Add To Wish List Tech Notes
The Raptor G4 90-Class Nitro Helicopter started with a clean sheet of paper and no preconceived notions on how to engineer a top-of-the-line nitro machine. Backed by Thunder Tiger's commitment to excellence, this heli is equipped with the latest advancements — including the Quick Calibration System, a helical main gear and an all-metal rotor control system — and it's surprisingly lightweight as well. With every 3D and F3C competition the Raptor G4 enters, it sets new standards and earns more and more admirers.

  • The Quick Calibration System makes setup a snap.
  • A helical main gear transfers torque more efficiently and provides more surface area for greater strength.
  • One-piece machined aluminum tail gear box.
  • Hollow 15mm hardened main shaft.
  • All-metal rotor control system.
  • A wide +/- 15° collective pitch range.
  • Equipped with a 135° swash plate, with an optional 140°.
  • At 9.7 pounds flight-ready, the Raptor G4 90-Class is lighter than comparable nitro machines.
