Unless I missed it... nothing was said about the voltage cutoff. Double check that cause it won't run if that's not set right. (disabled is best for that setup)

Good point GD, I didn't even think of that. I just saw the way he had it wired and what he said the mode was and figured that was it.
If the spur turns as well as the input shaft, I would suspect that the problem is somewhere inside the tranny. Do you still have the shift fork and gear changing dog gear installed? If so, the shift fork may be in the middle of first and second gears. If using a single speed conversion, how are you locking the tranny in second gear? Are you using the steel idler?
The hole is where the shift fork would go. It slides in for second gear, out for first gear, and in the middle for neutral. If it is not held in one position, it can move around taking it in and out of gear.
It looks like you have nothing holding the shift linkage in place like the other guys said, so it's just falling in and out of gear.
If you push it in that will be 2nd gear, and if you pull it out that will be 1st gear.
Obviously if you want to be able to shift gears while driving you'll need another servo.
Yes, 1st gear for acceleration, 2nd gear for top speed.
Second gear should have good enough acceleration though, depending on pinion/spur combo, and assuming thoose motors have at least as much torque as the titans.
Most people only use second gear.
