The slot is wide enough to accept longer pins, so unless you REALLY want the short one, anything that fits is fine.

Ok guys. A little update. I searched PetiteRc for setups on med/low bite and found a mid motor one
http://www.petitrc.com/setup/kyosho/...kaska20121103/

Most people were advising me to stay clear from mid motor, but Im happy to say, this setup transformed the car. I ran it last night, and the rear was like glue, even on brand new tires. Only real changes to his setup was I ran saddle packs.

Going back today to practice, and going to try longer shock ends for more droop. With some worn suburbs, out on the parking lot, the car will do wheelies from a roll, mid motor with split packs! Getting some good traction now. Before, it would just spin out.

I wanted to try the narrow rear, and correct me if Im wrong, but that isn't possible in mid motor? I couldn't figure out which rear hanger would work, so I ran wide.

Got 1st in stock 2wd with my new rb6 Friday, I loved my b4.2 but it was very inconsistent. The rb6 has all the steering and is on rails. Only thing I'm wondering now is what aluminum rear hubs to get. I broke a rear hub my second race but I don't what whether to get the 0.0 or 0.5 hubs, any recommendations?

Looking at Tebo's MM cactus car, would placing the ESC behind the servo and battery back near the motor result in more rear weight bias? As the battery is heavier than the ESC?

Should be. I figure about 50g for an ESC + segment of wire vs 3/4 of a saddle (mine - Intellect 6000s - are 142g a pop) so lets say 100-110g.
