any truck you get you will see things that will need atention, all trucks will need to be disassembled and checked for loctite on all the screws, make sure that the servo throws are true etc. but the only trucks compare to the 7.7 are the lst and the mgt. ae has terrible cust support (trust me) and i just got the lst2 so for durability we shall see. i have these trucks, savage x2, lst2, mgt, genesis le, nemesis, excellerator , rusler by traxxas. the only one i dont have is the revo, i just dont like it personally , too small. good luck on your desision i know it will be a tough one. but which ever one you choose there is always next year to buy another.
