about rc cars that arnt already in the race. thats the only downside for me in nitro, you need a pitman an the more he knows about the hobby the better.
Imo go for a cheap normal motor to start, better to drive a slow motor fast than a fast motor slow, as the fast motor wont keep the heat in it if u cant push it like it needs to be.
Get yourself a bag of airfilters, i change mine every heat an change the clutch bell bearings often, i never keep more more than 2 meetings an never have a problem.
Hope you have as much fun as i have an enjoy your new car im jealous
