Castle vs Tacon vs Leopard motor review

Step 1 complete. I received the Tacon today, so did a break down.


Novak, Xerun 4168 2250kv , Tacon, and Castle.
Rotors

Bearings.

The rotors are all roughly the same size, minus the Novak, which does have the longest.
I was surprised to find the 4168 uses the same sized rotor, the closed end is just shorter. But, it uses smaller bearings then the Tacon and Castle motors. The torque to turn the Tacon and the Xerun are similar, where the Castle is much stiffer.

I'm kinda in the middle of tweaking my Pede currently, but as soon as I have a nice full day, I'll do some running of these in my Revo.

I couldn't get a 150amp datalogger, they are back ordered till April. So I have a 100 that is supposed to show up tomorrow. Does anyone know if it would be worth using with these, or if I should just keep it in my smaller vehicles?
