We meet an issue of that when using gasoline engine on arduplane on Cube Orange Plus with 4.3.x Version firmware.
When we set ICE_ENABLE , ICE_OPTION set bit 2, the throttle did not working.
If we using 4.2.3 Version firmware, set ICE_ENABLE , ICE_OPTION set bit 2, the throttle working normally.
But Cube Orange Plus can not load 4.2.3 Version firmware as stable.
