just got a nylint scorpion
 

i just got a nylint. i have been out of the whole r/c scene for a few yrs the last trucks i had were and e-max, juggernaut 2 with complete juggular chassis kit, wild dagger, stampede a couple rc10's and an rc10gt. after selling all of them to finance my first 1.1 project i have always missed working on them. i figured the nylints were the perfect was to get back into the hobby.

my question is. what should i do first to help the reliability of these things. i have seen the dif mod post but its more confusing then anything. i dont understand what they actually glued??? i just ordered a "real" radio for it and i plan to intigrate that soon. i was also wondering if there are any motors out there that are more powerful that would fit in place of these.
thanks!
