Blade Revolution 155 CP BNF Basic with AS3X and SAFE
The Blade Revolution 155 CP is the next chapter in one of the most successful collective pitch trainer helicopter stories in the hobby — an updated, upgraded evolution of the legendary Blade 150 S that helped thousands of pilots learn to fly CP helis over nearly a decade. The Revolution 155 builds on that proven foundation with meaningful improvements across the board: better flight controller tuning for improved self-leveling performance when switching back to Normal SAFE mode, an updated composite frame with optimized servo geometry and upgraded servos for improved flight performance, a more powerful and lighter tail motor with a new tail prop for sharper yaw control, and a fresh new color scheme. The result is a heli that's more affordable, easier to fly, and more capable than its predecessor — and one of the most accessible entries into collective pitch flying available at any price.
Exclusive SAFE technology makes learning genuinely achievable. Normal mode provides angle limits and automatic self-leveling that help prevent crashes while you build confidence, while Stunt 1/Idle Up mode removes all limits for basic aerobatic maneuvers including loops, rolls, and inverted flight. Stunt 2 mode opens the door to all-out 3D aerobatics when you're ready. Panic Recovery is always available at the push of a button in any flight mode — your instant bail-out when things get away from you. AS3X works continuously in every flight mode to smooth out wind and turbulence for a locked-in, larger-helicopter feel. The factory-installed Spektrum AR6250MHXG flybarless flight controller and receiver are pre-loaded with a Smart Transmitter File that automatically imports all settings for NX and iX series transmitters during binding — getting you in the air faster than any other helicopter in its class.
The Spektrum Dual Smart Lite ESC delivers real-time battery voltage and telemetry data to compatible AirWare-equipped transmitters with both Smart and non-Smart batteries, and three digital metal-geared cyclic servos provide reliable, precise control throughout the full flight envelope. The Revolution 155 arrives 100% factory-assembled and flight-tested — ready to bind to your 6+ channel Spektrum DSMX/DSM2 transmitter and fly.
