Technical Performance
The BLH Main Frame represents the engineering standards that Blade has become known for in the micro RC helicopter market. As the primary structural component of the Blade 120 S, the frame must balance lightweight construction with sufficient rigidity to maintain stable flight characteristics and support the aircraft's systems. The frame is engineered to provide mounting points for the 120 S main motors, accommodate the swashplate assembly for pitch and roll control, support the landing gear configuration, and interface with the tail boom assembly. The frame design incorporates mounting provisions for the canopy, which adds to the aesthetic appeal of the 120 S whilst protecting internal electronics. For those building or maintaining a Blade 120 S, this frame is compatible with all standard 120 S components, including the main motors, servos, batteries, and receivers from compatible manufacturers like Spektrum. The frame's design reflects the proven platform that has made the Blade 120 S a favourite among UK RC helicopter pilots, from those flying casual weekend flights to those practising 3D flying techniques.

Frequently Asked Questions
- Is the BLH Main Frame: 120 S compatible with all Blade 120 S models? — Yes, this is the standard main frame for the Blade 120 S platform and will fit all Blade 120 S helicopters. If you're looking for replacement parts for the Blade 120 SR or Blade 120X models, those use different frame assemblies, so make sure you're ordering the correct part number for your specific helicopter model.
- Can I use this frame to build a spare airframe? — Absolutely. Many RC helicopter enthusiasts maintain multiple complete airframes so they can keep flying whilst repairs are underway. This main frame is the structural foundation for building a spare airframe, and you can source the remaining components from RC Model Shop's extensive Blade 120 S spares category.
- What happens if my main frame is bent but not broken? — In some cases, minor bends in a main frame can sometimes be carefully straightened, but given the precision required for stable helicopter flight, if the frame has been significantly stressed or bent, replacement with a genuine Blade frame is the most reliable approach for maintaining flight safety and performance.
- Is this an original Blade part or a third-party replacement? — This is a genuine Blade main frame manufactured by E-flite, the company behind the Blade brand. Using original Blade components ensures compatibility with all other 120 S parts and maintains the engineering standards that make the 120 S such a popular micro RC helicopter in the UK.
- What other spares should I keep in stock alongside the main frame? — RC Model Shop recommends keeping a small crash kit of common wear and breakage items including main blades, tail rotors, main gears, feathering spindles, main shafts, linkages, swashplates, landing skids and bearings. This way, when you have a crash or hard landing, you can quickly replace the damaged components and get back flying.
