This reminds me of RoAcH in S3. Potentially a killer design and cool looking.But if you want to make it better:-Don't use redbirds for this (they suck especially for a heavyweight drive). Use HP Z-teks in this case or even 4WD HP Z-tek if you want to make some ramming.-Do some round extender work rather than all these grey connectors, way lighter, there's perhaps 30kg wasted on grey connectors.-Put more weapons on the front of you bot. Again with extender work. You have weight to work with.-This chassis could be lighter.-The battery setup is sufficient. But use a big air tank (warning, this thing is huge) or 2-3 air tanks, because here you haven't got a lot of CO2 to power your weapons.As Inf said, get Starcore. I would recommend the v1.0. (ask Sage for the shock, he went directly from stock to S3) Look at the bots in there, it is decent building and learn from it.
You got my vote for RA2 Wizard. Always and forever.
