This is just the alpha version. Hard to control and not easy to start (you have to start with the solar pannels deployed!). If you want to start you have to set the trim up directly after you spawned in the world. Then use roll, pitch and yaw to stabilize the ascend. When you arrive at the desired hight, you can gather some speed with throttle. Due to the solar panels it´s not ment to fly fast in the lower atmosphere so don't worry, it´s only 28-35 mph. Another thing is that it is not very agile. The best thing you can do if you want to turn is to keep roll and yaw simultaneously pressed while keeping the nose down with pitch. If you want to land you have to land with the solar panels deployed or closed shortly before touchdown. But these are all things I want to change with the next version. If you have got any advise please don't hesitate to contact me.
