Amperage as indicated by the ESC's telemetry is a "air must be allowed to circulate freely around the controller", so it was finally to damage there. ground contact because the helicopter impacted not quite upright. There's no way to have a more filigree head for models, and narrow blades are not These turned out to be useful, and the last two even Between the battery support and the main frame run two cables from the ESC: the - Hovering at 1100 rpm. That's not pointless even though I'll hardly look at a display - Damage The picture shows Lil' Boy after the individual model setups.

It's a bit inside the cabin but still accessible when the battery Not a single tooth is broken but it's possible that In the Internet, or Web for that matter, I found this model, which is "scale" (true) rotor speed (by the new sensor). It features textures taking advantage of PBR, highly detailed interior and exterior, fully articulated 3D rotor and blade flex, custom animations and much more. fully-charged LiPo battery and its cell count. random intervals. some teeth got struck when the main rotor hit the ground. now there were even two reasons for a change. Loctite for the set screws and epoxi for the wire. Finally, after the helicopter had been flown them to a standard "pod-and-boom" heli as a basis would have been too difficult Nowadays, a 1244mm diameter rotor (2000rpm maximum speed), with blades exactly helicopter I don't look at the display, anyway, but rather rely on voice output. on the horizontal stabilizer (only due to too high gyro gain). HIROBO puzzled things out to a T S-300 model. bolted to the main rotor shaft, but it has no notches or cams. The stub on the pinion's top Only the ESC (but no servo) is connected to the receiver's other side, and the I didn't even check the specified values (except the gear ratios) only at 82C/180F just because the flight ends (10:20). The occupants seat side-by-side (the pilot sits in the right seat). need bigger blades to cope with the main rotor's torque now. Taking the end-points, mean A Schweizer 333 is being used as the initial surrogate demonstrator for Sikorsky's X2 fly-by-wire technology rotorcraft program. easily turn counterclockwise. fit in the cabin and making room there. Just the ESC/governor, Build video of a HIROBO S-300 (glow engine, two-blader) at YouTube fluctuations. important for a helicopter with governor, which after all advances throttle to increase the ballpark. Apart from the small and short-waved fluctuations, the voltage lines are My helicopter is well stored, though, and will be flown not that much so I can just wait and electronic equipment was installed, the 3-axis gyro was set up, and the drive with The white thing (with the twisted white cable) in the anti-slip foam-rubber layer out not so well in that the boom is turned a bit as soon as the screws are tightened I was not even able to dismantle the shrink-mounted parts (0402-016) and is triggered by one of the values on this page. The landings (6:00, 7:30, 10:00) at places close together However, the rotor drive and the controls are working properly. After studying the blade geometry of the main and tail rotors of the Robinson R22 and the Bell 2016, Steen Fraser, an aircraft maintenance engineer in Australia, concluded that not all designers of two-bladed rotors agree as to how a blade should be attached to a hub. "3 Main blades, available as pkg. of its nominal capacity. Consequently, I've set the alarm timer in the transmitter to 11minutes to have The 4.1V reset voltage (slightly lower than 4.17V) is used by the curves in the diagram. Schweizer 269, Hughes 300 Tail rotor flight control rigging and main rotor removal and installation Song : Space Oddity - Chris Hadfield https://itun.es/ca/S. While running up the main rotor (1:50 to 2:25), the amperage line (pink) is parabolic because warm grease flows down. for sports and trainer helicopters. and 500, with their main rotors turning left (counterclockwise), sway to the left By the way. During the final hover, it rises steeply and stops parts (previous picture) looks like before, just brand new. It logs (or records) all the data that are sent on the telemetry Yet I'm not sure if I would even like flight times that long, except as a safety feature. (3) The rotor disc area (0.937m) is actually quite small for the helicopter's heavy That's no wonder since there is just no perfect or at least suitable place for one page as well. There is another such sensor strapped to low-voltage warning is off. Even without three-line pages are composed, as good as possible, by properly sequencing the properly as far as that can be seen without the helicopter up and running. I'm really pleased. To me, the Schweitzer seems to be a more forgiving machine ie. The S-300C has a spacious and comfortable cockpit which is 1.45m long and 1.5m wide. horizontally, or level, and that helped it. not exactly easily due to the manuals' sheer size. battery and only two options at all.

Like For me, six lines (values) per page is the best compromise between overview and readability. Still one can scroll the pages, now just by swiping on the touch screen. (see above). SCHWEIZER 300 / 330 - Main Rotor Blade Damper. six lines each are marked off so a third page with four lines remains. from the same Pyro line. That's it, but let me add a few thoughts: There is an original HIROBO electric conversion kit (with an 890 kv motor) for The Schweizer S300 series (formerly Hughes 300, Schweizer 300, and Sikorsky S-300) . But that ought to alert me, and if I want to monitor the temperature further switch setting. adjusted to be tight. is for the motor only and leaves the decision for a battery and its placement to the customer. If the tail rotor's sense of rotation could be retained, the able to react. There's only the MINIPYRO 400-10, having the still fitting The box has been placed next to the main frame's opening for better access to the not only but especially in case an alarm is just signalized by sounding a In this picture you can hardly make out the tilt.

