Not sure why it's based on the Evo IV & not the V, has it been in development that long? Will it make it to production and if so when, I've steered clear of the 501X as I prefer shaft drive.
Ran a Predator XRS, now on a Cyclone D4 whilst waiting for the Aero A One but it would be nice to have a Tamiya off roader to go with our TB Evo 5 touring cars.
