Technical Performance
The Revolution 235 CP represents a significant leap forward in collective pitch RC helicopter design, combining proven engineering with modern brushless motor technology and advanced flight control systems. The dual brushless outrunner motor configuration—with a 3400Kv main motor for lift and rotor speed, paired with a 3600Kv tail motor for precise tail rotor control—delivers smooth, linear power delivery that responds instantly to your inputs. The Spektrum Smart Lite ESC with separate 15A main and 8A tail channels ensures that both motors receive optimised power delivery, whilst the intelligent ESC firmware prevents brownouts and protects battery voltage sags that could cause loss of control. The AR6250MHXD flybarless flight controller integrates a three-axis attitude gyroscope with the AS3X stabilisation algorithm, continuously monitoring and correcting the helicopter's orientation many times per second to maintain level flight even in turbulent conditions. The receiver with DSMX/DSM2 compatibility provides secure, full-range control up to 1.6km away, using spread-spectrum frequency hopping to resist interference—a critical safety feature that makes flying in populated areas or near other RC activity much safer. Construction quality throughout is excellent, with precision-machined components, ball bearings in critical areas, and reinforced composite materials selected for durability without excessive weight. The complete package weighs just 450 grams, making it light enough for smooth, responsive flight characteristics whilst remaining robust enough to handle the crashes and hard landings that inevitably occur during the learning process. Battery compatibility with standard 3S 11.1V 850mAh LiPo cells means you can purchase affordable batteries from numerous suppliers across the UK, and flight time typically reaches 8-10 minutes depending on flying style—aggressive 3D flying will reduce this, whilst gentle hovering practice can extend it beyond 10 minutes. This is a genuine brushless RC helicopter built to professional standards, delivering performance and reliability that justifies the investment.

Frequently Asked Questions
- Is the Revolution 235 CP suitable for complete beginners learning to fly collective pitch helicopters? — Yes, absolutely. The Revolution 235 CP is specifically designed as an entry-level CP helicopter, with SAFE mode providing automatic stability and envelope protection that prevents dangerous manoeuvres. The flybarless system is much easier to control than traditional flybar designs, and the three flight modes allow you to progress gradually from basic hovering through to advanced 3D flying as your skills improve. For nearly a decade, the earlier Blade 230 S was the number-one choice for learning CP flying, and the Revolution 235 CP improves upon that formula with better durability, easier controls, and more advanced flight modes.
- What battery does the Revolution 235 CP require and how long will it fly? — The helicopter is compatible with 3S 11.1V 850mAh LiPo batteries with IC2 connectors. This is a very common battery size available from numerous UK RC retailers, making it affordable and easy to find. Flight time typically ranges from 8-10 minutes depending on flying style; gentle hovering practice can extend flight time beyond 10 minutes, whilst aggressive 3D flying and stunt manoeuvres will reduce it to 6-8 minutes. Having at least two or three batteries available allows for extended flying sessions with brief charging intervals between flights.
- Does this helicopter require any assembly or setup before flying? — No, the Revolution 235 CP arrives completely factory-assembled and flight-tested, requiring absolutely no assembly, calibration, or setup work. You simply charge the battery, bind your Spektrum transmitter to the receiver (following the simple pairing procedure in the manual), and you're ready to fly. This out-of-the-box readiness is one of the major advantages of choosing a ready-to-run BNF (Bind-and-Fly) model.
- What makes this helicopter easier to fly than older CP helicopter models? — The Revolution 235 CP benefits from three key improvements over older designs: first, the flybarless flight control system with AS3X gyroscope technology automatically stabilises the helicopter's attitude, eliminating the tricky balancing act of traditional flybar systems; second, the SAFE flight envelope protection in Normal mode prevents dangerous manoeuvres and maintains stable, controlled flight; third, the brushless motor system provides smooth, linear power delivery without the lag and dead zones of older brushed motors. Together, these innovations make the learning curve much gentler and more enjoyable.
- What is the difference between Normal mode, Stunt 1, and Stunt 2? — Normal mode includes SAFE technology, which provides maximum stability and automatically prevents dangerous manoeuvres—this is the recommended starting mode for beginners. Stunt 1 and Stunt 2 modes disable SAFE and provide increasing levels of aerobatic freedom through the AS3X system, allowing experienced pilots to perform aggressive manoeuvres, flips, and advanced 3D flying. You can easily switch between all three modes at the flip of a switch on your Spektrum transmitter, matching the flight mode to your skill level and intended flying style.
- Is this compatible with my existing Spektrum transmitter? — Yes, as long as you have a full-range 6+ channel Spektrum DSMX or DSM2 compatible transmitter that is programmable for helicopters. The AR6250MHXD receiver will bind to any compatible Spektrum transmitter, making it easy to add the Revolution 235 CP to an existing RC fleet. If you don't have a suitable transmitter, Spektrum transmitters are widely available from UK RC retailers.
- What is SAFE technology and why should I care about it? — SAFE (Sensor Assisted Flight Envelope) is exclusive Spektrum technology that uses the flight controller's gyroscope and accelerometer sensors to monitor the helicopter's orientation and automatically prevent dangerous attitudes. If you inadvertently command too much pitch or roll, SAFE automatically limits the control input to keep the helicopter within safe flying parameters. This acts as a safety net for new pilots, dramatically reducing crashes caused by control input errors and building confidence during the crucial early learning stages.
- Can I use this helicopter outdoors and what are the wind limits? — Yes, the Revolution 235 CP is designed for outdoor flying. As with all RC helicopters, wind conditions matter significantly; calm to light wind conditions (below 10 mph) are ideal for learning and precise flying. Stronger winds can make control more difficult and unpredictable, especially for beginners. Many UK flying clubs have indoor facilities for flying in poor weather, which can be invaluable for practising during winter months.
- What is the range of the radio system? — The Spektrum AR6250MHXD receiver provides full-range control up to approximately 1.6 kilometres away, using DSMX frequency hopping technology to resist interference from other RC equipment and wireless devices. In practical terms, this range far exceeds what you'll ever need for CP helicopter flying; the limiting factor will always be your ability to see and control the helicopter, not the radio range.
