I am looking for help in determining the best rotor to fit in my TX472MDP tower. Have a new TX2 but the diameter is too great. I'm turning a Hygain TH11DX only right now but would like to add a smaller 40 meter beam eventually. Already have a new Green Herron controller. What will fit in the tower? Alpha Spid?
