Clone Motor Mod

Since I was reading alot of post about how fast clone motors were and I torn into my clone before I had a chance to find out.

I decided to mod it to work in my MS and my zip.
The diffrence in motors is how they connect to the power (clone motors are hard wired). I first striped the insulation totally off the ground wire and used my soldering iron to melt a small portion of rear motor plastic to expose a small section of the motor can. Kinda like a slot. Then layed the strands of the ground wire into the slot and droped a small bead of solder into the slot, also soldered a small part of the excess strands of the ground wire to the motor can itself (this was to prevent the solder from breaking free from the slot during handling). Then with a scrap of Plastic (from another project) I melted a bit to the tip of the soldering iron and placed it into the slot to cover the solder. Once this was done I clipped the remaining strands of the ground wire from the can leaving the wires soldered to the motor can intact. Next I layed the positive (red) wire over the rear of the motor and cut it so the wire went all the way across the rear of the motor. Look at a bit or zip motor and the positive wire and position should be similar in appearanceto those motors contacts. Then remove a little of the insulation from the positive wire and just tin the wire (DO NOT SOLDER TO THE MOTOR) and there it is a removable bit motor. This was a first attempt was a little crude only because I wanted to see if it could be done. So when I get another clone I will refine my methods and post a cleaner better way of doing it.
In the meantime, If any one else attempts this please post YOUR methods and results. Oh, on a side note the clones seem to be 2.2's with more advanced timing. This would explain some of the reason they are so fast. (Those who run of have run bigger electric R/C cars will know what I'm talking about.

Sounds like a good plan. My only question is what do you mean by timing?? I can only imagine that you could mean that the brushes make contact closer to the edge of the magnetic field??

Sorry for the crappy explanation, I know what I'm thinking, but I cant put it into words.

It's actully how the motor can is adjusted in relation to the N/S poles of the magnets. On the 1/10th scale motor timing can actully be adjusted by looseing a set screw and rotating the motor can. In some cases you can actully adjust too far and reverse becomes non existant. But with the right adjustment, oh boy! I have toyed with the idea of adjusting the zip motors however the cans are non-adjustable and I don't have enough motors to try. However with my next clone (PBC and parts harvest) I intend to destroy a motor to unlock the secrets (so to speak and devise a way to adjust.

Has anyone ever tried to lighten one of the motors? as in shave off a little of the plates inside (not sure of the technical terms here). I know it would have to be done without killing off the electrical conductivity but the end result would be a vastly more top ended motor.

I would tihk you would also lose alot of torque by shaving the motor. Remember, the inside of the motor acts as a flywheel of sorts, keeping the car moving over various bumps and debris. I would think if you shaved the motor, the car would slow down over even the smallest bumps.

Mattydiah,

I'd have to agree with you the toqure would be lost and besides the motor weight is not that much to be concerned with.
