The reps bringing in the rtr thunder tiger 1/8 leccy tomorrow. It has the plastic chassis which is miles lighter but never going to be as tough as the ali chassis.
RC8 E doesn't have much of a weight difference to the S3. Power and run time are probably the key points in this category and of course they gotta be tough.
Wrca rounds for 1/8 leccy are apparently going to be 12mins
should manage that even with the ali chassis S3
