Does this seem right??
I have taken this data from when my CRT had the Neu 1515 2.5D F in it running 5S.

Input data:

Enter Front/Rear Differential Gear Ratio (?):3.30769230 Jammin CRT 43/13

Enter Spur Gear tooth count (?):62 Truggy CRT (Mod 1)
Enter Pinion Gear tooth count (?):16
Enter total battery voltage (?):18.5v
Enter kv rating of brushless motor (?):1700
Enter tire diameter in inches (?):5.65 Crimefighter MTR 1/8 scale truck
Enter the added radius of tire
"ballooning" in inches (?):2 My standard radius is nearly 3. I didn't think this was correct.
Enter Current draw in amps (?):0
Enter motor resistance in Ω (?):0
