RE: need some advice
The PBS is one of the best starter kit RTRs out there,even though it's pushing 4 years now. But it does come with everything you need to go racing. But there are other RTR's that are a little more reliable in different areas, but not really better overall.
Bu to answer your Q, the Inferno Sports range is the very worst from the most overpriced range. If you can send it back untouched then I would suggest you do before that POS scars you away from the hobby.
