RE: help wanted
that truck looks to weigh about 20-25lbs. a .25 motor in it is going to suck wind. the losi LST2 is powered by a .28, the tmaxx has a 3.3 version now that is around .21 I believe(this is technically a 1/10th scale, and is if anything overpowered by a .21 engine). and the cen nemesis/genesis, has a .46 motor if your into stump pulling torque.
furthermore, Ive never even heard of the brand(raptor? is that the brand or the truck name?) but I have no clue where you would get replacement parts, let alone hop-ups.
so bottom line, as has been said, no, I wouldnt touch it with a 10 foot pole.
