RE: Losi XXX-S vs. XXX-S RTR
Losi say's right on their website that the XXX-S RTR uses all of the original XXX-S parts. So it is the exact car with the RTR "Factor" added in. The body and all electronics are included, but you still have to buy a battery and charger.
The one Question you have to ask yourself is, do you need the electronics they supply with the RTR (You may already have the parts and can spend extra money for batteries, charger, extra parts, etc...), or do you want the electrics supplied with the RTR? (Some people want a specific ESC, radio, or reciever for their cars.)
If you already have all the parts you need other than the car, and you were planning to spend that much money for the RTR, then get the XXX-S Graphite Plus over the XXX-S kit. Look at the parts coming on the XXX-S Graphite Plus, a much more worthy car in my opinion.
