Mine are running off a 14.8V Lipo and I have a 54-46% weight distribution (front to back about the centre of the wheelbase) according to solidworks.
We have an unknown distribution (lol), 12v drills at 18v and yes, two Electronize 30a ESCs.
We have more weight over the front wheels. It actually benefits control, we steer around the front of the robot whilst the back wheels slide a little. Makes for some pretty interesting drifting!
Are you using the 14.4v models?
Interestingly you 2 have quite similar robots in design but have taken 2 very different approaches to making them.
Ellis, you have taken a more 'Bitza' approach of using existing materials, blood, sweat, tears and hope!
Alex on the other hand has carefully designed in CAD, bought Li-Po's etc...
Apologies if I've got that all wrong! But there's nothing wrong with either approach, be interesting to see how they pit against each other. Personally I'd like to see them turn out quite equal.
As for the Gimson motors I believe they use Drill motors for power the hrs-550s (various voltages), they just have the massive added advantage of Metal gear boxes, supported shafts and decent mounting points.
We have to have a dual now! We can't leave without going Mono'a'Mono! (Is that the right spelling of that?)
don't forget a compination of the two
4wd drill 18v lifter + 4wd gimpson spinner = 4wd 19.2v lifter lol :)
That insane concept did cross my mind for a havey weight robot, have a spinning disc and a lifter on the same side. The arms of the lifter and the two actuators going on either side of the disc, the disc motors below the actuators and have the ESC's and batteries at the sides as per both designs... it would be a mad design, mad build and a mad robot!
And sadly, currently illegal! D:Quote:

The top panels have all been quite rushed. We are leaving for the UK on the 31st, and my dad has a music client in from tomorrow (23rd) to the 27th, so we've really had to push. That plus our original cuts on the plastic (mainly the inner bulkheads) being really quite... lacking, means the panels are all a bit twisted and slightly odd. It looks great in pictures, though!

It weighs 13.1kg. Will probably be about 13.2kg when 100% complete. The drive has dulled quite some, as expected, not majorly though. We're a bit worried about our battery life. We only have 2.6ah, which has been fine until now, but with the added weight we may be pushing our luck for 3 useful drive minutes. We shall see. I think it's quite uncommon for battles to last the full 3 minutes?
Anyway, off to bed! Let me know what you think. :)
Most peoples batteries are capable of doing nearly 2 fights, 2.6ah should be enough but if your using the standard drill cells, then they won't be very good quality, and thats whats letting you down.
Don't worry about it looking uneven, some of the spinners you're up against will soon 're-model' it ;)
As for the cells I'd discharge them and then trickle charge them nice and slowly the night before the event. Then on the morning (at the event) give them a fast charge until they're brimming!
Then after each fight (once they've cooled down, do not charge hot) give them another fast charge.
You get some pretty decent gaps between qualifier fights. They should last fine, plus I'll bring you those spares (they're not made into packs though, so bring some gaffer tape!)
ps. Just looked through the photos, I like the way the armour moves with the lifting mech. Reminds me of a turtle! Pulling it's head in.
Tormenta is looking AMAZING (He or She?)! I looked through the build album watching it develop and it is very well built, by my standards anyway. Is it going to stay that white colour or is it going to get a make over. I deliberately spent a few more pounds to get my parts on Black so I did not have to paint it afterwards but the day we can buy a black chopping board will be an interesting day to say the least.
