I've broken a few driveshafts... currently I have some T-Maxx shafts on it. I cut the joint off of a female shaft, cut a male shaft in half, and glued the female piece onto what was left of the male shaft to make an extended female shaft. I then used a regular male shaft to finish the whole thing off. So far they have held together. At full droop I have about a 50 degree angle on the front transmission output - this is the joint that I kept popping out with the stock shafts. At ride height with a battery in it, it's not so bad. I drive the tar out of this thing, it works pretty good. My thread is on page 2, I haven't taken pictures of any of my recent work, but all I have done is stuff to the chassis itself and simplified a few things since I last took photos. There's pics of it in there somewhere with the extended links, MSR11 shocks, and 2.2 tires. It will go through and over anything, as long as it doesn't have to climb so steep that it tips over backwards - hence the tire mounted on back of the roof as a bumper, lol. It still goes kinda steep, though. The articulation is awesome for a non-cantilever setup with vertical shocks mounted on the axle. If I was to mount the shocks angled and on the links, I know I can get 90 degrees out of it, but I really like how it drives right now. The other truck in the photos is a stock SCX-10 with stock T-Maxx shocks.
EDIT -
As you can see, I really, really need to drop the transmission about an inch. I THINK I have a way figured out that won't affect the suspension geometry too much, and I have some aluminum stock ready to go. More importantly, I need steel driveshafts, steel output shafts, and probably some stronger axles. I haven't checked yet, but I think I have started to lose teeth on the rear ring gear. It has a slight tick to it. This thing also has a LOT of miles on it, I used to take it for several miles a day out hiking when I had the time to do that. I'm amazed it's been as reliable as it has been - the STOCK driveshaft made it probably 30 miles of beating on it after I put on the shocks and tires, and it had T-Maxx shocks on it from almost day one, a year and a half ago. I do dumb stuff, too, like letting friends drive it who just want to slam reverse and then forward doing wheelies for a half hour straight.
