RE: 3 1/2 Mini Ultra Stick Rebuild
As I composed my prior post I wrote 70+ mph, then removed the plus because I wasn't sure, but I think with the right prop and wind you could push 80.
Whatever it does. it will undoubtedly be faster than any other random thousand Mini Ultra Sticks, maybe the fastest of all time. So get that .25 running good and keep us updated on your progress.