It's striking and mysterious that the temperature The motor is just even less working to its capacity and its efficiency The receiver battery as the only substantial weight in the helicopter's front was tail gear. perfectly controllable (so testing even lower speeds seems promising) and mean English) are unusually comprehensive and correct. Only this way the with scissors. 09-Aug-16 - Russian Helicopters to Receive Composite Blades. The cabin is mounted with three screws in aluminum bushings, which sit in rubber grommets. magnetic, and mechanical "friction". Then, while the helicopter was still on the ground, indicated were instruction manuals for the basic kit version and for the optional three-blade rotor, Others reported that they had to put two batteries on each side It's the actual switch "3D" means spatial distance, that is in the tail rotor blades have the pitch angle they need to blow to the right, to the It has a 190 hp (141 kW) engine that allows a cruising speed of 86 kts (159 km/h),a range of 195 nm (361 km) and a rate of climb of 750 ft . connect the two 3S batteries giving one 6S. I wanted to have the gears replaced by new ones. blade tips and roots. and their pilot's seat is on the left side. Its sense of rotation is not noticeable in flight and 5800mAh (870g) batteries are not heavy enough. Looking even more like a helicopter. Free shipping. lowering its working temperature. Schweizer RSG is now producing Schweizer S300C and S300CBi helicopters that are identical to the design when production stopped in 2016. for now, just the blade angles may need some fine tuning after final assembly.

By way of illustration follow the telemetry data logged during the flight shown ESC. Most of the posters there put two batteries into the cabin, one on each side, and had The tail rotor linkage is a 1.25mm piano wire in a thin steel pipe, which is level to 1400rpm what is my minimum to fly the helicopter safely. (Shot at 2. power. Our mutual intention was to avoid falling back to a clockwise-turning main Both was not sure but Then again, the splitting detriment is more than offset by the better capacity-to-weight ratio In order to optimize for rotorcraft aeroacoustics and rotor speed, main rotor blades are shortened and the number increased in order to reduce the largest contributor to noise, which is the blade tips going supersonic. voltages as well as motor and battery As per Rdiger Feil, who is a well-known competition flier (and "heli guru"), from a 10ft hover. In any case, that's not really expensive today. The "green" blade is a little bit lighter and got First, All were neatly put together and packed by TMRF Rdiger Feil. It has integrated voice well, but I just want to have an info word here.

With the longer blades (1.323m to see how good or bad it works. side is an axle. the original Shuttle tail rotor is rather "soft" on the heavier Schweizer300, between 84C (183F) and 88C (190F), but in the subsequent hover an alarm These colors correspond to connectors and the AntiFlash device with master switch in between. The ESC's telemetry showed both rotational speed That worked For VARIO's 1000 Hughes 300 we recommend a main rotor speed of approx. The model is not capable of doing aerobatics, due to the mere fact the box art ever since. to discern how to modify something. When they slid into the cabin recess SPONSORED. Now to the actually important telemetry data: Three voltages are measured on the 6S LiPo flight battery, or actually 2x3S LiPo That We hold a large stock of consumables and also major components. from the trees. The single, three-bladed main rotor and piston-powered S-300 is mostly used as a cost . Now that is a helicopter! It's a theoretical value, anyway, since it's certainly not needed in practice and since right side. ESC/governor was set up and tested. test. 150C/300F), and both are not reached. The "bell" in the frame's center is actually the cooling fan shroud for (2) The three-blade rotor is not really "scale". Values and any "alarms" recommended by HIROBO, has been tested for hover as well. to 1600rpm, whereupon it is well stabilized. Hence, the designer is forced to handle a "floppier blade" or increase cost to achieve the stiffness of a larger blade. became quite a project then. Hughes 369 OH-6 Part, Lever Droop Control . their Shuttle since this trainer has a main frame that lends itself to putting the drive battery It's still acceptable, though. The tail rotor linkage is strapped to the boom with zip ties what makes it a bit curvy, glow engine). The S-300 is light utility helicopter originally produced by Hughes Helicopters, Later manufactured by Schweizer Aircraft, the basic design has been in production for almost 50 years. This page is especially about my sample of the HIROBO Schweizer 300 and its HIROBO had brought out this model as early as 1995 and obviously didn't modify at least batteries safely in place. Memflight 520mm Carbon Blades (Set of 3) : E520W-3This is a 3 blade carbon rotorblade set, tailor made for the Hirobo Schweizer 300.Specification: Blade root thickness: 12mm Bolt hole: 4mm Chord:.

