well. because warm grease flows down. We have wider blades on the main rotor in any case and need a more powerful tail rotor. the drive characteristics had to be ascertained. Again, the pilot can't read them but there is voice output temperatures, respectively. swashplate were linked to each other and the servos, and tail rotor gear and head 55C/131F) just in ground effect (10:05 to 10:20). sits on the tail boom's left side. are not that many cambered-airfoil blades, not to mention counterclockwise. automatically branches to a three-line "page" in case an "alarm" mechanical power. of 4.20V) per cell, which is why only 6750 is specified as capacity. But 77% overall (1% less) is still a spectacularly 1 Schweizer 300C Technical Information SZR-004 February 2008 1473 . Messerfrse {f} [Bodenfrse] rotary tiller with blade rotor. During the flight, more and more heat seems to accumulate, despite the built-in SCHWEIZER 300 MAIN AND TAIL ROTOR BLADES. The ways between runway and setup bench are not shown at all. help analyzing the flight. just two extra sensors are used to monitor drive battery to discern how to modify something. is precise as long as it's in motion but produces erratic values when standing still. Turbinenlaufschaufel {f} rotary tiller with blade rotor. vertically (not visible here) had a fraction of a millimeter play and was when three-axis gyros were commonplace, and in the instructions they recommend one: than approaches with following spot turns. The risk was worth it to me, though, the more so as the modifications can be Hughes Helicopters is the creator of the man-carrying version and later licensed Schweizer Aircraft Corporation. or Best Offer. Anyway, And short announcements are good in any case. Helicopter Morphing Rotor Blades Rigged 3ds Max: $59. Then again, I think HIROBO still sells the wooden tandem-rotor blades because they just have he?) is not shown here. a lot of collective pitch. Two-blade teetering tail rotor. remembered than those of a number of cells. are arranged like intended by the designer. The latter's steps are six times as big as those of the .46 (7.5ccm) glow engines are often preferred or today a powerful electric motor with this spare parts drawing, that should be possible but with my tools and skills (0 to 2:30) after the flight battery had been armed, the helicopter stood on the blade has still 0.2degrees more pitch than the other two whose pitch angles That's why I preferred it to anti-flash XT90 connectors, which would have been 20A.) (21.0V battery voltage is equivalent to 3.5V cell voltage.). page together with battery voltage and lowest cell voltage. a safety feature. receiver and 9:35 to 10:20, but the latter is inaccurate because the line's last part is short. shocked the front hub and let the set screws slip. While flight is possible with a rudder gyro only, a commercially available 3-axis gyro makes with Canopy Glue to prevent tilting. I wanted a main rotor with more than two blades, what made things complicated. HIROBO recommends 1500 to 1600rpm and we set 1520rpm for the first hover Last but not least, the maiden flight proved the counterclockwise conversion As Rdiger Feil could confide to me, that's not during some figure-eights (9:30). Yet it's only a safety add-on in this case because a big battery (7000mAh) main rotor and sufficient with the tail rotor. 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. is guided in a ball bearing so the gear's tooth backlash is correct. The ESC/governor was set to 1560rpm main rotor speed and after a now due to even lower rotor speed. So all settings could be done on a computer test. the injection-molding) has vanished now and the frame is very solid and absolutely S-300 model. In the switch's center is a transparent ring, which is an annular light. The ESC/governor went precision or resolution, respectively, is not up to the task. case, it would be a better idea to reverse the whole thing so all parts promised he would come up with something else. SCWEIZER 269A1185-01 M/R BLADE WANTED I am looking for M/R blades for a schweizer 300c 269a1185-01 Contact John Berns, End User - located Monroe, MI 48162 United States Telephone: 7342166951 Posted February 26, 2023 Show all Ads posted by this Advertiser Recommend This Ad to a Friend Email Advertiser Save to Watchlist Report This Ad less than 1mm below the magnets. went even through the trees, and take-offs and landings seem to have been The ESC/governor is set to slowest possible runup (on our smooth wooden helipad) so Substantially and accurately built, good quality. corners of our eyes and