I'm a little confused as to what you are gaining with all of the triangular pocketing. Seems that it'd be stronger and lighter to just use thinner tubing. Also, if you're keeping the letters on the front tube, it seems like the material in the inside of the "O", "C", "A", "D", "B", "S", and "R" is not really supported very much at all. You might consider adding additional support beams to support this material.

Is the superstructure frame welded to the drivebase. If so, you might consider separating them and making them bolt together to ease in assembly and allow both to be worked on at the same time.

Your electronics board has an interesting layout. It seems like it might be beneficial to swap the positioning of the Power Distribution Board & the Jaguars to decrease the wire lengths between the board and the Victors. This could be complicated if you plan to use the Jaguars for driving, but its just an idea. It seems like your control subsystem is pretty nice and compact in the corner. I do have to ask why you're laying the battery down flat rather than standing it up. Seems like if it was vertical, you would have a lot more space in that rear compartment. Also, I don't see a relay (it might be hidden) or any solenoids/regulators/etc. Where do you plan on placing these?

Its somewhat concerning that the 2009-2010 Electronics take up the complete footprint of a full-sized drive base with no room to spare, but thats another topic. Nice job on this! Its obvious that you've put a ton of work into this and its very nice.
Thanks Nick,

The whole chassis is 1/16th and there are only two pieces of 1/8th. Which are the inside chassis rails. I was being lazy with the letters, but I will do for sure during season if I put a full rail across.

As for pneumatics, I have no clue. I was just trying to squeeze in as much as possible. It depends on the game, I probably won't need that many Vics. So that may improve space. Also hoping for 973 to market that manifold they had up.

I may look into riveting the top piece of the frame to make ops easier.

Thanks for the suggestions.

Just out of curiosity, what is the purpose of the third motors on the gearboxes?
Third motor was an option for show, i doubt that I will end up using it. But if the game requires me to use CIMS elsewhere. A FP has a spot or if I have to reconfigure motors around. Flexibility is what i was going for.

Great Suggestion, I'll look to improve the location in the future.

Jeff nailed the second layer use on the money and Jeff, I think I fixed that wheel problem, but forgot to re-render it.

Thanks for suggestions, keep them coming.
