AWS 33 - Brighton 30 October 2010
Moderators: BeligerAnt, petec, administrator
i have a feeling my stuff's gonna be all hasty and last minute again...
Gary: we will be in contact via phone im sure to keep you updated, but it's looking like we're gonna be turning up towards 11, we're booked on the 9 o'clock ferry from freashwater (IOW) to portsmouth, and then from there to the AWS! gonna be tight and i understand it's a inconvieniance but if you can could you possibly move our warm up fight back abit? if it's obvious we're gonna be way late (traffic is a nightmare-especialy now) then just put our opponent through on a bye or knock us out...either way is fine really, the AWS is the most important thing (exept for having fun!) and we should defo be there for that lol

Thanks for the heads-up Jack. I'm sure we can work around it. Hope Arundel and Worthing are kind to you!
Re: charging over-discharged lipos
If charging a "dead" lipo from below 2.5V per cell, you must be VERY careful.
This must be done at a very low current, as the battery is in no fit state to accept a standard charge current.
If you do try to use a standard charge current you will likely cause the lithium metal to "plate out" from its normally safe lithium salt. This is where lithium fires start!
You *do* have a lipo sack to carry this operation out in, right?
And you *do* have a really good charger that understands lipo deep discharge and can safely recharge batteries in this state, right?
Intelligent chargers refuse to charge over-discharged batteries for a reason - it's potentially dangerous!

I dont have a lipo bag, i ordered one like 2 months ago and hasnt turned up .... lol
I will bring the battery with me and see if anyone can recharge it at the event... it was lucky i had one spare battery ! lol
also does a name have to be visable at all times ? i have put the name on the wings that will fold down in battle
also my robot weighs 151 grams.... i am trying to bring it down to 150 but will it still be accepted in abttles being 1 gram over :S ?

Looking over the entry list I can't help but notice that we have a pair of Pants signed up incidentally what's going on there?

Well my ant is ready... but I guess it needs a rethink after the event. It is somewhat disadvantaged in that it can't self right.

as long as your robot weighs under 152g it will be ok
the rules say
Joey;
someone Pete knows that is interested in robots is bringing pants as Pete is away, i think he signed them up then they signed up themselves without realising pete had already signed them up

so as long as it is visible when the wings are down it will be fine2r) Robots must be clearly labeled with their names
