The foams are about 1 and a 1/4 rover foams and a 1.9 CI foam all stuffed in. Nothing fancy and I just put it in there really cause I don't have anything else at the moment. I will probably pick up some new CI foams down the track to try out, but we'll see how this go. Sorry I didn't get any weights as it seems the scales have gone walkabout Oh and finally BCs don't make for easy mounting on these wheels, it took me about 10 tries before I perfected the method
Made a few amendments to my original knuckle design, and came up with this. Major advantage of extra wide hubs is I can have a fairly similar amount of weight to my old design, except all below the axle centre. As pictured, according to inventor, is about 190g. So up to 380g all up.
Forward progress is good. It appears that you are moving right along. From your list one can only assume that you are building a custom crawler? The wheels look nice. Not sure of exactly what your going for with this project, but it looks interesting enough. Thanks for sharing with us.
