RE: decision for the DSM2 Alpha
I'm in! Mine is on backorder. Hopefully the late August date is accurate because I too would like to be flying this in September. As far as accessories, I'm going to stop by Brands Hobby in Providence around the beginning of September to get everything I need.
I have a Spektrum DX6i which I will use as the primary TX and I will use the DX5e for a buddy box.
Good luck with yours!
