Mmmm it's starting to sound kinky
Galactus and Boner should be added to the Drum-off mix.
How are the aerial problems?
A bit weird...tried an orange rx with satellite rx behind the wheel (no armour above or below it) and i only get about 5m range.... tried with a genuine spectrum unit that came with my dx7 and thats a bit better with the satellite, i get about 6m range....but its still dodgy as in my plane it goes for 100's of meters without an issue.... ill keep playing about with it until i get it right.
Gonna get this thing going over the next few months;

Oh smeg... does that mean 360 will be at GSL 2013? That would be both awesome and terrifying at the same time!
Probably just for demo's and maybe the odd whiteboard, doubt it would be competitive against some of the new stuff, that and I can't drive 720, diablo and 360 lol
I doubt anyone would be suicidal enough to put their robot in with 360 for a whiteboard... not even me! And which machine will you drive at 2013? 720 I presume.
Tron will do it :mrgreen:
Can always count on you Craig!
And yeah 720 will be in the competition.
Decided to ditch the servo feedback on the arm as its always caused problems... going to have just limit switches feeding back to the H5 now, so there ordered, when there in ill get some videos etc if the H5 still works lol, also means since i lost my disc man (Kenny decided to go build his own robot) ill now be driving it all from one DX8, ditching my DX3R.
Also changing the ratio on the disc to 4.5:1 giving a disc speed down to around 4500krpm, should still be ok, hopefully more reliable.
Also snaped one of the connector blocks of the scorpion XXL, so that's going to be hard wired... just waiting on all the bits to turn up then i can get going.

done a bit more tonight, disc still fits;

limit switches fitted and tested electrically, just need to make a wiper arm to hit the switches now. wont take long;

Nice to see it coming back Dave. Looking good! Just get it into completion !
Glad to see your putting it back together! Never got to see it perform.
Some nice pictures there dave.
What is the disc driven and powered by? Two scorpions of some size [HK-30?] and I am guessing a 10S lipo?
scorpion HK4025-890KV on 6s;
originally it had two 30 size 1400kv motors, never worked reliably.... when it was filmed on gadgetshow it was only running on 1 small 30 size motor on 4s!...

theres a first stage reduction, then down to the angle grinder gears, the grinder pinion is supported both sides, 2 bearings in the gearbox and one at the other end with a bearing mounted into the side of the disc support....

Had an accident with the limit switch setup while finnishing the self righter... which resulted in blowing a track on my H5.... Again.... sorted it now though, patched the track back up... after all the repairs to the PCB over the years... theres not alot of original board left now lol;
http://i685.photobucket.com/albums/v...60D5F421B9.jpg
So with 360's disc at slightly under 5kg, running on a HK4025-890 at 22.2v with a 6S lipo. What is the reduction from the theoretical 19758 RPM?
With Binky its a HK4035-630 on 10S with a 4:1 reduction and the disc weighs 3.5kg... does that sound potent? Our theoretical is 23310RPM to 5800 rpm at the disc.
you'll be fine at that... 360's setup might be going a similar way.... higher voltage = lower current.
So that line in the show about it working perfectly wasn't entirely true :crazy: At least the end of the sentence was right!Quote:

1/4 of the teeth done here... Very boring work;

Just one more to do and I'll be happy :)
Most bored people just sit and play Xbox or something. You go and make some precision brass gears from scratch by hand. Crazy person :shock:
Seriously impressive. Most of us would end up with off-centre gears and wonky teeth if we tried that. Did you just use the plastic ones for reference to get your spacing and such spot on?
Both my xbox remotes are broke :( lol
I'll take a few pictures when i make the 2nd to show how its done :)
Can make me a few pairs if you like :proud:
very nice, good fix for those Bosch plastic gears
A decent shaft for those and your away
Awesome that!
How long did that take!? Very impressive though.
Little guide;
Mount gear and blank on original shaft next to each other and mark out root diameter of teeth;
http://i685.photobucket.com/albums/v...5AF6470D75.jpg
Hacksaw each tooth using original gear as guide down to root marking;
http://i685.photobucket.com/albums/v...5AFFEEA399.jpg
File with a needle file tooth profile again using original gear as guide;
http://i685.photobucket.com/albums/v...5B05D8B6D9.jpg
Repeat until will to live has gone completely, then tidy up with emery cloth.
Time taken about 1.5 hour per gear.
Alan you can pay me if you like :p
very nicely done dave! impressed :)
When repairing a gear many years ago. I found making a tooth profile gauge very helpful. To do this I used some undamaged section of the original gear and pressed hard into the gear teeth some P38 car body filler, let it go hard, and cut off the excess on the sides and then slide off the the remainder, this gave me a guide of the profile for the repair.
Hope this helps.
Craig
Very good Dave.
Dave,
Credit where credit is due, I've done exactly the same thing before, total piss take of my time but worth it, mine weren't as good as that though !!
Jonno.
Thanks guys, hopefully it'll be worth it :)
Just need to make a new link and fit a new esc and 360s back in action (anyone want to sponsor me a brushless esc lol? :rofl: )
Probably a stupid question but how were you using a Castle Creations ESC, 160HV I think, with a brushless motor. The ESC only has 2 outputs and the brushless motor has 3 cables.
Can you use a Phoenix ICE 2 160HV with a Scorpion HK -4035?
It has three outputs:

Although in some of the studio pictures, the white cable blends in with the white background and is difficult to see.
The cable is white! No wonder I can't see it! It also doesn't help that it doesn't seem to be on the PDF... Ok, panic over :-)
LOL fail.
you can use pretty much any non sensored esc with any non sensored brushless motor, brands dont really matter.
I use the ICE 200A in 540 as im only running 6s, will probably be the same for 360,
The data logging capabilities are very useful if your looking into brushless esc's, my top tips would be getting the best branded, highest rated one you can afford, then keep your wires short, put on an aditional capacitor and make sure you take the brake function off, and current limiting on, and with scorpion motors put the timing mode as high.
Any quetions let me know.
We have gone with a 160HV as we are running 10S, and as you know more volts = less amps.
We have plans to fit 2 40mm^2 fans next to it to give it some decent cooling.
We will definitely need some advice come our first spin up and on how to make best use of the data logging, and how to add an extra capacitor, and how to set the brake off etc...
Although it's true that Power = Volts x Current remember that increasing the Voltage will increase the power of the motor (In DC motors Power is quadrupled (as is heat) if you double the Voltage) so Current is also doubled.
With Brushless motors each increase in Voltage increases the motors RPM (The Kv rating) and so does it's power (Power is a indicator of both torque and RPM).
