I don't know anything about the bolt on kit (with the motor hanging out the side), other than I have seen pics but no-one seems to run it. It doesn't appear to be something worth spending money on in my eyes though, just thinking about the COG being all the way off to the side is bad enough.
As for programming the speedies, the suited esc seems to be the XP3a with blheli firmware. You can program it yourself with the correct gear, and a search on the forums will tell you all the gear needed.
I have the AD mild kit, what batteries other than the stock, do you recommend?
