Hello...

First sorry if this question has been asked before, but......

I am VERY new to speed electrics...I ordered the Schiada and it should arrive very soon.

I am planning to use some 7 cells with this boat.

Anyway...after some researches over the net, I found some infos about break-in the motor.

and it seems that there are 2 methods.

1. dry-method:
running the motor @ 1/3 of its voltage....2 cells..till the batteries are dead (empty)

2.wet-method
running the motor @ 1/3 of its voltage in purified water for 10-15 min
Then cleaning the motor and drying it.
Oiling the brush aso....

here my questions, its a kit motor..probably a 550 class...not sure.

Is it worth break-in the motor?
What method do you prefer?
IF I use the wet-method, can I use WD40 in place of oil?


Again sorry if this question has been asked before and thanks for any advices.

well having nobody who apparently know about it...I just tried!

motor used: Graupner 400 BB

I put the motor into water @ about 3 volts (2 Cells) 15 minutes...water was very dark...I guess it was because of the brushes...then I dried the motor....and last but not least I used WD40...it works!

I've heard it works well, haven't had a chance to try it myself. But, I hope you're not using that 400 motor for the Shiada, it is too small. You need a 540-550 motor on 6-7 cells, or a 700 motor on 12 cells.

the 400 was only used as a test motor...
in the Schiada, I guess its a 500, and I am willing to use 7 cells.

Thanks

Do you need to break in motors?

Yes, but there is a differing opinion of just how, if I was doing it again, I'd try the water method.

What if I dont have 1/3 the volts avaible to me?

Most closed can motors have very hard brushes, that will soften a bit if broken in under water at a low voltage.

Don't overdo it because you'll wear out the brushes faster than normal.

Also let the motor (and the brushes!) dry out thouroughly, before oiling the bearing lightly and using it.

The better contact between brushes and commutor will reduce sparking (interference) and give a longer motor life.
