well, i sugget your first upgrades are bearings and a metal tranny case with bearings, and maybe the turnbuckle set
with those, your car is pretty much indestructable
its fun, but i am starting to miss xmods(thats why in july, i will be starting a project[its also for the urc summer comp
] and im hoping it will be a big project, not small comestic stuff..)
back on topic,
both the t and dt are fun, but i love the look of the t much more, idk why
but i love the dt rims/tires more.. im a confused person on that.. lol
buts they are super fun to mess around with
for speed, they go around 15ish mph, stock, with bearings
for more speed, you either go brushless, or you get a bb2
somewhere on mtf, there is a conversion table, and the bb2 is equivilent to i think 12000kv(i may be wrong, but im 95% sure im right)
i say, go for it
