It’s not only about building drones – it’s about passion. Today the weather conditions were perfect for soaring.
When flying plane drones, you always have to be ready for unforeseen circumstances and take over the controls manually.
The best way is to practice that with thermal soarer – fly VLOS, far from your position and estimate all aspects of flight.
According to FAI F5J rules, variometer is forbidden, so the only way to estimate thermals is to observe the airplane. Not easy!
