With the 2 losi's I've had experience with, the MRC has good electronics, and the Micro-Baja.....well.....it sucks cheeks. I will not buy another Losi for high speed purposes. But I will continue to buy their crawlers. I would like to get a Propulse, and go crazy on it. I think your problem with the Losi Baja is that, it's a Losi Baja...
But nice little collection you got there.
