Done this myself once with a 10"x33". I say, use regular geometry trucks not RKP (aka longboard) trucks. The one I made, I used some long bolts, 1/2" flat risers with some 1/2" wedged risers with the skinny side facing the middle of the board and Indy 215's. This resulted in basically a low rider board with really wedged regular geometry trucks which will make it super turny. I also had ran some 3DM slalom wheels, 75 mm tall and 74a hardness. Have fun, hope this helps and post pics of it when it's done.

Those were affectionately referred to as "shlongboards" once upon a time...a truncation or portmanteau of "short longboard." They're tons of fun, like surfmurse said, and a cool little platform for experimentation.

One little detail though...as you move the trucks to the kicktails, you're effectively wedging the trucks and altering the geometry, which will make them turn quicker and be less stable. You're creating the situation pictured in the top picture below just by way of moving the trucks:

This can lead to instability (speed wobbs), or getting the kingpin hung up on debris, as the back of the truck is kicked out a little and the hanger won't provide as much protection. That can easily be corrected though, with some wedged risers to counteract the kicktails, by placing the wedges with the fat end facing outward. But, that's just me being a huge fuckin' nerd.

Slap some Indy 169's on that bitch and go nuts!
