You see these on a lot of gimbals, but you can hardly find them available for sale separately. What do you think they mean with the weight specification?
The products page, like to many Chinese online shops, is very scarce of information. They sell 100g, 200g and 300g versions, although I only found the 100g and 300g models. So is the 100g *rating* for each or for the set? Then the next question is if it's for the set the 100g seem to come in a 2 each pack but the 300g seem to come in a 4 pack. So if it's 100g for 2 pieces then is it 200g when you use 4?
I doubt there is anything scientific about the weight rating. I suspect it's an arbitrary number bases on the harness of the rubber (durometer rating). I think it's safe to assume that any specification is based on four grommets since it would be impossible to make a stable configuration with only two. Three would be possible, but it wouldn't make much sense to rate it that way. If anyone is going to order these, I wouldn't mine getting in on the order for a few to play with. ...Tiger
I am planning to order some but don't know when. Probably in a week or two. I will let you know before I order. If you order before me I would also like to get in on the order. Did you see this plate: http://www.fpvmodel.com/_p524.html ? It has 8 damper balls and seems to be a universal type mount.
