i do like the look of the hyper allthough some of the parts look quite thin espially on the suspension arms,as for rc8 it depends on the driver i seen quite a few break a lot but thats really the driver but they also drove it hard as hell to on the track,i was looking at the d8 before i got a losi eight 1.0 but none of the hobby stores where im at had the parts for it dont know why though cause it is a diversion of hpi racing,the eight isnt bad my the way u just have to drive it smooth u can drive it somewhat hard the parts do seem to wear quite quickly though thats the only thing i dont like about it
