AF25B manual AF25B 无人机说明书

INTRODUCTIONCongratulations and thank you for purchasing this product. You are now the proud owner of a state of the art radio controlled helicopter. With proper care and safe operating practices, it will provide years of service. Please follow all guidelines and warnings outlined in this manual and obey your local laws in regards to safety and RC flight regulations.WARNINGS·Whether this helicopter is set up as radio-controlled or autonomous, it should be handled and operated strictly byqualified personnel. Fully loaded with a 25 lbs payload, with agross weight of more than 70 lbs, it will do considerabledamage in case of an accident. Do all you can to minimize that possibility.·Follow maintenance procedures and guidelines religiously. A poorly maintained and handled machine is a recipe for disaster.You, the end user are solely responsible for safe operation ofthis machine. Copterworks Inc. is in no way responsible for any bodily harm or property damage caused by handling,transportation and operation of this product.·Familiarize yourself with the airframe thoroughly. Before every flight, look for anything loose, cracked, or otherwise out of theordinary.·Use only the highest grade electronic components including the radio system, servos, battery packs, etc. to complete theairframe. Replace components such as servos well before their estimated lifetime or at first sign of questionable status.·Use common sense and strict safety procedures every time you handle, transport and operate this machine.·Always perform a pre-flight inspection.·Always check to make sure no one else in the area is flying on the same frequency as you do. Always perform a range checkbefore flying.·DO NOT fly over people, property and pets. Keep in mind: at any given time during flight, pilot’s error, mechanical failure oran electronic glitch can bring the aircraft down.·DO NOT exceed the 25 lb maximum payload capacity.·Replace any damaged blades immediately- including tail blades. DO NOT modify blades in any shape or form.·Use the proper type and amount of two stroke oil to avoid overheating and engine damage.GETTING STARTEDUpon receiving airframe, look for any signs of damage incurred in shipping. Any such damage should be taken up with shipping company directly.The helicopter airframe is fully assembled, and shipped in four sections. Please follow included instructions to assemble these sections together. If in doubt about anything, please contact us for assistance.CG- CENTER OF GRAVITYIt is critical that the CG of the helicopter be set such that the airframe sits level when lifted by the blade grips. This should be the case regardless of where the payload is mounted- whether upfront as a camera mount or centered in the landing gear. A slightly nose-heavy airframe where the rear skids come off the ground ½-3/4 inch above the front skids, is still acceptable, but you must avoid a tail-heavy helicopter. In addition to front/back balance, you should also maintain a left/right balance on the airframe. Distribute and mount components of your payload so that this is achieved.INSTALLING RADIO GEARThe black electronics box is mounted on tail boom, behind the gearbox, and it will hold your battery pack, receiver, governor and voltage regulator. Use the supplied Velcro strips to mount your components.SERVO SETUPUse high torque digital servos for best results. The servo mounts will accept any standard sized servo. We highly recommend JR 8711 or comparable other brands, for cyclic controls. Use 28mm or slightly larger round metal servo wheels and the supplied ball joints on the first or second holes, starting from the center of the wheels for maximum torque.Never use plastic wheels on cyclic servos!The distance of center of servo wheel to center of the ball should fall between 8mm to 10mm (diameter of 16mm-20mm).Set your pitch curve as follows:Low stick: –2 degreesHalf stick: 5.5-6 degreesHigh stick: 9 degreesAny moderately quick servo, with ball bearings will be adequate for throttle control.FLIGHT BATTERY PACKSWe recommend that you use two flight battery packs with at least 4000 MaH capacity each, wired in parallel. Monitor your batteries closely and check them between flights. Use an on-board battery monitor and a battery checker, such as the Futaba BR-2000 between flights.GYROWe recommend the Futaba GY701 or comparable gyro, for best performance. Follow manufacturer guidelines for their setup and proper servo selection.GOVERNORWe recommend the use of a governor for a consistent rotor head speed. Please note that even when using a governor, default throttleand pitch curves with corresponding “ Fail Safe “, must be set up. Your helicopter has been shipped with an engine RPM sensing module which eliminates the need for using governor magnets and sensors. Simply plug the module lead labeled “ to governor ” into your governor. Set up the gear ratio at 6.42 and rotor head speed at 1450 RPM.GEARBOX OILFill your gearbox to a height of 3-5mm maximum, with 68 ISO gear oil (semi or full synthetic), available commercially. Use a small screwdriver, inserted through top opening, to check level. Over-filling will lead to leakage as well as overheating of gearbox. Change the gearbox oil first at 20 hours and then at 100 hour intervals.FUELMix 4 Oz per gallon(32:1)of Pennzoil(TCW3) 2 stroke 100% synthetic outboard marine oil with 87octane(minimum) unleaded gasoline. Try and make it a habit to mix your fuel on the day you