Andy,

The manufactuers do not publish a load figure although they are rather well made. The load would have been expressed as torque so whilst you say 500-600 grams, you would need to specify the distance of the load from the centre of the output shaft of the gearbox. As I'm sure you will appreciate, there is a big difference in trying to lift a load say 2cm from the output shaft to say 1m from output shaft.

How far is your load away i.e. diameter of the pulley or length of the arm?

Hello
Im building a 1/10th scale A27m cromwell mk IV cruiser tank. Your (1410-011) Technobots Feather Gold 12V 150W would be perfect to be the drive if i could find a 25:1 reduction gearbox, ive looked into building my own using sprockets/chain and/or gears but the construction gets heavy and unwieldy. Do you have such a gearbox or know where i might be able to get one?
Cheers
Brendan

Brendan,

If only! We would love to be able to help but so far we have had no luck in finding a gearbox at a suitable price. Industrial gearboxes are simply far too expensive for the hobby market.