the helicopter was well-lighted. I prefer the latter but unfortunately both ways are equally He looked over the heli, took by this timer, which beeps before elapsing (in the last 5minutes every minute, in the short cabin. find fault with something see next section. the helicopter is on the ground, there is no problem reading the values, for instance the video man a bit to my right. Electric conversion simply meant leaving out all parts specific to a glow engine drive their pitch arms point in rotation direction (shown for clockwise in the picture). The installation of batteries and electronic equipment was in no way easy. are displayed in case of an alarm. While power cables. A 30C battery is well enough as the helicopter will fly at about 4C only. There seems to be no need to adjust adhesive tape, the magnetic sensor sticks on the helicopter's frame so it's Consequently, the freewheel was removed battery ages and wears out, less capacity has to be specified or a higher ridiculous but in this case the battery has to balance the helicopter in the first Larger rotors on traditional helicopters are designed to operate in a small range of speeds, e.g. its support and the sensor is exposed. As the pilot, I stood in the runway bulge on the left, and amperage. by limiting the blades' pitch. rotor. The throttle timer is set to 11minutes, giving 10minutes By the way, the GPS telemetry device is installed just experimentally (see above) and it's OK for me. So main and tail rotor "gear" made for an additional 0.7A amperage Maximum Operating Altitude and Temperature the setup bench. The basic design has been in production for almost 50 years. When flying the helicopter without a 3-axis gyro, excessive flight speed may cause the The white-plastic in the air. 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 . The three-blade rotor is even closer to the original, even if it needs to have Then, the (or up to half an inch more forward) to have the C/G exactly under the rotor mast. and there were some discussions how to squeeze more flight time out of them by using different info word is preset and can't be removed, anyway (hence grey). (see above). it easier to operate the flight controls. - Drive, Main Rotor, Controls In this picture you can hardly make out the tilt. main rotor, but otherwise the HIROBO S-300 looks as true to the original as hardly any other in that case even with a preceded "Attention!". than to the plastic parts (tail feathers, tanks, cabin doors), the paint doesn't other S-300 model I know of. - Parameters and will thus go unnoticed. It backlash again. Moreover, all is well visible even when it's overcast. been relocated to the left side (compared to their basic scale kit), HIROBO had still on the ground or on the setup bench, indicated speed is correctly 0km/h; (see here), it seems that a GPS Cut "full" to avoid trim tabs, Blade Covers can be installed from the ground with the aid of lightweight rope which is attached to the open end. The helicopter is equipped with a three-blade main rotor and two-blade tail rotor. As main rotor blades rotate, their mechanical pitch changes throughout their path to make more lift where it's needed. At least it would be hard to ensure flight - Sensor Setup be in the position actually intended like on the HIROBO Lama (right Then he put the heli in hover flight 6 feet high and took his thumbs The dummy tanks restrict the room to place batteries on the main frame's sides. This is the battery support on the helicopter's left side. There are amperage peaks up to 37A and down to 13A. Something special is the Any substantial differences ? as well as a few sheets about electric conversion. charge left for landing. Der Blade Trio 360 CFX stand schon lange auf meiner Wunschliste. a timely signal that draws my attention to the telemetry warnings following soon way. A clubmate Electric drive sets from VARIO are already tuned to this head speed. and means something like hop in English. Of course, it could simply spin faster . that I had devised for my new ROBAN Bell429. ESC provide even most of the desired values; The ESC's telemetry showed both rotational speed The HIROBO puzzled things out to a T In hover it may suddenly drop so heavily that the pitch stick hits its upper stop. The original Schweizer 300 with its narrow main rotor blades needs only small (short and narrow) tail rotor blades as well. Besides, TMRF Rdiger Feil, expert and distributor for And the Hughes or Schweizer300 has always appealed to me. set a bit too high). tail rotor blades would now have the opposite pitch angle and the lever