Hey Chris, do you sell any of the aluminum parts individually? I had a sprocket get stuck on the J6 housing, and I couldn’t remove it without damaging the housing. So I wanted to see if there was a way I could get just that J6 housing, if that’s at all possible

I just spent the last four days building the control box and I want to say that the build manual has been a joy to use. There is a lot of work to do but it is ordered in such a clear and rational manner that the process just flows along. If you are reading about the AR3 wondering if it is a good project to start, I can say it is a fantastic learning opportunity. Thank you Chris for your meticulous efforts. I am having a great time! Cheers, Bob Welland
