I recently got two of these for my kids. The monster truck design (Quantum Flux MT) is better than the truggy design (Quantum Flux XT), particularly the setup and tyres...although in essence they are pretty much the same car. There is no problem running with 3s although it's pretty quick and is a handful to control...the transmitter/receiver has excellent range though.
We're all pretty much novices and are learning when it comes to jumps and bashing etc, but both the Maverick's outlasted my brand new Arrma Big Rock last weekend (retired with broken rear suspension) even though the kids had subjected their Quantums to much more abuse.
There is quite a few good reviews online and for the price I would definitely recommend them, the only thing from stock I'm going to change is the shock oil to something with less resistance.
Hope that helps.
