Going to make some guesses, I assume this is drop center? How is the weight distribution front to back? Looks rather centered. I would suggest avoiding this, there have been many reports of the rock causing unpredictable behavior. Left to right distribution looks ok.

Why on earth did you stay 2d with the electronics? This many ESCs screams to move into 3d space. It will make packaging a collection mechanism (if applicable) much easier and make your electronics guys less likely to kill you. Where are the paths for the wires? You have to have a bundle of 14 10 gage wires from the back of the bot (PD board) to the front (Victors). Trust me, that won't be fun. Suggestions; Remove one of the 884s, space the rest out a bit. Turn the Jags 90 degrees either way, you have a cross bar right next to them which will make servicing them nasty. Also, make mounts for them to sit at a ~30 degree angle with a slight overlap. This will open up a path through the middle of the chassis for the wires to run to the front. Move your on/off switch closer to the back to let wires run where it is now. Running your PWM cables is going to be miserable, get some clearance between anywhere you need to place a cable and any frame members.

Can you tell that I am a wiring/programming guy? :)

Looks nice other than those minor complaints. Very clean render, thank you for not making it grey on a black background. Very crisp and clean, I can actually see everything. :D

As for lightening, I assume that is 1.5x1? Take a .75" bit and pop a hole every 1.5". Probably doesn't look as cool but it is a pretty simple process, you know, a job for a freshman (or a programmer).

First off. Props to you RC. Looks awesome. Takes alot time to do that. Over all, how long did that take you?

Also. Just as a side note incase you use the chassis for a T-Shirt launcher or something. I'm assuming you put all the electronics in there just to show that you can. And trust me. I'm shocked you could! But as Andrew has stated why not go 3d? You have made a wonderful shelf already. Just throw some plexiglass or something similar to your deck on the chassis ontop of it and you could easliy use that. :) Just a thought.

I think he put that many speed controllers in just as a demonstration; They would likely use less during season.

We ran the jaguars in the exact same configuration on a summer prototype with no issue, we only had ~1/2" of clearance from the frame rail.

The Drivetrain, I really have no clue at the moment. I'll go home and open up Solidworks and check the time it has on it. Yep, the electronics are there for show and we have used our "3d" space in the past and we usually build our electronics layout around the robot.

08 and 09.

Yep, the speed controllers are there for demo.

Yep, the centers for the 8wd drive are dropped and the 6wd also. I'll take a look at Solidworks today and see where it says the center is.

I'd split the frame into two configurations; 8WD and 6WD. For season you will make a decision of whether you need 6WD or 8WD, and then it would only take 5 minutes of CAD work to select one. I think having both machined in is a little bit silly, you're adding machine time, weakening the frame rail, and making it a bit uglier. Minor concerns to many, but a bigger deal to others.
