NTC3 Plus still not shifting
I'm at a loss, I've tried everything to get this thing to shift. I've completely closed both screws and started turning them out a quarter turn all the way to 5 turns out and still no shift.

RE: NTC3 Plus still not shifting
First, a dumb question:
You are changing the correct screws, right? They're the one's at an angle.
If your motor is tuned reasonably well, and you saw no change in top speed from zero turns out to five turns out, and you've disassembled/checked/reassembled the two speed, I'm at a bit of a loss.
Does the second speed bell/spur spin freely on the shaft when not engaged with the pinion? When you have the two-speed assembly in your hand, the second gear spur should spin freely both ways. The first gear spur will spin one way, and engage the shaft the other way due to a one way bearing.
When you have it apart, check how many turns out you can take the screws without them falling out. I can't believe it's not shifting by 5 turns without something else being wrong.

RE: NTC3 Plus still not shifting
Only takes 5 minutes to get it out.
2 screws on the bearing cap. 6 screws on the rear diff case top. You can leave the shocks and tower connected and still pop the top off enough to get the rear drive gear out.
The RTR Plus has the new two speed assembly. You can look at the condition of the shoes, springs, etc. without disassembling the two speed itself.
