looking nice but very tight on space. whats the over all dimensions? im also interested to see what you will do with the wheels to protect them once its finished. lol i know you feel like giving up but just think- no self-righting hoops:)
how heavy is it so far ?
and thanks gary for the link ill get some of that
DERUBOLL IS LOOGNKI GOD WARGHG
GO PENGUNIS
Well a night's sleep works wonders for the perspective; I'm not quite so annoyed with it now and reckon I can cope with the challenge of getting it fitted/wired up in such a small space :)
And yes Calum, remembering that I wouldn't need self-righting hoops helped :P
Current weight as it is in the picture is 4.6kg; when I add the drum and shaft onto that it takes it up to 9.1kg - then add another 500g for a battery pack gives me 4kg free for armour! :twisted:
More when the brushless is fitted
Wheel protection will either consist of some 12mm polypro, or 12mm HDPE, or possibly some bent steel/welded ti. Other option is to look at Hornet, which has been running five events without wheel protection and has never lost a wheel. Kaizer's wheels were exposed though for a couple of battles at the UK champs and took some damage but still not enough to rip them off the drill shafts. But they'll be one of the last things I'll consider.
Kody, go on, have another :rofl:
Make that 6 events for hornet so far! :P
Having your wheels exposed with a spinner is quite a good idea as people always focus on them and never think to worry about the big spinning mass in the front :)
You'll be gaining more weight if you go to A123s too mind! Might as well just make it into a hardox box with the spare weight.
I've been considering swapping the poly for hardox actually since the spare weight is there for it. I'll wait and see what the weight of it is all in when its completed; this chassis will probably run at the tag champs though and then I'll look at possibly making it hardox

I still make it five events :lol:
When else has Hornet been out to play?
(yes I sadly have a memory that seems to subconciously note unnecessary robot stats such as this)
meh there was another one in there somewhere. Every battery pack thats gone in the robot so far has lasted the grand sum of 2 events, throw 3 batteries in, you get 6 events :P
Either way my wallet and bank balance have felt the number heavily. I doubt there is another feather out there that has actually required a full rebuild to the same degree after each event :uhoh:
Hehe fair enough :)
Yeah like you said one time, you should really be on Hornet 6 or Hornet 7 by now :lol:
Probably the machine that's had the most TLC in the featherweights!
Update
Nothing major, but will be swapping the polypro that I'm using for the base panel right now for some aluminium, since its easier to bend and mount at the points where the chassis blukhead slopes. I searched on eBay for some ali and the very first item that came up was the perfect width and only requires 20mm trimmed off the length :)
If I'm not wrist deep and sweating trying to fix hornet its usually been retired from the event :P
Gotta love ebay! :)
Well this build thread has been stupidly quiet for a while. Sadly not got any robot build progress to report but I was bored today and trawled through a bunch of old robot pictures and footage on my computer. Came across this from four years ago; ah the good old days of windscreen wiper motors, SLAs and microswitches :)

Exams finish next Tuesday so after that I'll be able to get back to robot work and start preparing everything for the tag champs. Drumroll II is on hold construction-wise at the moment due to me not being happy with the chassis construction and design, so the original Drumroll will be in action again. To-do list includes; making a new cross-bulkhead to replace the cracked one, soldering up some new battery packs out of existing pile of Nimh cells, fitting the brushless motor and controller, painting the drum and (all being well weight-wise) incorporating a srimech arm in a bid to get rid of the ghastly roll-hoops.
Then there's Incisor to build from scratch (CAD started today) and a power tool drag racer to make and pimp, as well as sorting out all the stuff for camping. And by the time I get back home, I'll have a grand total of two weeks - eeep!!!
I'm looking forward to seeing how I get on with this actually. I was planning on having nice new A123s in Drumroll and a well-constructed Incisor etc but the Subway shop I was working in has recently shut down therefore my plan of working lots of extra shifts to raise bot capital has fallen flat on its face. Factoring in camping supply costs and fuel, its not possible to get A123s, appropriate charging gear and loads of bits I don't really need. So modifications to Drumroll and construction of Incisor will involve a fair bit of old-school style 'make do with what's at hand/what can be salvaged from other people's trash'. It'll involve a bit of bodging which means some materials and parts won't be top notch but I'm really quite looking forward to seeing what I can do by returning to the 'use stuff I've already got' approach rather than the 'new stuff bought off internet' process that I've been using for the past two years.
I think I'm starting to slip into 3.30am waddling mode so I'll retreat to bed now
