I'm planning on buying a new buggy and actually start racing. I was thinking about the Kanai2 or the Hyper7 pbs, and I obviously can't decide between the two. I was also considering the Ultra MBX pro RTR or the Mp 7.5 (and later on convert it into a kanai2, since I'm short in money). Could any tell me which one (k2 and h7) or tell me what I should get between the Ultra MBX or the Mp7.5 and if these two are capable of racing.
