If you are interested in flying FAI S9A Helicopter duration, these are all you need to add to your SK369 airframe. Hubs are made from laser-cut plywood with metal tubing and are pre-assembled. Blades are laser cut from 1/16" balsa and will need to be formed and attached to the hubs. A carbon fiber shaft and rubber bands are also included. This design is designed for beginners but has a high-performance track record. It recorded a 3 minute MAX at the 2017 European Championships flying on an A motor and a 3 minute MAX at the 2022 Arizona Cup flying on a 1/2A motor. Design by Brian Muzek.
