i run my t2, the only real issues ive had are the rear arm mounts and rear bulkhead,
you can use the rc10 re-release arm holders in a pinch, but they do snap where they screw in, if you can find them, the rpm 3 deg rear mounts are bomb proof...but there gonna cost you... and the rear bulkhead, if you dont use a ballstud that threads all the way through, the "ball" can snap and you'll never get the threads out, i swapped to captured rod ends and screws, havent had an issue since..
other than that, for me, its an awesome "vintage" truck to goof with at the track, because it shares nearly all parts with a rc10gt, so getting ball diff/drivetrain stuff is still easy... i run a b4 topshaft and slipper, truck has held together great, lots of fun, super simple layout, not much adjustments, just throw it down and drive it "as is" fun...
