The Talon ESC doesn't like voltages above about 58.5, it gives a warning. Full charge on 14s is 58.8V so we're only talking about super fresh off the charger. This is at worst a minor annoyance for literally seconds, use 14s or you'll be wishing you had the first time you try it. Just charge the 14s pack fully and use the motor to drain the top 1% off the charge if needed, reset the ESC warning, resume your ride as normal.
I've attached the PDF plates, double check your printer isn't scaling the page or anything, can also actually measure the 211mm as marked to verify. I'm imagining there will be enough demand for a second design that curves the opposite direction to fit around suspension stuff. I'll make that as needed. I'm adding ISCG tabs to the mount also.
Production...about half of the parts are finished for this first batch of 20, about time to start the housings. Each needs about 2 hours of CNC spindle time. Most of the tweaks are small and related to manufacturing difficulty of the feature. The ring gear for instance- the oil channel features are very costly and I actually see not much benefit on the bike, so I had to omit them. Eccentric gears will always have the oil channel but I'll have to get them into the ring gear in a different manner. This is the biggest change to the design for increased production, other examples might be the shape of a pocket is altered a bit to match the cutting tool I want to use. I've made so many variations of this overall design (CAD->CAM->CNC->assemble/test) that I got most of the features right during the CAD portion of the 2nd gen process. In my head I don't design the gearbox anymore but layout CNC operations/tooling. Most of my time is spent making sure bolt holes line up and they're in the right spot, oh shit the ESC is too close to the crank gotta move it, oh shit moving the ESC makes it too difficult to connect the motor gotta move it again, oh shit now I've gotta make both mounts a little longer to fix this, oh shit I'm out of aluminum plate gotta go get more. The the cycle repeats for the next issue.
I'll have the first 5 or so 'upgrade' versions shipping next week I hope; I'll see if I can't talk somebody into posting their impressions since the gearbox half is identical in the new design. Astro is working on the motors and they should be finished in a week or so, about the time I'm ready for them.
Adding some anitfreeze to the water jacket is probably a good idea, it's only 10mL of fluid so you'd only need like, not much. The backpack battery is a pretty sweet failsafe disconnect, like rip cord, just grab and yank. Otherwise I'd say the solid state switch from Luna. Their site says 12gauge wires, I might consider stealing the PCB and soldering my own wires. The CA's throttle scheme I think is more foolproof than some of the Chinese controllers. Increasing voltage is read as increasing throttle and we set a over-voltage limit that indicates a short circuit and disables the CA. The digital throttle signal between the ESC and CA means that line is immune to short circuit causing motor runaway.
