I have a hexacopter iv built. Tried setting up in mission planner as i thought this was the only way. Then found QGC. Had no issues what so ever using QGC. I have retracts and led lights which connect to aux ch on px4. For the life of me i cant configure them.read through the instructions and searched on here but getting no where fast. Any good simple videos on how to do this. Thanks in advance.
