Stupendo's arms and legs will move around as he flies through the air. If they comes into contact with an electrode, you will still be fine. The only problems occur when Stupendo's body collides with an electrode.
To getting longer distances, know where exactly your rope will land. When you tap, Stupendo shoots the grappling rope with some distance between him and the where the rope lands. Knowing that distance is important to determine your swing arc and velocity.
During intervals in the levels there will be no electrodes. Instead, there will be many green rings floating around. Have Stupendo swing through them to get bonus points.
Level layouts are static, allowing you to memorize obstacle and ring locations. Note: The daily challenges have new layouts each day.
