Also, if you want you could combine the two siderails into one part by making a top hat shape. We do something similar in our drivetrains and appreciate the rigidity that closing the top gives us over having two rails.

Everything is 3/32 thick 5052 sheet metal.
SMC-103 is chassis part from the MVRT115 2015 offseason.
JBX-103 is a gear box from the MVRT115 2015 offseason.
I am using CIM motors.
Gear box is supported by the screws and mounting holes.

I am using #25 chain with an 11.5 inch center to center distance. It is a live axle. There are also no tensioner.

The wheel I am using are AndyMark 4in performance wheels. Yes the center is directly driven.
The center drop is about 0.09.
The speed at which this goes is about 17.9ft/s free speed.

Thank you for a great idea of attaching the side rails together. I will try it out next time.
