360 - mini hypnodisc

As a rule of thumb, In-runners are lower voltage and Higher KV and Out-runners are lower KV and Higher Voltage.

In-runners go up to about 8S max voltage where as a Out-runner will take 12S. However, In-runners can go as high as 5000Kv+ where as most Out-runners do 500-1000kv, only 10-20% of the In-runners.

This all of course depends upon their size. Scorpion have a HK-25 that does 3500kv, and a Turnigy 1015 can do 11'500KV. On the other end I have seen a liquid cooled in-runner as low as 620Kv and a Our-runner at a mere 168kv!

This has been Roseanne, your guide to the world of facts.

That's really interesting! I always assumed 720's motor had a much higher power rating as I need a Neu 2210 motor with almost twice the power to get Shiny's eggbeater spinning at the same or lower RPM. That's suggesting that eggbeaters are very inefficient and I might have to change to a drum in the future.

Wouldnt be suprised... wind resistance has a massive effect on continuous current draw.. all the air inside the beater will be wofting around causing a massive amount of drag.

The spinning OD has a large effect on spinup current aswell.. my drum is only 95mm tip to tip and the gear ratio is 3:1... quite high considering the OD of the weapon.

I spent more time deciding on weapon motor/ratio/drum weight when designing 720 than anything else and its worked out really well... the castle motor only gets what id consider luke warm after 3min of abuse, and now its combat hardened i wont be changing them.

Do you reckon a drum with no teeth, just sort of an abrasive surface would do any damage? Like mega course sand paper almost?

[Ellis]

No, not anymore anyway. It'd scuff paint and HDPE but rip/blunt/make lots of noise on anything hard.

not done much in ages…Life got in the way… going to start doing a bit more soon hopefully…

Thanks for Grant for helping me put my ideas into a CAD file that i can send to the laser cutters next week… ive lasered some cardboard templates to see what the hardox version will look like… 722's armour is a bit different to 720's…never really liked the spikes on the side, its not very refined… so spent some time coming up with the new shape which should also help in a few ways…. Card mockup;





Im happy with it, hardox is going to the laser cutters in the next few fays

Goddammit! That's what I was thinking of for armour on Drumroll next year, based on the Aussie drumbot Reboot. Might try it with tube instead, see how that goes.

Totally not copying.

[Mouldy]

whats reboot?

…also… glad you commented first… i put this up specifically so you'd see it and not rip me off haha…if you do… we have proof now

DEAD SEXY! It looks tricky to weld though, will you be making up some jigs or just using lots of clamps?

[Flag Captured]

That looks really awesome! Interested to see how that shape works out in combat. Also be interesting to see how those Colsons work out vs. the Banebots ones, they definitely look a lot grippier to say the least!
