Which method to tighten a belt creates less drag.
Tighten the belt tension by moving the motor along the two parallel slots?
Tighten the belt tension by using the idlers?

how much for 2 sets for caliber ii to canada?
Not quite sure about the question, the benefit of idlers is preventing tooth skipping. Both idlers and parallel slots serve as belt tensioning. I suppose if you use the parallel slots arm without the idlers would give the system less drag as oppose to the xconf. arm with the idlers.

Hey marcmt88,

Just want to say huge thanks to @marcmt88 for some custom made motor mounts. I wanted a custom center to center distance that was shorter than what he made before. He said no problem.
The quality is really nice, the vibration finish is a nice touch and the aluminum grade is quite hard! 
Also international shipping only took 7 days to Hong Kong. 
My setup is 97mm wheels, 39t / 20t pulleys, 300mmX15 belt, TB218 trucks with CTC of 72mm. Some people say that this will not work with the idler pulley as head of the bolt will behind or touching the wheel. In my case it works as there is space between the belt and the wheel. 3D printed pulleys. And with TB218’s you have a lot of room to play around.
The only issue I had was with the belts I had on hand I could not get it to work with the idler. I had some smaller bearings #625. 16mm diameter. This allowed it to work with a 300mm belt.
My old motor mounts where hand made by me with a 3D printed clamp. They worked fine but the clamp would crack after some time and it was a huge pain to replace it.

Can 2 6374s be both mounted outside side-by-side using these mounts?
Depends on trucks and thickness of pulleys. I have tb 218mm trucks with enertion 12mm pulleys using these mounts and dual 6374 motors.
How about if used with the GT Evolve trucks + AT setup?
True 6374 motors (not Turnigy 6374s) can fit side-by-side on tb218 and evolve GT.

Correction: sk3 turnigy 6374 would not fit on Evolve GT. TB218 would:

judging by this picture wouldn’t turning be an issue with that deck?
I’m planning out a dual 6374 build and want the motor out the the back and up a little like Evolve’s. using TB 218 trucks. Add me to your list for a set!
Picture just showed dual 6374s can be mounted side-by-side on tb218. The new setup would have a longer arm.

If that’s the case then I’m 100% in for a set for TB trucks!
Hey Mike, I would need to know the wheel size of your setup.
That would be 97mm. Also would you know what belt length I’d need to a rear setup with those idlers?
Hey I’m gonna need another pair for tb218/107mm no idler, short ctc, 63mm motor