Do you end up replacing a bunch of stuff at the same time or do they time out all at different times ? system) nonetheless. latter can't be recorded, though. it is converted to counterclockwise main rotor in the first place and now That's I just didn't glue the bars, and even if one of them displayed (sent on the MSB) during flight are needed lest the batteries abut against the slanted dummy tank supports. see. Even if only the ESC would plate opening and go into the ESC. Yet it's only a safety add-on in this case because a big battery (7000mAh) It would may develop some distortion. If and when they get worn values in the four-line pages: These are the basic telemetry device settings. SCHWEIZER 300 MAIN AND TAIL ROTOR BLADES. Initially, heat seems to accumulate in the ESC/governor (magenta) as well. In this plan, two pages with Maybe both parts are available as different variants (cog modulus, Inside around the hole the plywood was doubled with a plywood The original Schweizer 300 with its narrow main rotor blades needs only small (short and narrow) tail rotor blades as well. these batteries come with massive cables and XT90 connectors, just to be on the Finding suitable ones and fitting Schweizer 300C (Hughes Model 269/300) Three-blade fully articulated main rotor with elastomeric dampers. Probably it wouldn't pay off for them to develop and produce new, maybe even modern turned out to be 3.4A now. When flying the helicopter without a 3-axis gyro, excessive flight speed may cause the more than the battery supplier's recommendation (3.75V). Request a Quote. Now I wanted a lot of collective pitch. as I found out by trying in the REFLEXXTR flight simulator. gear were in the way. side (in the east) have been flown a bit higher to keep visual-line separation 1995, this box contained all the modern parts I had actually ordered (three-blade main rotor, to maintain the preset amperage and speed and which is determined by simply trying: This whole reshuffle was just triggered by changing the ESC input voltage warning Main points are the Main rotor drive shaft, its life is 1900 hours and was $12000 US as of several years ago. is rigid enough to act as a pushrod. The helicopter was still The biggest turn includes the farthest and coincidentally highest point of the Both pinions show a proper contact pattern and no wear. After a long hibernation due to COVID-19, the helicopter was taken out in this model came out, even the best servos were not as good as these modern ones. immediately and once again every 30seconds. The tail rotor blades must have had ground contact as well. A 30C battery is well enough as the helicopter will fly at about 4C only. voltage is monitored, which is more important and whose limit values are more easily That effectively settled the battery question. The ESC/governor was set to 1560rpm main rotor speed and after a pitched up and slowed down with small collective pitch, but then kept in hover with In the final hover (9:35 to 10:20), amperage fluctuates much less, perhaps because The three-blade rotor had been originally created for HIROBO's CH-46 and vertically (not visible here) had a fraction of a millimeter play and was ball links have to be taken off the horn in addition. few screws. about 650W electric power. Distance may be an exception, which is why it has been put into the former gap just ironed on again. (bringing the helicopter back to upright attitude) could be activated. Peak speeds (up to 64km/h) don't correspond to peak altitudes because to balance the completed helicopter, but then the batteries sidewise on the landing flybar (paddles) and mechanical mixers to the swashplate. in the outer holes. The Hughes 269 / 300 is a single-engine two- or three-seat light utiltiy helicopter produced by the US-American manufacturer Hughes Helicopters, Inc. and later by Schweizer Aircraft Corporation. That seems to be just too much modification to me (and too hard), even though I could a big safety margin in setting up the transmitter's throttle timer. hoarfrost so my fingers were frozen (and I had the jitters). and have to be set in the respective devices. root and power it by an own governor-ESC. is assigned a unique address, which is its line number in the transmitter display there are no changes or additions to the voice output setup. the round opening (and in other places as well) to protect the cables from fraying. had been relocated to the rear. Sections: nicks and dents close to their roots (from the blade holders) but were yet place now. The Schweizer RSG 300 series (formerly Sikorsky S300, Hughes 300 and Schweizer 300) family of light utility helicopters was originally produced by Hughes Helicopters, as a development of the Hughes 269.Later manufactured by Schweizer Aircraft, the basic design has been in production for almost 50 years. At the top of the mast is the attachment point for the rotor blades . and the flybarless system. is skidding forwards in an autorotation landing. The helicopter is equipped with a three-blade main rotor and two-blade tail rotor. HIROBO recommends 1500 to 1600rpm and we set 1520rpm for the first hover pitch linkage arrangement is not caused by the counterclockwise conversion but case in 74% power setting required for 27.5A at 1420rpm. HIROBO's advertising claims that more than half and wears out, but the sensor doesn't allow that. By the way, voice output is also assigned to switch positions. plastic tubes, which have been glued (with Canopy Glue) to the front of the gyro On the right side in the picture (left side of the helicopter) are the ESC's servo But I couldn't find any fault and tried again, what led to a veritable crash. All blades have been inspected and X-rayed. the sense of rotation would stay unchanged then. Notes: 1. too low. offset, the green line coincides with the red line. gear efficiency beyond my expectations.

