Another update... I have been runnung the car some on 6S, just have the batteries ziptied down for the time being. I had to make a pair of chassis braces with some spare turnbuckles and a second CD top plate. (Pic to follow)
I found that the 1518/6S combo is way hard on tires (blew my new tires to pieces, shredded one spare, and I'm on the bald OEM ofna's as a last resort now...) so I've enabled torque control and lightened up on the throttle. Looks like I'm setting some $$ aside for a set of OFNA on road belted tredded tires and a set of dirts I'll have to tape myself.
I got a PM from Mike friday and it seems the universal mount will become available this next week, I went ahead and ordered the Mamba XL from castle as Mike doesn't have an arival date yet, so I can start running my matched 4S packs. Currently using a new 4S turnigy with an OLD max crap 2S in series to get 6S. It's a bad combo the MA pack runs hotter than the turnigy and drains much faster so I've got to limit drive time as the MMM LVC doesn't know if one pack is lower than the other...
I also opened up the spider CD and packed it with grease to help the front tires not unload so agressivley. The 1518 was turning them to pizza the moment they come off the ground. I also have to be good about backing off the throttle a bit to let the front contact the ground enough to turn :-) I'm loving it
