Default Schottky Diode Soldering

Hello All,
I am a little tired of the tricky soldering needed to Install my capacitors, motor wires schottky diode etc to my motor. What I would like to know is could I solder the Schottky diode between the positive and negative motor wires above where they solder to the motor?? Does any one solder the schottky anywhere other than to the tabs on the motor??

i would reccomend sticking to the normal way
because think about it there is going to be a blockagge in the line of current flow and the diode would probably ristrict flow and have no affect at all because the current drawen to the motor wants to go to the brushes then com the brush and wire again but the diode has no affect during this time

i think

good luk if that made sense

I have heard or read somewhere that some people have been known to solder the schottky between the motor wires up from where they solder to the motor..I just wondered if anyone out there has tried this and to what effect.
It is just a pain trying to get the schottky and motor wires soldered on without one or the other sliding off before the solder has set..

hey steevo

as long as the diode is between the positive and negtive somewhere along the line there is no problem. It can be anywhere from the contacts on the speedy to the tabs on the motor, just that when you do it on the motor, its only one pont where the wires are bear. If you do it along the wires then you have a naked piece of wire hanging around, if you protect that then there shouldn't be any problem.

good luck

You can solder the schottky along the wires - but it has less of an effect (because the wire ends up soaking up some of the reverse current that the schottky is supposed to be blocking)

Just wondering if I can solder the diode near the esc, like a capictor. I know it's best to place it as close to the motor as possible. But if I can solder near the esc then I can save time and money when changing new motor.

i have been soldering mine to the tabs on the bottom of the motor so I can just leave it on when I take the wire off.

Spend the money and install a Shottky diode on each motor. Bend the little tabs up and solder it on to the side opposite the lead wires like in the photo below. The tabs help to hold it while soldering and keeps it tucked out of the way. This works well on a Losi XXXS and a TC3 with the diode on the bottom side. It keeps the diode out of the way and in the position that it works the best, on the motor.

steevo:

i've seen it done before, i haven't done it myself, however, i agree with what people are saying about the closer to the motor the better it will work, so if u have an old esc to try it out on maybe, good luck though

Or you could put the skotty diode between the wires near the motor then place a drop of solder on the ends that stick out so it won't slide off,but the solder on the motor will hold in place.Plus I grab the sckotty diode with pliers when taking wires off the motor.

Thanks for all the advice. I think I will just stick to the suggested method and solder directly on to the motor tabs. Its not so bad on my D5 Flatliner because the capacitors are pre installed so you only have to worry about the schottky and motor wires...
