where to connect schottky diode

[Beerman]

Ok, instructions always say to connect to the motor, but I saw a few pics of people mounting them on their ESC wires (between ESC and motor connection).
Is there any advantage/disadvantage to either way (beside buying less of them if you connect on wires).

Those i think are the power capacitors you are talking about, but i could be wrong, which i am pretty sure it is though.

just install teh SD to the motor as the instructions tell you too

Those are capacitors not Shotttky didodes. The schottky's go on the motor.

Guys, some people DO install schottky diodes on their ESC wires. I still think it's better to put them on your motor, though. Silver stripe goes on the positive (+) side.

Nairb, you're right, some people do - I've installed a Schottky diode on my ESC motor wires - basically because it's a pain in the arse to solder them nice and neatly to the motor and still make it easy to get at the screws. And hanging out the back like that they're prone to getting snagged and ripped off.
So Beerman (gotta love that name), the Schottky diode is used primarily to help smooth large high-power spikes during braking (according to my Cyclone's manual). Supposedly they're more effective the closer to the motor they are, because the spikes have less distance to travel. But if you consider we're talking almost light speed (the speed that electricity travels) and the length of the wires from the motor to the ESC (a couple of inches), it doesn't really make a significant difference IMHO. The good thing is that you can have more than one SD in parallel, which does make their spike-dampening more effective. So, as I have done, you can have a diode on your ESC wires, and if you wish you can have one on your motor as well. At least with one on your wires you can put a diode-less motor in without having to worry about finding a diode for it.
Naturally, being a polarised device, the diode cannot be used with reversing speed controllers - as soon as you whack your car into reverse, the diode will head for the great electronic component graveyard in the sky (possibly quite spectacularly too) :)
