Losi XXX SCT for 2WD or Losi Ten SCTE for 4WD,
guess which brand is my bag!
You wouldn't go wrong with a Blitz or SC10, both very competitive, both strong and easy to set up with lots of aftermarket parts if you desire.
Our club is full of HPI and Associated trucks and couldn't say one is any better than other, just personal choice and driving style i suppose.
the Losi XXX SCT is very similar idea to them so can't see why it wouldn't be as good, just not tried one yet!
If you want 4WD then the Durango is the one to have, seems to be far quicker and balanced than others... if you want 4wd but don't want to spend £280 on a roller then go for the Hong Nor SCRT10, brilliant bit of kit for the money, i use one as a back up truck and club racer, love it!
If going 4WD then note that they sap power so you will need 5000+ LiPo's with a 50c+ rating and a 4.5 550 set up to keep up with us.
The 2wd class is far more popular with a good field of them at most club meetings i've been to lately.
