ashalak.... ya the whole name change thing is weird.. they are doing it with all cars.. I think it makes it easier for them..lol the s12-1m pro is the first one that will be put out then they will do the s12-1r for standard trans/motor model... it will have the motor 65mm farter back then the M model. the 104 evo is also known as the s14- something... same with the 1/8 buggies..
keith.. yes the gear diffs are nice for the carpet... I know there will be several options for spur gears on the new buggy... only thing I found was the new slipper got hot and changed the feel on the car... if you take off 1 section of slipper it stays consistent and works great.
