However, does it require the USB programmer "CC-PHNX-LINK" to enable the brake function?

唔需要,用發射都可以set到,不過0.1v/step cut off就做唔到

cut off電壓由6V起可以按0.1V遞增(e.g. 6.1v / 6.2v.....) :D

:P Dear fellow, I've bought more than 144 piece of magnets today. You guys might obtain them form me and save your effort for finding the sourse. Please don't ask me the price as I treasure friendship more than money. The next step for me is buying the wire for you guys. I shall buy 0.5 and 0.4 in bulk.
Regards, Pong. :P

Pong,

Please reserve 12 magnets for me. If you can find the 0.5mm wire, I need them also. If you don't want to get money back, I can buy you a lunch or a dinner.

:roll: Dear all,
I had away for a while and now knowing you guys in need of magnets. I would bring along sufficinet magnets to flying site (FNS) on Saturday. See you there.
Mak,
This type of motoe has no problem with Li-ploy, provided that your ESC could set to correct cut off level.

Happy winding and gluing.

Dear SHCHAN,

0.5mm wire seems to be too thick for a standard CDROM moter, unless you wish to make a hotliner works in duct fan. I suggest you use 0.4mm. It is very difficult to find magnet wire in HK nowadays. Even you are lucky enough to find a guy who having stock, he would most likely ask you to buy several pound in weight (not in lenght). Regards.

No, it's only a transformer for small electic item. I can't remember what's it for! It convert 240V from the wall socket to 12V power.
