Hi Bob
We are slowing expanding the on-line data on our range of motors etc but still have some way to go.
The 941D has a 3mm diameter by a little over 7mm long shaft. Weight is between 37g for the 4:1 to 50g for the 1014:1
The 944D has a 4mm diameter by a little over 8mm long shaft. Weight is between 52g for the 4:1 to 70g for the 231:1
Regards
Paul |

Hello Matthew,
The GM12a has a 3mm dia shaft with a flat on it. The shaft is 3.5mm long and as to whether the 4611-023 wheels fit, well yes but the holes are 1/8" which means they are a little over sized. We describe using a brass tube spacer to act as a sleeve which we would still recommend. |

Thanks Very much =D
one more thing, do you have a drawing/dimensions of the brass plate mounting holes? I am designing a pole climbing robot and getting the chassis rapid prototyped, so if i can 'insert' the bolt holes into the CAD drawing that would be great.
Thanks

Matthew,
Sorry but no CAD drawing of the brass plate, I could go and measure it but I would hate to get it wrong and it not fit. If you are happy to take the risk, I will measure it to the best we can. |

if you could measure it, that would be great. I am sure that will be fine.
Thanks ever so much

Apologies Matthew,
I meant to measure the motor today but forgot. I will try to remember again on Monday. |

Hi
A couple of questions; could you tell me a) the width of the 'GM14a - 298:1 Mini Metal Gear Motor' body, and b) the distance between & diameter of the mounting holes?
Thanks
Tom |

Hello Tom,
Sorry for the delay in responding. The GM14a has a body size of 10 x 12mm with an overall length of 31mm including shaft and solder tags.
The mounting holes are tapped and we are not sure of the exact size but could be M1.7x0.35 (certainly smaller than M2). Distance between fixing holes is 9mm.
The above sizes also apply to the GM11, GM11A (O/A Length 34mm), GM12A & GM13A. |

Hi
Can you tell me the weight of the 918d spur gear motor? I am making an ant weight robot and am using http://www.robotcombat.com/marketplace_ant_esc.html for the speed controller. Do you think they are suited? Also I am unsure about the gears you offer...I want the robot to be fast but pushing power is the main thing I am looking for. I am going to use a 7.2v li-poly battery. |

Adam,
Weights of most of our products are shown under the add to basket icon. These motors are some 72g making them far too large for an Antweight. You could make a very good antweight out of our Solarbotics range, the GM18 has been used to great effect with some users using 4 motors in an Antweight giving speed and pushing power. |

Hi
I'm looking into using the 918D and I'm trying to CAD up a model based on the 4mm output shaft gearboxes. How do the dimensions differ from the technical drawing for the 918D with 2mm output shaft? Is it simply a different diameter shaft?

Yes it is as far as we can tell and can see no practical reason why it should differ. You are welcome to post your CAD model here on the forum if you wish as other users may well appreciate it. |
