Just returned from a work trip. A lot of prep work and then a busy schedule during the week. The show is a lot of eye candy and neat attractions but make no mistake, there is a lot of serious business going on here. Though, it is funny to see men in suits and women in dress-skirts playing carnival games and munching on sample cotton candy....Continue Reading

Having gone flying through the air 5-6 feet off the ground and being called back to earth by gravity, I have always been impressed with their suspension design and how much it saves my back. My other cars had suspension but it was more for preservation of the depron airframe and not so much for off roading... although they do pretty good on dirt and grass.

I studied the front suspension of my buddy's sand rail and was also inspired by Leadfeather's Mario Cart and a mod C/F did to one of my GTP cars a while back for light and easy rear suspension. I used the existing planform and parts from my GTP kits and scratch built the 4-link suspension using some 3/16" aluminum tubing, .060 carbon rod, piano wire, Dubro ball links, and some ABS plastic. The actual shock is aluminum tubing with a carbon tube inside with assorted pen springs for rebound. They work fantastic and the geometry is amazing to see in action. The rear suspension is a sudo trailing arm configuration using rubber bands for spring and tension.

The airframe itself is chopped and simplified, while the motor mount was raised to gain a little more ground clearance. I...Continue Reading
