I have a modded 5b that I have uprgraded over the past 5 years and absolutely love bashing it at the park and beach it screams. It is very durable it will violently cartwheel and just keep going however, the losi 5ive will clean its clock at a race track because of the 4 wheel drive just check out youtube and you can find some vids with the two going head to head and there is no comparison the 5ive will be my next purchase but will never get rid of my 5b
