360 - mini hypnodisc

[Mouldy]

Well… a lot of people are doing updates thick and fast to there build diarys and flapping that there not ready so i thought id post where im at;

Got bored so took it all apart, re greased the gearbox's- messed about with the brushless motor a bit, and loctited everything and put cable ties around connectors etc;



have a few people comment on how small 720 is… this is how… the electronics are very compact in the back;



I noticed the amount of axe's signed up… decided to make a HDPE lid to go on top of the titanium just incase;

Liked how the pits operation got compared to F1 style this year… i cant change the wheels in 3 seconds, but ive got a decent amount of spares this year… no spare chassis, but i presume john lear will have enough to go around on the day lol…also got a spare tz85 on its way from Aus which Nick kindly said he'd bring for me;

current weight with the stainless wedges and the hdpe lid added is 13.57kg… 30g's to stick some foam in the top over the lipo, then just need to stick it all in the car….don't know how I'm going to fit it all in before next wednesday but ill try my best

How come you have so many spare wedges? They look like the last part that would break...

If the pits have to be run like an F1 race, are we getting F1 grid girls too?

[Eventorizon]

He can change sets to get the drum even closer to the ground and in case they get chewed up my another spinner. Even if its just the leading edge that gets bent then they are useless. And because he can :-P

[Mouldy]

Nah they all started of the same height- although the nylon ones I had fitted last year are worn down and now the drum only has 1mm of ground clearance... I got 2 sets of stainless ones that I'm keeping back to fight wedge bots with, no point blunting them off against robots that don't even have a wedges

Lol

720 didn't have the best luck this year, only really lost fights due to it breaking down which sucked…

the motors kept blowing for a few reasons.. the main one being the weapon has now improved alot… which when i get a big impact puts alot more shock through the robot- causing the lipo mount to flex into the drive motors and knock them out of align… so the lipo box will be going from 2mm rubbish ali upto 5mm T6 for next year…the thunderpower pack also failed causing the low voltage cut out to kick in, meaning next year im going to upgrade to optipower… which also saves weight and space inside the robot.

A new set of drive gearbox's are already half machined- these are basically beefed up Banebots units with rear motor supports (probably not needed- but i want belts and braces for next year) and im going to improve the gears inside to stop the output shafts pulling out.

The titanium drum did the job nicely packing a bigger punch and only suffered minor scuffs… and i couldn't fault the customised motor i made.

Once those issues are sorted out its just down to driving next year hopefully.

couple of clips from when it was running;

I think ~2mm titanium would be better than 5mm aluminium for the battery divider but either way, I would still use those guide screws you had in both the top & bottom panels.

[Mouldy]

The guide screw was just an on the day fix… which proved the plate moving was the issue… i think i will go for 2mm ti next year, combined with a smaller optipower lipo and more padding it should all work out nicely… ill weld a tab going the length of the base plate, and one on the lid to prevent the plate flexing forward… ill also be upgrading the lid to 3mm ti for next year.

Also i came up with an idea that callum has put into process for me to help strengthen the motors up, as it became apparent that the g-forces in the robot could also bend the motor front plates, as their pretty damn weak… he's nocked up some motor enforcement plates for me, and made a few spare sets if anyone is interested in purchasing some to fit the banebot p60's…he'll be selling them for £30 per motor… that includes a custom motor front plate to fit the gearbox, the rear motor retainer and all bolts etc to fit. PM me or him if your interested in a set.

[Ellis]

Those look the deal! Would probably have a good market in the US.

[overkill]

That's excellent work, is it a whole new backplate on the P60? this would be just as useful on smaller motors - I regularly have 540 motors bend or work loose.

[Mouldy]

Yeah it's a totally new back half if the gearbox... don't see why it wouldn't work on a 500 size, the rear support plate might be slightly over sized though...

Forgot to mention the holes are M4... Not the dodgy American imperial size the p60 comes with as stock.

First set provisionally sold looks like these could be popular.

[PJ-27]

What size motors have you got on your P60s Dave?

[Mouldy]

RS775 18v... if anyone knows of a uk stockist of these motors id be glad to know... i recently emailed banebots asking if there still trading with no reply...

[RogueTwoRobots]

I emailed them as well to see if they knew when their 125mm 3/4" hex wheels would be back in stock and haven't had a reply yet either. They were definitely still trading as of February when I ordered my stuff, and were pretty prompt at dispatching it too.

I'm planning on ordering some new 775s when I get paid mid-May. Will give you a shout beforehand if you want to tag any on the order to combine shipping/import costs.

[overkill]

They are totally hopeless at customer service; I have emailed them in the past and they have always been slow to reply or don't reply at all. I wouldn't read too much in to the slow reply.
