Question regarding the belts
April 26, 2007 03:14AM
Hi all,

I have a question regarding the belts being used in the Darwin design. I have been at a local model shop where they sell parts for remote controlled toys. They have a belt that normally is used for RC helicopters to drive the tail rotor, which has a different pitch (approx. 5-6mm) then the belt listed in the BOM. They also have matching (plastic) pulleys. Both are reasonably priced (4 euro's/belt, 3 for the pulley).

I *think* this shouldn't make any difference, but would like to make sure, before getting 4 of them and find out later it does. I have ordered (and expect to arrive today) the stepper motors as listed in the BOM (ST5709M1208 from Nanotec) which will be used.

as long as the belts are the proper length, and the toothed pulleys are approximately the same diameter, i think you should be fine.
