So thats where my new 1515 went! Found it!

Looks like I don't have a big enough pinion on hand to keep the center diff up to speed at similar voltages.

Even with an 18t pinion on there its going to be slower than it was with the 3800kv motor.

I was running a 14t, but that was slightly too tall for the MMP/3800kv setup on 3S, it ran somewhat hot.

With the MMM/2200kv setup I installed the largest pinion I had, which was 18t, so its going to end up slower than it was on 3S with the 3800kv motor. However, its going to have quite a bit of torque so I imagine I could gear it up further.

I need to buy a selection of larger pinions to counter the lower KV with increased torque.

I don't think this system will have any problems moving the 10TT along considering its the exact same system that pushes the Jammin CRT Truggy along as well.
