Looks awesome Harry, we need a smashy smashy video I think
The gnomes are my dads. Spurs home and away kits on the pair. I don't think he'd ever speak to me again if I broke one lmao.
I'll try and find something to break. See if how high I can chuck stuff. Wish I could tach it to find out what speed I'm hitting. Probably still loosing like 3-4k.
I'm such an idiot, it took my 10 minutes of racking my brains and rereading that sentence to finally figure it out...Quote:

Hahahah, brilliant :)
Egg comes in at 1420g without a lid. Weight limit fail. That said the plastic version had hit 1600g without back or lid. I can easily claw that 20g back without heavy machinery. Lid will have to be 2mm carbon fibre unless anyone wants to give me a 67 x 235 bit of 1mm. Still got bits of unpockeded alu oozing weight so I should be able to take what I need out of there. Wheel guards will just be folded HDPE for weight and simplicity.
Been hitting some stuff with it today, trying to find weakness. Found lots lol. It tends to knock some of the bearings loose on big hits, this caused the beater to shift to the left and wreck the end of the bearing pocket. Will fix with a file then have to ignore the ugly as no material/inclination to make another bulkhead. Fixing this is easy it just adds precious weight.
Any imaginative ways to remove weight without doing anything stupid?
Thanks.
Try adding a grub screw or two to pin the bearings in place. If that fails get some of the really strong Loctite and have a blowtorch to hand at events in case you need to release them.
I don't particularity want to grubscrew onto bearings... it feels very notgood. I'll just add a plate to the bulkhead to stop it getting thrown outwards on the big hits. With stuff like Elvis's new horizontal I think any adhesives would fail.
Mk3 put the bearings on the inside face lol
Drill n tap the ends of the beater shaft and put a bolt and washer on to squeeze it all together.. will help stiffen up the chassis at the same time.
And yeah grubscrewing onto a bearing is a pretty nooby idea.
Fyi washer OD shouldnt be bigger than the OD of the inner race on the bearing.
Got to be better than nothing at all and having your weapon destroy your own machine. Just giving some optionsQuote:

Cheers for the input on washers. I'll give that a go for now. Yeah next version I should have 12mm thick bulkheads, 10mm to house the bearings and then the 2mm to stop the stupid problem.
Does anyone know when, and where, will be the next opportunity with an arena to fight beetleweights?

Hope to see you there if you can make it :)Quote:

Dave Weston's the best one to ask for that (Razerdave) because he's the one who has the arena!
Going on Dave's advice I machined up some washers for the beater. I'm pretty pleased with the result

Looking good
Welp.

In the end Eggy turned out like this. Not 100% happy with it but I fixed a lot of the problems I've had in the past. Gave up with my radio gear and borrowed a set off Ellis (whattaguy) which meant it at least ran properly.
Event was pretty fun despite lack of robots, I came third out of six (aw yis hella achievement unlocked) which, sad to say is the best I've ever done lol.
Some of the fights

Damage was aight.

Well 2mm cheese was never gonna be much good. Flexed okay and it protected the belts. Lost my bearing retaining washers in the first fight so had to bodge with tape and massive steel ones towards the end.
The 6mm (bit pocketed) fared less well probably due to being a bit stiffer.

Newton punched thru it and killed a gearbox. Warped the whole panel. #rekd
So all in all, not bad but not too good either.
If you are that way inclined you can see a full build of the dang thing here http://bodgeitandhope.blogspot.co.uk...esbeetles.html
Changes for v3
- don't noob the bearing housings
- slower, less powerful motor. The current draw was insane. I'm surprised my lipos didn't died
- shorten the frame a tad, take weight out of stupid places and try and put it into some titanium armour.
- make the electronics, drive especially not suck. Want some wasps ideally. But a new mixer and a new transmitter should keep it together for now.
- more ground clearance
Also planning a horiz spinner using this disc

Its basically Ellis's robot but without the skill, execution or effectiveness. Current name for it is Red Wedding.
Peace y'all.
Replaced the green banebots which are pretty worn down for orange ones. Will keep the greens as a spare.

Also just slapped a hdpe baseplate on to see if it made much difference to clearance. That and the new wheels make such a change. If Alex's arena floor panels are flatter than the other arena then I will be doubly happy.

Borrowed an NTM from Tweedy's new vertical just to see how it would fit on Egg. Looks promising but the 3mm shaft makes me cry. The longer, more powerful (better suited probably) but unfortunately heavier 2836's have a 4mm shaft which would be a direct replacement.
Rethought the wheel guards and rear armour. 2mm ti. I have some real cheesy grade stuff so the bend shouldn't be an issue.
Bolted on the front with a standoff two thirds up supporting it. I could angle but have no real desire to.

Thoughts?
Looks brilliant mate, liking the ti too :)
Awesome haz, build it
