Steam 700 V3 RC Helicopter Kit With Propeller/Without Propeller

The modular and split helmet can be opened quickly during commissioning and maintenance. It has good streamlined aerodynamic appearance and energy absorption collapse effect; It is of great help to the heat dissipation and protection of electronic equipment; The multi piece armor design has extremely low cost and loss; Bright colors and stickers derived from Taoist Chinese culture provide good recognition and beauty in the air.

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.

In 2011, we pioneered the use of angular contact bearings (tl8023) on helicopter models, which are now used in different parts by many manufacturers. This time, two double row angular contact bearings are also built in the rotor blade clamp seat, which can bear large radial and axial load, thus ensuring the function of the main rotor swinging the hinge

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.

The robust outer disc of the spider also uses double row angular contact bearings to meet the load requirements of the current mainframe on the spider, and the inner disc uses high-precision fisheye bearings. All ball joint threads are increased to 3.0m to avoid the problem that small-size threads are easy to slip. The unusual 700 long ball joint design enlarges the ball diameter to 5.8m, and specially customized large-size 5.8m ball joint buckles to avoid the interference between most helicopter ball joints and ball joint buckles in the market

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.

Standard stainless steel explosion-proof universal head buckle; Standard equipped with vulnerable metal steering gear arm; Design of suspended crosshead guide plate; All equipment wiring shall be protected.

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

In order to be lighter, stronger and more attractive, today’s 700 uses a new type of plate. Its interior is made of composite materials, which improves the compressive strength by about 5%, and its weight can be 20% lighter than that of pure carbon fiber. However, this material is too expensive, so we only provide standard battery panels and some parts. The new fuselage side panels need to be purchased and upgraded separately.

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.

The integrated battery board and the integrated motor base bring a lighter, better and more reasonable structure.

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
