"Your name: matt
Electric kit referenced:fact team tc4 belt
Comments:1. when can we get up close reviews and pics of the prototype belt driven car ran at the reedy race....2. I'm a firm believer faster is better, with that in mind i hope the internal ratio is lower than our all so favorite 2.5
Good question Matt. Being that the vehicle is an early prototype we may not see any info on the car for quite some time as specs will change a lot during its development."
"Your name: ben
Electric kit referenced: none
Comments: rumors I'm hearing that a new generation b5/t5 may be coming out with the release of the rc10gt2...that true? it seems too soon and a waste since i barely just got my b4
