Oh this will spin it up in like two seconds haha

I have used the Pylon in my Beetleweight Mercury in testing and the Helistar in my Featherweight Overdrive- they both accelerate to max speed in a second or two (Overdrive got to a 13,000 theoretical in ~2.5 seconds or so with a 2.2kg drum) so you could easily get away with smaller motors I suppose... Just got to consider the startup torque so they don't cog too badly haha

How big would the weight be, diameter wise? I have an absolute ton of NTM 28-30s I could do a bit of testing on/ send some across if they'd be handy along with appropriate speed control? Still owe you one for all those offcuts from Manchester last year haha!
