My FIRST Pan car was a BoLINK invader - took the crappy shocks OFF OF IT, made a Spring front end...resinged the rear end with a makeshift TWEAK system and over a period of 3-4 months had it working WELL on both OVALS and ROAD COURSE tracks...and did a little more modification to the rear pod, using an old ANDY's plastic body mount for a RC10 and put a DIRT WEDGE Body on the car..and tore up some dirt.
(The DIRT body had the rear area where the mounting was kind of unique, so there was basically two pieces of LEXAN pinched together with the body mount holes in them, that were able to FLOAT in the rear of the body so the POD did not bind up and the DIRT OVAL Side Dams actually put the downforce on the TIRES instead of in the middle of the chassis.) THIS THING FLEW on Dirt...at that time (Compared to ANY of the Gear Box type OVAL cars of the late 80s early 90's)
