Getting this design to work at all was a huge mess aerodynamics launching tube everything is a pain but i got it to work to the best of my ability and its pretty cool so to use push down all the way on the trim and then give it full throttle form that point wait until the engine is running at full power then press act one immediately push up all the way on the vtol and now your flying but theres one more step you must quickly put the trim to neutral before the ucav loses control and then you can fly for as long as you want! Disclaimer this is not an easy plane to fly once its in the air because of the design of the airplane it can lose control if you go inverted for long periods of time
