Well here is my first of two terrors

Name: KE (Kinetic Energy)
Motivation: 2WD
Speed: 14MPH
Weight: 12kg
Height: 90mm
Length: 480mm
Width: 420mm
Weapon: The weapon is an undercutting 300mm diameter 1.6kg flywheel powered by two OS .30 Rotary 49-PI Wankel Nitro motors @ 3000rpm. Each motor has a peak performance of 1.27BHP at 17000rpm and the relative information can be found here: http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXBY72&P=MLhttp://www2.towerhobbies.com/cgi-bin...&I=LXBY72&P=ML
The motors have a centrifugal clutch and starter motor added on to prevent any mysterious stalls. The blade sits 0-15mm (Adjustable) from the floor and is designed to go under an opponent and take out the wheels/tracks/legs. The weapon can be raised slightly to the full 15mm where it can then target the opponents armor or skirting. The flywheel is made out of 4mm Hardox 400 for durability.
Drive: 2 x 12v Dewalts running on 14.8v current limited to 80amps each.
Batteries: 1 x 14.8v 6000N Polyquest LiPoly Pack. Ultra Light, Ultra powerful. Has a continous rating of 90amps and peaks of 180amps. Information here: http://robotcombat.com/marketplace_lipoly-pq.htmlhttp://robotcombat.com/marketplace_lipoly-pq.html
Armor: Combination of the following, 3.25mm Hardox rear wedge & wheel guards, 3mm Polycarbonate with 1mm Stainless steel bonded together for the rest. Uses a very light 15mm x 15mm x 2mm box section chassis.
Notes: A miniature version of Mad Dog (http://buildersdb.com/botpics/719.jpghttp://buildersdb.com/botpics/719.jpg) and is invertible. Extremely deadly! Approach with FEAR!!!

mDU will be posted up later once I research the necessary components and finish the idea off.
