Thunder Cat/Zap cat racing

[TIPS 2]

hi there i did search the forum but couldnt find quite what i was after, i appolgise if i have bought up old info.

I am looking a buying a second hand zap cat or ceaser/aquarius. I understand the difference between the championships but was wondering if a four/five old boat could ever be competitive against racing the newer rigs in the champs

Also wanted to know people experiences within each championship is there one better than the other, in terms of speed, sponsorship, media coverage and FUN!!!!

THank you all advice greatly apprecitated
