Slope Soaring F3B F3F Control Design Eagle Butte is 700 high and a mile long. Spring and Fall are excellent times. This is a good comparison of different kinds of sailplanes their control systems and how they work on the slope.
A review od the FMA DS300 MBB Digital Servo. This is programmed with manual movement of servo arms when the servo is off. The servo end point center and reversing are all adjusted with manual movement of the servo arm. Turning the radio on and off with the transmitter off programs the servo. Therefore a Simple Y Inch harness allows two servos to be driven from one channel. Driving voltage can be between 2.5 and 12.6 volts. It has a digital filter and a 90 degree standard range and a 180 degree expanded range. A comparison was made to the Hitec 605BB. The DS300 drives full power with the smallest deviation from target position. The 605BB drives in proportion to the deviation. Prices are similar.
A switch design using a NiRod that exits the FG fuselage under the wing and back by the trailing edge allows the scale sailplane to be turned on and off without having to disturb the canopy or show the switch.
