ROK Sportjet
Rok Sportjet
Designed by Luc Dietvorst and R.Bulk
For 100mm Midi fan Evo edf and 6-8 cells HV6000 (2 packs 6000 3 or 4s needed)
Why a 100mm fan ?
The 100mm gives a lot of thrust
We advise the 6s Midi Fan Evo 100mm with HET 700-75-1750, or 8s hetrc edf 700-75-1400
The Rok can be fitted with a 90mm midifan evo HET 650-68-1600 with some adjustments
The Rok is easy to fly but not for beginners or beginner builders
The Rok is a lot of work to build , but very rewarding
