Cannot Transform Skeletal Mesh Pawn In Editor

I started a new project using FlyingPawn template with C++ and I changed PlaneMesh from StaticMeshComponent to SkeletalMeshComponent and gave the reference for the SkeletalMesh object. The problem is, though the Pawn is visible with assigned SkeletalMesh in editor, I cannot transform it anyway in editor and when I start the game nothing happens, no input and no movement happens at all. What could be the problem?
