Either me or my brother have had in the past few years:
Kyosho Readyset rubbish 4wd car
Chadori buggy
HPI sprint (1/10 4WD touring car)
HPI micro RS4 (1/18 4wd touring)
Traxxas Elctric Rustler( 1/10 electric 2wd stadium truck)
HPI RS4 MT (1/10 electric 4WD stadium truck)
Traxxas E-Maxx (1/10 elctric, 2 motor, 2 battery pack 4WD monster truck)
The above have all been sold, deciding what to buy next.
