When GPS feature is enabled, CH3 and CH4 are used for GPS connection.(CH3:TX, CH4:RX). When using PPM
receiver, these are normally unused, with standard receiver, connect AIL to 1, ELE to CH2, THR to CH5, RUD to
CH6, and AUX1/2 to CH7 and CH8.
When using PPM receiver, CH5 to CH8 can also be used as motor or servo outputs, depending on frame type and
configuration.
③Bootloader pads: ***ONLY USE IF GUI CAN NOT CONNECT TO SKYLINE32. This is not required for
normal firmware updates. When upgrading firmware, use tweezers to short pads together and power
SKYLINE32 on by USB cable. After power LED indicator turns blue, then remove the short. Firmware updated
tool can then be used to reload firmware.
