For over-the-top flying excitement, the 50SX-H Ringed Hyper engine is the clear favorite! The Hyper version weighs less than the 50SX-H, but delivers more horsepower for higher rotor speeds. 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.
