RE: REvoS
I don't think there is an RC monster truck ( any RC vehicle really) made that does not have model specific "issues".
I've lost track of the number of times i've read "X truck is a great truck as long as you fix A, B and C".
Savage, Revo, T-Maxx, LST, MGT, Warhead, etc all have stuff that could be better out of the box. Admittedly, some are better than others but every single one has it's own special problems.
