SK-720 SK-GPS SK-LZR
Boxes opened but not mounted to heli. $595 shipped USA
The SK-720 is one of the most advanced and full-featured helicopter controllers available today, ready for beginners and professionals alike. Combine it with the SK-GPS2 module, and you have a powerful auto-rescue and aerial photography system for single-rotor, tandem-rotor, or multirotor helis.
The SK-GPS Version 2 is designed to maximize solid signal reception as priority #1. It has a huge 35mm patch antenna, double filtering, is fully shielded against RFI, and uses the latest ublox GPS chipset with a 10hz update rate.
The SK-LZR will automatically be used instead of the SK-GPS’s own altitude sense, as long as the heli
is within 20m (65 feet) of the ground, and is within 30 degrees of level.
The SK-LZR is accurate to roughly 2cm (1 inch). This is much better than the SK-GPS’s own
barometric altitude, which is only accurate to about 10cm (4 inches) and subject to drift with
changing weather conditions, and the effects of rotor disk wash.
