A few idea of changes to the 2015 model..
Colour change... White or grey perhaps?
Floating layshaft like yoke?
Floating servo mount similar to serpent?
Option to still run big shocks too so option shock mounts (xray quality not aftermarket)?

the alu chassis works fantastic on very high grip surfaces calming the car, yet making it go deeper and faster through the corner.
But anything less than high grip, the carbon chassis is superior for sure.
The alu chassis is very strong. you would have to hit the car hard enough to break top decks and shock towers before you would damage alu chassis.
It is also a little more narrow than the carbon chassis.
Something I tried for kicks: alu chassis with the top deck completely removed.
Was the easiest yet fastest car I've ever driven! set the lap record within 2 laps and im normally .2-.4 sec slower!
was awesome!
However, I put the carbon chassis back on. I did not feel the belts or car would last long with my far less than perfect driving. the alu chassis was stiff enough without the top deck than belts did not slip after 10mins on track, but I just felt wrong!
food for thought for some!

I have the aluminum chassis not tried it yet, going to get a 1.6mm top deck, split it in the middle, so there is left to right flex, but no front to rear, see how this works, this way I don,t have to be too concerned about the belts slipping

Separately, the Arrowmax aluminum chassis will bend. After 5 race weekends the chassis did lose a flat set.
The Xray Aluminum does feel stiffer than the Arrowmax even though the Arrowmax is wider.

I don't understand why going back to a material that has more disadvantages than carbon fiber. Aluminum will eventually bend while carbon fiber is more durable, lighter, stronger and will return to it's original shape if twisted. Why trying to chase the awesomatix on this aspect. Is not the aluminum chassis that is making this car successful on stock racing. Why do you think real F1 cars chassis are made almost completely from carbon fiber. Just use weave orientation and plies on the fabric to change the stiffness characteristics of the final product.

I understand the purpose of going to aluminum but there's no denying that they are looking at it because awesomatix came out with it first. Anyways, like I said carbon fiber can be made a lot stiffer per square area than aluminum. I used to make my own chassis and shock towers for my Xray t1fk back in the foam tires on carpet days (ply by ply) . The only advantage on aluminum is cost (only if you don't bend one on a crash and replace it with a new one).

Alloy chassis does not really twist like any form of carbon, it's possibly why they made one, cause they wanted to eliminate twisting or reduce it for really high grip, down side is when alloy does twist, it will hold a tweak and you will never get rid of it, does not take all that hard a hit to put tweaks in alloy.

Guys this alu chassis is 40 grams heavier.
It's not just flex.
Being so heavy vs carbon, it changes the handling characteristics.
Not as darty initial, but rolls deeper than carbon and has more forwards momentum through the corner helping to get the speed up.
This is why it really only works properly on very high grip tracks.
The total result of alu vs carbon is a very different feeling car compared to carbon.
Could be just the thing your looking for in a big meet with high traction.
For most of us, it's probably no good as most local races are not grippy enough to take full advantage of the alu!

This can be replicated by simply adding more weight preferably to the front of the car and raising your roll center will make the car act this way. Then try different droop settings starting at 2.5mm front, 2mm rear measured aboved ride height. Aluminum chassis is just another fad. I wouldn't waste my money on it. IMHO
