What you might want to try is the Duratrax Cliff Climber, a friend from another forum I convinced him into getting one and now he's hooked on crawling. Uses Clod-Like axles as there are no shafts just a motor on each axle and theres no differential but instead a solid spool. Off towerhobbies.com it is about $120 but then you still need 2 batteries and if you don't already have one, a nice charger. Heres the links to all the stuff. It also has 4WS(4 wheel steer)but after a while my friend locked it out. Also the tires are not beadlocks but they are 2.2 sized with a 12 mm hex.

And then you would need 2 of these:

And here are some choices of good but "cheap" chargers(by cheap I mean in price, may seem like alot on some but they're all good chargers:
Probably the easiest ones of the onyx line to use, just plug and charge(would i recommend them no i'd recommend getting a better one):

This one below is the one I use, charges NiMH, NiCd, Li-Ion, LiPo, LiFe(A123) and has a 10 battery memory! Great charger for the price and the features

And lastly, this one will only do NiMH and NiCd as all the others besides the 230, this one although charges 2 battery packs at a time instead of just one:

Anyway I hope all this helps you because the RTR Scorpion is just too high of a price for what it really is out of the box, plus this one is not too big, not too small but its a great crawler out of the box
