I finally got to ride my Phase 1 dropdown longboard, but in my initial impressions suggested that the skateboard did not carve as well as expected. The board was very stable, but perhaps too stable at the expense of its ability to carve.
When I took off the trucks to remove the remaining pieces of plastic that the board was wrapped in, I decided to rotate the riser pads so that the thick side of the wedge was towards the outside of the front/rear of the skateboard. I did this to reduce the rake on the trucks, increasing the steering angle. If you decide to do this modification, you will also need to rotate the mounting bolts, ensuring that the long bolts are through the thick side of the riser pad.
The result has been exactly what I wanted. The Phase 1 dropdown longboard now drops nicely into turns, meaning that slaloming the dotted white line on the road is once again a joy.
Testing down my average size hills indicates that stability has not been greatly compromised, with no sign of speed wobbles at speeds that would cause significant injury should I come off!
Update 6 April 2008: It appears that eskatestuff are no longer selling these skateboards under the Phase 1 name. Their current boards are branded Vault.
