ECS-driveshafts (double-jointed) are pretty comon on the Xray, but that is mainly because Xray normal driveshafts are "bad" / give alot of wheel-chatter, and because Xray made some very good ECS-driveshafts, that are durable.
Unfortunately they are too long for the Tamiya, as Xray only makes 50mm and 52mm driveshafts.
