Feature:

The fixed seat of main rotor adopts colorful two-color signs to mark the direction. When adjusting the length of pull rod, it is not easy to recognize the wrong direction. T-shaped inclined support reinforced structure, two-way lock firmly hold the main shaft, so as to meet the stringent flight load-bearing requirements and effectively improve the flight stability. The ball buckle is equipped with stainless steel explosion-proof ring to prevent cracking during violent flight.

The two main rotor clamping arms correspond to different flight feel, so that different levels of pilots can adapt to the accuracy of control. The high-precision injection molded horizontal axis positioning rubber ring is installed with a double-layer polyurethane rubber ring with a double-layer hardness of 95 ° and a specially designed horizontal rubber gasket, which can effectively reduce the vibration of the rotor, bring the swing hinge effect and meet the stringent flight load-bearing requirements.

Accuracy reaches φ 14.990mm Φ The 15mm laser ruler spindle can not only facilitate the visual positioning when installing the main gear of the synchronous wheel, but also make the spindle fixing ring have better friction fixation. In 2010, we first launched the integrated spindle bearing seat to ensure the concentricity and reduce the helicopter body vibration (tl45088). Today, we continue to use this excellent design, and the upper and lower bearing positions continue to use angular contact bearings.

What makes the 700 different is that it has three large gear discs of 125t/127/129t/ and three motor teeth of 12t/13t/14t. It can form more dense transmission ratio parameters within the effective gear ratio range, better correspond to motors with different kV values, and fully squeeze out all the performance of the motor. The oblique large gear disc is machined by high-precision CNC gear hobbing, and the tenon and mortise design of the large frame is enhanced as a whole, resulting in a lighter and stronger structure. The metal center seat uses a one-way overrunning clutch and a wedge block structure to clamp the main shaft. Its locking force is four times that of needle type one-way bearing, which can reliably lock the main shaft

The upper and lower fuselages are connected by metal block mortise and mortise module components, and the two-way embedded design can be fixed with only two screws, which is as stable as a rock. 8mm diameter carbon fiber tube tail support assembly, T-shaped structure, multiple mortise and tenon design, firmly locking the tail tube, effectively improving flight stability and tail locking effect.

In december2010, after we first launched the integrated metal tail gear box (tl2671), many manufacturers have adopted this structure. The utility model has the advantages of solid box structure and high concentricity of tai
