This is the Gaui NX4 Nitro "Combo A" Helicopter Kit. This combo pack includes the Gaui Mini VBar flybarless controller, four GS-303 high voltage brushless servos, and one GS-304 high voltage brushless servo. Plus, Gaui throws in a set of carbon fiber main blades to sweeten the deal! In a market dominated by large 700 & 800 class helicopters, the Gaui NX4 is a unique design concept that redefines what makes a nitro helicopter fun. The first machine of its kind, the NX4 blends 425-460mm size blades, a 37 size engine and mini size servos to deliver a power to weight ratio on par with 90 class heli's! When you combine this power to weight ratio with its "electric feel" gear ratio delivering gobs of low end torque, and 6+ minute flight times, 450/500-class electric heli's just dont stack up. Bobby Watts did his homework, and has produced a machine that is easy to setup, and forgiving for newer pilots, but can still be hammered by 3D pilots who want to put on a show. Pick up a Gaui NX4 and see how much fun small can be.

Features:

  • First production model of its kind, 425mm Nitro powered by GAUI 37 Engine
  • Extremely easy to tune engine
  • 220cc/9oz fuel tank provides 6.5 min+ flight times, compare to 4 min average electric ight times
  • Incredible fuel economy allowing close to 15 flights/gallon of fuel
  • Excellent power to weight ratio similar to most .90 sized Nitro Helicopters
  • Simple, robust, reliable frame construction
  • Carbon side frames use the same part for both left and right sides
  • Plenty of frame space for mounting electronics
  • “Electric feeling” gear ratio provides excellent low-end torque and is very forgiving for inexperienced pilots
  • Many parts shared with GAUI X4 and GAUI X5
  • Direct Servos to Swash for 120-degree CCPM providing extremely easy setup and operation
  • Adjustable servo mounting blocks for precise CCPM operation
  • Accommodates “Mini” sized servos
  • 8mm Main Shaft, 6mm Head Axle (spindle)
  • Stylish pre-painted FRP Canopy
  • Designed by GAUI R&D Department, Bobby Watts
