lol jamie, im persuming they are fine as i've got them and so has kenny and tom- with slightly different gearing, i've tried one on a battery with the wheel on, and one alone seems to have decent enough power

if everyone buys these motors and they end up being usless- although im sure they wont, please dont chase me with pitch forks

Lol, I'm having to rethink my six-motors strategy as at £12 a pop that's £72 for drive motors alone! Think I might try and rustle something up with speed-hacked servos in a 4WD formation, kinda like Alan's FW Omega, but with a lifting arm like Trisector.

Wait, what am I saying?! I'm a Scot, therefore it should be spinner or nothing!

I am looking to use the 100:1 mini MFA motors as sold in Maplins, and used on my ant arena pit mech, and according to the web, they are 72g, so

I was thinking cheap cordless screwdrivers as motors, gearboxes and possibly a source of batteries (I think the second cheapest from B&Q weigh ~260g) so hopefully with some careful case removal and mounting that will go down.

These work quite well, have a metal spur gear box and are cheap as chips. Speed is respectable on an 11.1V lipo but could do with a bit more oomph!! so a higher voltage would be good. Run time on a 300mAh lipo is half an hour or more.

Cheap cordless screwdrivers are good. I built a 2 lb (908g) robot out of two of them from Argos at £5 each and used the batteries as well. But even using cheap plastic wheels from a model car glued to the screwdriver bits [which works well] the drive units weigh 225 g each. So two of them will eat up almost half of your weight allowance.

According to my antivirus those links are trojans and I can't open them.

Ditto, thank god for Avast

I used cheap cordless screwdrivers for a 3kg sumo bot at the UKRG. Was a bargain really as they were £3.99 each and that gave me my motors and batteries. Weighed about 1.27kg or something total but it was slow and I found grip to be poor, although I was using narrow wheels. But you get what you pay for I suppose. They are weighty though as mentioned but may work quite well if you gear one down for use as a lifter weapon or something.

norton stopped it as well

well try going to the main site http://www.robotkitsworld.com, going to motors for the motors, wheels for the wheels and hardware for the motor brackets. Virus checkers can often see question marks in links as an issue.
