Thanks Greg and Steve.

If I understand one-way bearings and two-speed transmissions well enough from your descriptions and this this excellent site:
http://www.rctek.com/info_bearings_one_way.html
http://www.rctek.com/transmission/info_two_speed_tranny_design.html

then I think that means this single speed, non reversing tranmission is modifiable as Steve outlined.

But at only 6.25:1 and plastic, I'm a little less interested.

Thanks,
Amir
