Blade Revolution 235 CP RC Helicopter with SAFE is a mid-sized, ready-to-fly collective-pitch helicopter designed for stable handling and exciting aerobatics. SAFE (Sensor Assisted Flight Envelope) technology provides angle limits and improved self-leveling in Normal mode to help prevent crashes, while non-Normal flight modes offer full-range control for inverted flight and advanced tricks, with Panic Recovery to bail out if needed. It’s offered in Ready-To-Fly Basic and Bind-N-Fly Basic configurations, with the RTF Basic version including everything needed to fly in one box except a battery and charger, and a BNF Basic option available for pilots using their own transmitter. Durability and performance are built in, featuring a flybarless AR6250MHXD flight controller with AS3X and SAFE technologies, digital metal-geared cyclic servos, an aluminum swashplate and rotor head block, and a larger tail boom for added rigidity. A more powerful brushless main motor and tail motor drive responsive flight, while compatibility with 3S 850mAh Smart LiPo packs (and similar non-Smart batteries with IC2 connectors) enables telemetry to compatible Spektrum transmitters via the Dual Smart ESC. A full line of replacement parts is available, and optional upgrades such as carbon-fiber blades, aluminum blade grips, night-light kits, and color canopies let pilots personalize the Revolution 235 CP to their flying style.
