Yep... it's a trainer system, I've got one... It's equivalent to a .46NT I believe, (The .46NT is no longer in production and was weaker than the .46NX) I could be wrong. It's a good motor, just remove the limiters so you can adjust your low and high end better like everyone said.

Also don't believe what the manual says about your motor already being broken in. Break the motor in anyway just to be safe.
