Buggys are generally the quickest and best handling for messing about on lots of different surfaces. I used to race then abit and something like an old Losi XX would be good fun and pretty sturdy.
I started off in RC cars with a Tamiya Mudblaster- loads of fun but a lot of very easily broken plastic suspension parts (it was a monster truck type thing).
Years later I got a nitro truck – think it was an HPI Rush. That thing was bonkers – it was classed as a stadium truck and it took so much abuse and was rapid. It could do massive drifts as it was rear wheel drive and a mate and I used to launch it off ramps at the local skate park. Hardly ever broke despite stupid things done with it.
If HPI make a similar electric truck these days then I’d go for something like that. I imagine electric motors and batteries have come on a lot since about 15+ years ago so are probably great now. I remember my Losi XX with a 13 double wound electric motor was really quick.
