It dosent really matter which model you have they are all basically the same from 2010 on.All I would reccomend to make it bulletproof in order of prefrence are
alloy servo saver
alloy rear diff clamps
alloy rear hinge pin holders
alloy front hinge pin holders
I have run 2 of these ( full fat 2010 for me and a 410R for my 9 year old son, who just won the Irish clubman championship with it
) indoor & outdoor nearly every weekend for the last 18 months.
I have tried the big bores but the car feels better for me on the small bores.
The only parts broken have been the rear shock towers ( but that was going to a new track and landing badly off very big jumps).
