I would add a cross-brace (1x1 square tubing, 1/16" wall) to keep the frame strong and square...maybe two. They would also serve as additional mounting points for electronic boards and other devices.

As already suggested, using 1/16" wall tubing for the inner frame members is a good idea, but it may not be readily available in the 1x2 size you've chosen (not saying that it's not out there). In the case where you cannot find the 1/16" wall stuff, 1/8" wall U-channel would be a good option to save weight.
