You got my vote for RA2 Wizard. Always and forever.
MUCH better. Still not perfect though.
Make wedges wider.
You could remove the blades if you wanted to, you could get 20kg out of that. What I'd do is switch the weapon and wedge DDT's around, so the wedges are longer without protruding any further from the bot, with the weight distro being further forward, 'cause you'd have the razors further forward as well. And you could widen the wedges with the spare weight as well.
You probably can line your 4WD at the end of the bot. like i did on PitA 8 or FB did on the BBEANS5 champion.Your wedges also would probably be better if closer to the front (plus less weight spent on extender work, and easier self-righting)Oh and to be a nitpick (but good RA2 building IS nitpicking) rebuild the chassis so the front slope is angled 45 degrees and attach the ramplates directly to the chassis, so you save 10 kg.
the angle extenders dont seem necessary, also a lot of chassis size could be shaved for more frontal Armour
