1 Activates all the robotic arm functions, 2 activates the rotation of the arm, 3 activates the engines. When you fly, be sure to deactivate everything but 3. VTOL controls the bending of the arm (1), TRIM (up) extends the whole arm (1), THROTTLE controls the grabber (1), ROLL controls the rotation of the arm (2).The different activation group is so you can lock the rotation of the arm so you can do other things. If you retract the gear, which is reccomended when picking up things, it rests on feet to stay still. Your challenge is to pick up and transport this thing in front of the plane and transport it to another island. Comment and upvote if you like it if you did. This proves I can make just about anything fly...
