Orange Dave
http://img210.imageshack.us/my.php?image=img1028kl6.jpg
Orange dave is the improvement to red dave. It has four wheel drive and has lifting prongs on the front. It was not quite finished at hemel but I have now put the hardox on it.
It has good armour and stood up to little hitter well.
It has suffered from a few issues though. Weapon siezed up and stoped working. Ni-cad packs are a bit rubbish. One of the speed controllers only worked in one direction. Soon to be inproved with new weapon, batts and speedo.

Stats
Name: Orange dave
weight : 10kg
Armour: 3.2 hardox front, 8mm HDPE every where else and 6mm polycarb + hdpe top
Chassis: 8mm hdpe
Drive: 4 x 12v drill motors
Power: 2 x 7.2v 1.8 amp (i know not enough) race packs giving 14.4.v
Control: 2 x 30 amp electronize 40mhz system
Weapon: Lifting prongs powered by a Wind screen wiper motor

I'll take that as a compliment. :)

But any similarity with BB is purely coincedence.

Just did some testing on my new feather spinner, which will be a 13,6 kg version of Katjusha/DBA Evil the one toothed, testing especially the brushless combo i'm powering the disk by.

setup was direct mounted 3 kg 250 mm flywheel on the brushless, 110 amp speedcontroller, and 24v worth of NiMh cells, results are 'funny'

spinup is around 1-1,5 sec, top rpm is around 7000 rpm, so about 7,5 Kj of KE energie :D

SKP (Escape)

Weapon speedcontroller
a Sentilon100A HV 2-12S Speed Controller

Weapon
250 mm 3,5 kg one tooth Hardox disk, direct drive by a custom rebuilt 1,8 Kw nominal brushless motor (motor = disk)
i say nominal cause the nominal amps of the brushless are around 80 amps at 24v, the internal resistance of the motor is just 0.047 Ohm, which means a stall current of 510 Amp or 12,3 Kw of radiant heat.

Battery
a 7 cell 2 parallel A123 batterypack, so 22,4v 4,6 Ah (around 240 amp peak discharge)

Drive
HTI or Speed 700 with a custom 1:16 gearbox, driving 70 mm HDPE wheels, driven by a Robowars IBC.

Frame
Waterjetcut/CNC framerails connected by a 50 mm diameter Carbon Tube (similar construction as Katjusha the 2nd )

Armour
Front armor will be 4 mm Hardox 450, rear armor a blend of Titanium and Carbon/Kevlar in the red/black of DBA.
