If you are as much of a fan of the Solarbotics mini metal gearboxes as we are, you'll be pleased to know we've just brought in a nice complement to family - the GM20!
The performance of the GM20 makes it fit between the GM11a and GM12a, but more notablyl, it has a sealed gearbox. No more cat whiskers getting caught in the gearworks! No more cleaning out dust-bunnies and re-lubricating with exotic muskox oil! And it makes the gearbox even more resistant to side-loads.
These also have a beefier set of mounting holes, threaded for 2-M1.6 metric screws. Yes, it can a pain to find metric screws (sorry).
