The Green Herons will let you set stops. Put big black lines on the
display as do not cross lines. The rotor turns so slow you probably
would have a tough time damaging the tower but your milage may vary. I
love the Green Heron controllers. They are spendy but turn most any
rotor out there and fully programmable etc.