will be using it. Even slightly deteriorated fuel will have an impact on the engine’s performance.Important:Use gasoline with no ethanol content! Even slightest amount of ethanol will immediately start deteriorating certain parts in your carburetor, leading to performance degradation and engine damage.If available, and whenever possible, use AVGAS (aviation fuel) for best performance.CARBURETOR SETTINGSThe carburetor needles on your engine are at default factory position. We believe those settings are a good place to start. Make fine adjustments as conditions require. Ambient temperature, humidity and elevation at location where you fly, will ultimately determine your settings. Follow engine manufacturer’s guidelines for more details on adjustments and care. Both needles should be within 2 ¼ - 2 ½ open.ENGINE BREAK-IN PERIODWe recommend that you run at least 3-4 gallons through the engine in flight, with no more than 15 lbs of payload. Vary the altitude and load on the engine as you do this, to properly have the engine components break in. Make sure you are running the engine with slightly rich needle settings- making sure some smoke coming out of the exhaust pipes is visible. Absence of smoke, is a sign of your engine running too lean.AIR FILTERClean air filter with compressed air at 10 hour intervals or more frequently if necessary. A dirty air filter will noticeably affect the performance of the engine. Replace as needed.GENERAL CARE TIPSMake it a habit to clean the whole helicopter after every flight. Use compressed air, paper towels and light degreasers. Do not use harsh degreasers or solvents on the ABS canopy.LUBRICATIONOnly two areas require lubrication for each day of flight:1. The main shaft- below and above the washout unit, throughoutits movement range.2. The tail output shaft where the tail pitch slider operates.Use light lubricants such as Tri-Flow.BLADE STORAGEBlades should be stored hanging vertically from the blade grip hole. Do not store them laying down horizontally for long periods, as this will lead to deformation.REMOVING ENGINE DRIVE BELTTo remove/replace engine drive belt:·Loosen tail boom clamp holding the tail boom support rods.·Loosen clamps holding the tuned pipes on to the tail boom.·Loosen the (4) ¼ inch bolts going through the gearbox and cross member.·Move the whole tail boom/gearbox assembly forward to loosen belt. You can now remove the drive belt. Make sure you do not crimp the belt while removing. Removing the cooling shroudcross member will make this step easier.Warning: When tensioning the drive belt, make sure you do not make it overly tight. While you are pulling on the tail/gearbox assembly for belt tension, look at the clutch bell/pulley unit and make sure you are not deflecting it by pulling too far. You should be able to push the belt in with fingers easily. Failure to observe this, will cause engine damage.The drive belt should be replaced at every 100 hours or sooner if it shows obvious signs of wear.REMOVING TAIL ASSEMBLYTo remove the tail section:·Remove tail boom clamp holding the support rods.·Remove tuned pipe clamps holding them on to the tail boom.·Remove tail boom ground wire.·Disconnect all wiring from the electronics box.·Loosen the green plastic tail boom clamps.·Slide the tail drive belt off the driver pulley (at the bottom of gearbox) and remove tail boom.·Repeat steps in reverse for reinstallation. Make sure you install the tail belt such that when main rotorhead turnsclockwise, the tail rotor turns counter-clockwise.LONG TERM AIRFRAME STORAGEIf you are planning to store the airframe for long periods, disconnect battery. Remove spark plugs, put some engine after-run fluid in each cylinder, turn the engine over a couple times to coat the cylinder walls and put plugs back.Scheduled maintenancePlease refer to the following table for service/replacement intervals of critical components. Keep in mind that extreme operating conditions will cause a shorter service life for most parts. Always perform pre-flight checks, looking for anything out of the ordinary and keep a log for hours flown. A post flight report is also recommended, and should include notes on any issues experienced during flight.Component 20 hours 50 hours 100 hours 150 hoursInspect Inspect/replace Inspect/replace Inspect/replace Auto-rotationclutch(pair)Clutch- shoes Inspect Inspect/replace Inspect/replace Inspect/replace Inspect/re-line Inspect/re-line Inspect/re-line Inspect/re-line Clutch bellliningInspect Inspect/replace Inspect/replace Inspect/replace Engine drivebeltInspect Inspect/replace Inspect Rotorhead- BallbearingsInspect Inspect/replace Inspect/replace Inspect/replace RotorheadPlastic ball linksInspect Inspect Inspect/replace InspectMain rotorbladesWashout unit Inspect Inspect ReplaceTail drive belt Inspect Inspect Inspect Inspect/replaceInspect Inspect/replace InspectTail rotorbearingsInspect Inspect/replace Inspect/replace Tail rotorbladesTail pitch slider Inspect Inspect Inspect/replace InspectGearbox gears Inspect InspectInspect Inspect Inspect Inspect/Replace Tail drive shaftsealGear oil Replace Check Check ReplaceSPECIFICATIONSTotal length w/o blades: 70”Total height: 28”Landing gear width: 20”Frame width: 7.25”Dry weight: 35.5 lbs.Gross weight: 25 lbs payload plus fuel 71 lbs.Main rotor disc diameter: 84.5”Tail rotor disc diameter: 15.875”Gear ratios- Engine/Head/Tail: 6.42: 1 : 4.69 Engine: Two stroke, 80cc Fuel: Gasoline/oil mixFuel capacity: 128 Oz.
