I had an old X Brace HDX589 that had a removable X Brace section for rotor
placement which allowed easy installation of the Orion 2800 or about anything
else. Installation of the Orion 2800 in my much newer W Brace HDX589 was
difficult (but doable) even on the ground with the tower tipped over. Turns a
DB36 on a tilt plate with an 80/160 inverted vee.
