>>6154167Have you tried counterbalancing? Just pose Redhawk all bent over while Rider 1's putting all his weight in. Then have them balance against each other.
Here, I did this in like, 5 minutes, so the photo quality's not great. Most of those 5 minutes was just to fiddle with them until the sweet spot's found. Once they're counterbalanced, they're fairly stable for the purpose of photo taking.
