They're small and simple but I kinda like them. They're cute. How tf are they so heavy though???
I can see several areas for improvement, especially since you have 60kg left over. In order of priority:Cover up those flatmotors, they don't look very IRL right now.Upgrade that polycarb top panel to something stronger, otherwise you're going to get disemboweled by every axe/hammer in existence.Remove the second wheel on each motor, and upgrade the motors to NPCs (Fasts, if you can). You should have the room to do so.Replace all those ant batteries with two red motors. Again, you have more than enough room, and it'll save you a few extra kg.
Ive updated Aggressive Retsuko. [ Quoting of attachment images from other messages is not allowed ] Now being a cruiserweight, she weighs in at 542KGs. Drive motors are 2 NPC Fasts, the weapon is a Mechavore disc powered by a flatmotor ( ). I really like how it came it out, its performance might be sluggish, but its better than the original for sure.
Maybe make two discs powered by two flatmotors.
