Black Horse Viper MKII/120mm HSDJETS Fan 640kv 12s Maiden flight

From my Royal fleet, “Princess Monica.”Beautiful Jet. One of the smoothest jets I have ever flown. I went extremely beyond manual CG recommendation. 200mm from leading edge. Quick 2 min flight. CG is almost perfect for my liking.

[@andystoybox1723]

Nice ! 👍🏻

How large is the opening at the rear of the plane?

[@smokeymountainrctravisThompson]

Wow it's big. Nice job bud

[@drmrjon]

Two questions. Are you using the inlet ducting that comes with the kit or is it open duct. Does the kit COME with the retract module or is it puchased separately

[@comeflywithmerc]

I cut the intake duct just passed the battery tray and left the nose open for air flow. I purchased the retracts from motionrc and added jp hobby main wheels with brakes and nose wheel.

Great video! Many thanks! I have the same plane and still deciding which fan to install. I am very confused (too many options…) Are you happy with the HDSJet 640KV? How much flight time do you have? Thanks again!

[@comeflywithmerc]

Im loving this fan unit! Super powerful. I just wanted to trim and land. Im thinking 5min + with throttle management and 4 heavy on the throttle. I’ll let her loose on the next one.🙏☝️✝️
