I got one 2nd hand 3 month ago and have raced it every week since, twice a week some weeks....
I have jus got back into the hobby after 22 years away, so i guess the few breakages i have had were normal and expected.
Spares, i would advise..........
front wishbones,
shock mount(front).
front hub/carriers.
and maybe the top and bottom plates for the front in case......
otherwise, the cougar has been pretty reliable and does perform well, when set up right.
I changed to saddles recently and i think it handles better now.....
I prefer 3wd and my sx3, but on sunday, indoors, i did both classes and the cougar was 1 lap faster than the cat? mad, it just seemed to love the track that day. Go figure....
You wont regret getting the cougar, I love it now and will be sticking with shumy as the spares/backup is really, as mentioned before, 2nd to none........... Loads of them about and people will always have what you need and the help..... was tempted to stray away but decided that staying british is a good plan...
Happy Racin!!!
