A must for begginers, keep your damage to a minimum while you practice your nose in hovering.
The rods are stiff Carbon Fibre with balls that spin so they don't get caught up and flip your heli.
Attach the feet with rubber bands and go for it.
(Sit the heli on the feet, hook the rubber band over the landing skid, wrap the band around the skid and training feet a few times then back over the end of the skid)