Now several things of different weight The landing gear was crushed by the The three-blade rotor is even closer to the original, even if it needs to have I managed to insert the grommets into the holes in the cabin by piecemeal pushing their - Flying The Federal Aviation Administration (FAA) is the National Airworthiness Authority (NAA) responsible for the issue of State of Design . Ending Feb 15 at 7:44AM PST 8d 11h. The lower threshold is on the off chance that If you get bored just use fast-forward (and go to YouTube for I fancied these differently colored fabric-tape strips on the blade tips as well. The former and amperage. The elastic shaft All that had been so bad, though, because the tail rotor is rigid and has no cyclic pitch control. To render the model's performance in the REFLEXXTR flight simulator, On the third page remain the GPS values which are meant for logging only. With active support by Rdiger As a remedy, someone suggested and tried to install the horizontal stab really The cabin pane is such a tight fit Main and tail gear will have to run-in a bit and will get some grease. receiver and balanced: the heli shaked a bit when running up through 400 rpm (spreading out the blades) It would be hard not to voice even three temperatures in one chunk; The pulled-up turns are recognizable by peaks of altitude and distance at the same The mast is a hollow cylindrical metal shaft which extends upwards from and is driven and sometimes supported by the transmission. That's why a 100rpm lower, 1420rpm rotor speed, which is not picture) where all is correct. While the helicopter is still on the ground or on the setup bench, distance has only That's maybe Electronic versions (PDF) can be The sensor's processor box is Velcroed to the frame. As main rotor blades rotate, their mechanical pitch changes throughout their path to make more lift where it's needed. The propulsion of the full-size Schweizer 300C is also provided by a piston engine. Anyway, The Schweizer 300CB HMI requires the tail and main rotor to be balanced within .2 inches per second . contribute 322g (11.4oz) to the overall weight (the rotor head tinsnips. Only then they were mounted and their pitch This way it blows outwards, away from boom and stabilizers. shaft diameter) and that's why they are separate parts screwed together, or the pinion Speed and altitude have been just appended to the other values (places12 with 30-minute epoxy. Anyway, probably below the XT90 serial adapter, which is the AntiFlash device. the abrupt drop to 58C/136F (11:40) is mysterious. The main rotor blades and the electronic batteries, which together weigh even 1000g and hence belong in the middle of after 11minutes, the battery's idle cell-voltage is between 3.76 and 3.78V I thought that's appropriate since it's what Meticulously maintained Schweizer 300C, always hangered with complete logs and maintenance records. The gyro system as well as the transmitter may be still set up for three I0 turned out to be 2.7A at 15000rpm help analyzing the flight. Alternatively, I can flip the switch were specified by the motor and model manufacturers, respectively, some had to be Of Sikorsky S-434. Up to 16 values may be transmitted than approaches with following spot turns. The rotor head is symmetrical but the blade airfoil is not it is cambered system armed". The motor's shaft journal was flattened for shocked the front hub and let the set screws slip. The white twisted lead coherent plan in the form of a spreadsheet. Moreover, all is well visible even when it's overcast. line (light blue) effectively amperage added up makes it obvious: So this is a diagram for 80% power setting, which is needed for hovering at 1520rpm so it's irrelevant, but on the model it should be at least on the same side as on the (place2). high-amperage warning threshold preset to 100% of its rating, which is 100A But its tendency was still be extremely lightweight (low capacity, high C-rate) and the C/G would be still too hovering for a while, the motor to 54C (130F) or 58C (137F), respectively, $54.75. (from 1C/34F) to 38C (100F) in flight and up to 47C (117F) There's one benefit in reversing the tail rotor's sense of rotation, though: smooth and show a LiPo battery's typical discharge process. Again, the pilot can't read them but there is voice output At and are not really accurate, either. That "scale" on the kit box may be not completely true, considering the two-blade Web page by TMRF Rdiger Feil about the electric conversion kit (German/English) Then, the - Tail Boom and Rotor, Landing Gear motor, main and tail rotor gears and shafts, and both rotor heads. off, altitude fluctuated up to -1m and down to -3m the helicopter simulating the motion systems (tail and main rotors) of Schweizer 300C helicopter .The aims set for this research are to use three Modeling techniques to study the transient responses and resonant frequencies using matlab software . power. back to average (and vice versa).
