I'm on the 6th floor of a condo in Mexico. Nice huge window to fly out and over the balcony. No trees or tall buildings near-by, just open sky calling me. There are regular power lines going to the homes and businesses below. No transformers near-by. Not flying over residential, planned flying along treed roadway. I can fly inside with 10 satellites on a cloudy night. My GPS location is dead-on. Should I switch to Atti mode? Just in case it randomly disconnects and initiates "return home". I only plan on a 5-10 minute fly around with a planned max distance of a 50 metres out and a planned max height of 100 metres up. -I'm reluctant to go high because the rc has warned me twice "weak rc signal" at 200 metres straight above me. But there were heavy electrical wires near me and I took off from a parking rooftop. (The home point was off by 30 metres ) And the flat part of the antenna was not directed at the phantom. The top end points were pointing at the phantom. I have since learned about optimal antenna reception.- Has anyone tried flying from a condo/apartment balcony?
