Manuals & SupportA "Hyper" engine for hyper heli performance!
The 50SX-H Ringed Hyper is ideal for 50-class helis, with improved combustion efficiency for super-stable hovering and aerobatics.
- For over-the-top flying excitement, the 50SX-H Ringed Hyper engine is the clear favorite!
- Actually mounts in the same space as a .30-size application.
- The 60LH carburetor features 1.5mm more bore, to increase overall power.
Besides good looks and excellent cooling, the 50SX-H Ringed Hyper engine's machined blue alumite heat sink head also boosts combustion efficiency for more power stability.
The Hyper version weighs less than the 50SX-H, but delivers more horsepower for higher rotor speeds.
