Many of their top US guys (Tebo, Maifield, others) have been testing a 1/8th buggy for several months. Look for it fairly soon. Don't know if by Christmas or not, most likely next spring.
AE have said repeatedly that they will not make a 1/10 electric 4WD. World-wide, the market is so small they're not interested. Small size of the market is shown by the fact Losi is not working on a new 4WD either.
We have a podcast on
www.4wdrc.com with Adam Drake where I asked him directly if Losi is working on a new wheeler, and he said no without any equivocation. I think I'm on good enough terms with Adam that he would have answered the question much differently had they been working on a new car.
