I think having 2 separate buggies is best for this. You have to cut corners and sacrifice to make a convertible car. In the US, it is normally rear motors. even the guys from Europe come here and use rear motor. But SRS decided to make this event more of a mid motor? Why? I dunno, maybe TLR and durango paid them, lol. I am still looking at the Yokomo and might get one to play with for fun. Since the support would be low, I get to try and tune it all by myself, lol. And I consider yokomo to be AE's cousin, so keep it in the family, lol. I actually like driving the 22 and the b4 back to back and comparing them. Need to add a yokomo to the mix.
