i say just use a bunch of burst cylanders with spikes. 3-7 hits and the other bot's a goner.
I haven't done it myself, but here's how I'd make Disector's clawsUse 3 of the Beetlebros' Chicken motors (The serov-typs, of course), and attatch an extender to each one using a side connection point. To each one of those, attatch a Sir Killalot claw.
Clamps doesn't work well in RA2. Especially servos. The only solution I know and used to make a clamp is the inverted side hammer...That is, build a side hammer with a lot of power into it's weapons (like Street Sweeper), but invert the movement start and movement end positions. That is, the bursts' movement will start at the front of your bot and end at the sides of your bot.When a bot charges you, fire the hammers. The two "pincers" will open, the enemy bot will go right between then, and the two pincers will retract and clamp the other bot.EDIT: NO PIGLETS FOR DRIVE! Also, just use 2WD with the most powerful motors and gripper wheels you can use with your weight rather than 4WD with weaker motors. DSL 4WD is like stock, it's best to use it when you REALLY want speed on heavyweights. A MW can be lightning fast with NPC fast drive and techno destructo wheels, and an E-tek drive with techno destructo wheels makes for a really fast drive for a HW too.
there's something like that in Robot Wars: Arenas of Destruction. it's called a hydraulic piercing arm. its quite interesting.
Actually, my trick is to always press 1mm armor first (something with the weight) and just move up thelist in the armor type until you get to the one you want.
Offtopic, but your avatar is really annoying, Hydro. I had to adblock it.
