i don't know about the hpi truck but the losi xxxnt is a good beginner truck i race an adam drake 2 and i am very happy with it i started with a xtm nitro xcellerator and it was ok parts were only available online i then bought a used rc10gt and that was a very durable truck and parts were very easy to get i moved up to a adam drake one and with this truck i was faster on the track i have stuck with the losi line of cars ever since then make sure you get something that parts are easy to get that is the main thing no matter what truck or car you get you will break something on it in the beggining when learning how to drive they all break even 1/8th scale cars break
