Hey man just read this thread, Wicked build!
Choosing to go RC on a Downhill bike was a very brave move but at least you reap the benefits or mass centralisation. My Giant DH with a HT35 hub feels really heavy and weird with all the weight in the back wheel. hopefully once I've got my full pack on the frame it should bring back the balance a little but I'm sure it won’t be anywhere near as good as yours for jumping and the like.
I second what you say about the throttle controlling speed not power, I've had a few friends throw themselves off the back of the bike because they’re not expecting nothing nothing nothing... Max power. Ideally I'd like the throttle to control the ampage and regen so It could simulate engine braking when you close the throttle.
I like the temp monitors where did you get them?
Hey man, thanks!
Temp gauges were from eBay. Try and get them from a local seller to avoid greenhouse emissions unnecessarily, they sell these everywhere.
They run on +5V, backlit, and have waterproof gauges which go to 100'C.
Perfect! (and £5.50 now)http://www.ebay.co.uk/itm/ws/eBayISAPI.dll?ViewItem&item=230707700076&ssPageName=ADME:L:OU:GB:1123
Oh, and I just installed the temp gauge with some silicon 250'C sealant on the motor windings. Wasn't as hard as I'd thought.
I had to drill a hole in the 3220 (!) and add a waterproofing grommet, so had a few practice runs on spare aluminium before going for it.
I set up a vaccuum cleaner on the drill bit, and some sticky tape on the stator magnets, pointing backwards, to catch any flying pieces of metal before they got sucked onto the stator.
This 3220 is so small! I'm shocked by the power of the magnets though, they're nuts.

- as some people have had shorted end terminations, I checked this - it was fine. Thankfully!
