RVE Dubhe E700 Kit : MK70000
RVE Dubhe E700 Kit : MK70000Specification Length: 1360mm (excluding blade and tail blade) Height: 352mm Width: 190mm Blade diameter: about 1555mm (based on 700mm blade) Blade lengt h (single): 700mm (range: 680-700mm) Tail blade diameter: About 289mm (based on 105mm tail blade) Tail blade length (single): 105mm (range 98-110mm) Gear ratio: 9.33/1/4.89 Takeoff weight (12s-4500ma battery): about 4500g Motor specification: 4526-6mm shaft diameter (range 4035/4230/4235/4525/4256/4530) Motor kV: 500-540KV(12S) Electric regulation specification: 130A+(12S) Battery Specification: 3300-5000(12S) Design features: The parts adopt high standard processing requirements of military industry level, and the smaller virtual position ensures accurate control feel. The vibration of the whole machine is very small, which can give better play to the performance of the gyroscope. Ultra lightweight design brings lower electrical equipment requirements, longer flight time and efficient training effect, and can greatly reduce mechanical wear. At the same time of lightweight, the body should have sufficient rigidity and strength, which puts forward higher requirements for structural strength and part materials. Therefore, Dubhe star looks slender, but it is actually very rigid! The newly designed aileron free rotor head geometry not only increases the rolling flexibility, but also optimizes the self-discipline stability. The whole machine adopts T700 Carbon plate, and the tensile strength is 38.8% higher than that of similar products, greatly increasing the strength of the frame. The main gear adopts special material and cutting technology, which has the characteristics of high wear resistance and ultra quiet.The reinforced positive and negative tooth tilt disc control rod and pitch control rod have higher adjustment accuracy and durability. The tilting disc adopts the double disc bearing design with adjustable clearance, and its service life is twice that of the ordinary structure tilting disc. After several tests and adjustments on the size,belt pressing angle and torsion spring force, the front pressing pulley tensioner of Dubhe does not need the tail pressing pulley and will not slip. It can not only effectively reduce the transmission resistance of tail belt and prolong the service life of belt, but also greatly reduce the risk of belt fracture. The lightweight tail wave box system makes the center of gravity of the body more concentrated, reduces the burden of the elevator, and makes the forward and backward rolling action more crisp and neat. The widened tail support fixing ring and tail pipe fixing seat increase the holding force of tail pipe and are not easy to deform. The lightweight tail rotor clamp design can effectively reduce the tail steering gear load and improve the tail locking effect. The tail rotor pitch control system adopts double push structure to reduce the virtual position and greatly increase the safety. The motor mounting seat adds the auxiliary bearing seat of motor teeth to provide additional support and reduce the wear of motor bearings. The new material high toughness tripod reduces the damage to the body during heavy landing. Simple and reliable slide rail and snap fast battery installation mode, convenient and efficient battery replacement. Dubhe star head cover not only has a tensile shape and colorful coating, but also has the characteristics of high-efficiency heat dissipation of auxiliary motor. The convenience of disassembly and assembly is fully considered in the body structure, and the maintenance is convenient and fast. Multiple wiring holes are reserved on the side plate, which makes the hidden wiring more convenient and beautiful. The super large battery compartment and enlarged electric regulation mounting plate are designed to adapt to more types of batteries and electric regulation. While other brands of helicopters are still racking their brains to lose weight, Dubhe star has controlled the total weight of the whole machine at 4.5kg (12S 4400mAh 70c battery) if 12S 5300mah 70c battery is used, the total weight is 4.7kg. What advantages can lightweight design bring? 1. More flight time 2. Lower part wear 3. Faster response speed 4. Higher following degree 5. Give better play to the effect of gyroscope 6. Lower requirements for electronic equipment 7. Lower power consumption 8. Less noise 9. More efficient training effect