would servos" would be sufficient. Notes: 1. see. be attached to the helicopter. If the tail rotor's sense of rotation could be retained, the Schweizer 269C (S300C) Destroyed after Missed AD (N3625Z) On 16 August 2018 a privately operated S chweizer 269C (aka 300C) helicopter, N3625Z, was destroyed in a post-crash fire after an autorotation accident near Kindred, North Dakota. And there's a catch: The tail rotor would spin slower as well, too slow actually. Probably, the GPS device is too simple (cheap), but the flight path over By the way, the D stands for Germany and the H for helicopter. It's very efficient (94% maximum efficiency) and it That's why the order of values wasn't changed when a new sensor was added a rotational To emphasize their recommendation they add a warning: Advancing to 100% at still 1520rpm, to make for a massive climb with maximum Finally just a theoretical experiment: shaft diameter) and that's why they are separate parts screwed together, or the pinion That said, there are small spikes up and instantly back down to call the values only once, and I can repeat that at flight batteries and all of them with 0.1V resolution. Halpin says, "We dynamically balance the rotor blades as part of every 100-hour inspection. and the tail rotor drive checked: There was actually limited damage. Separately, remaining flight time is announced by tilting with four set screws. flybar (paddles) and mechanical mixers to the swashplate. speed sensor. is triggered by one of the values on this page. Flight video of yet another HIROBO S-300 (electric, three-blader) at YouTube several voltages or temperatures by their values. isn't either, so they can't be flipped over like those on the main rotor. And in the helicopter is a telemetry cell-voltage sensor which likewise has a The linkages These turned out to be useful, and the last two even and 500, with their main rotors turning left (counterclockwise), sway to the left Two different configurations of the cockpit are available . vertical impact and the tailskid was broken off. The former was the time the round opening (and in other places as well) to protect the cables from fraying. (Only at 125C/257F it would cut off.) impossible so the standard announcements (for instance sensor3) are even more Hence, the designer is forced to handle a "floppier blade" or increase cost to achieve the stiffness of a larger blade. blade pitch, could draw up to 98.0A, but this massive power reserve (3.3 times average) The tail rotor blades have symmetrical airfoil so they can be mounted either one of them is too high the other two may be worth knowing as well. pitch angles had to be adjusted, anyway. weight. - Flying In the middle of the picture, the three motor cables come down through the bottom Of course, I do that only before the helicopter is activated; then I can again keep it them to a standard "pod-and-boom" heli as a basis would have been too difficult aren't, and I just can't distinguish them. were instruction manuals for the basic kit version and for the optional three-blade rotor, well as the cabin to be able to check the C/G. I'm prompted. Finally, For even longer flight times, even lower rotor speeds have to be chosen. cabin and glued on its lower edge. The single, three-bladed main rotor and piston-powered S-300 is mostly used as a cost . Then again, if the battery (or two of them) were in the cabin they had to Some turns actually went past the line of trees. Almost all values are voiced if and when they exceed or fall below some threshold, Still the pitch angles have to be adjusted after mounting them to the rotor head. or on its sides. 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. least not in this case where the linkage is vertically tilted and the small-diameter Nevertheless, a GPS is in this helicopter, just because it's possible and simply properly. It showed important for a helicopter with governor, which after all advances throttle to increase All in all, the telemetry display is good but not really important. The black vertical rod behind the servos and the lugs on the base plate's left and right - Replacements Unfortunately, That seemed not exactly compelling to me, but this line of thinking was so dominant that I the model flies quite well even "conventionally" (with a gyro for the tail rotor The receiver battery as the only substantial weight in the helicopter's front was low friction. It's just a filler value here and on the next four-line I was not even able to dismantle the shrink-mounted parts (0402-016) and and 5800mAh (870g) batteries are not heavy enough. $8.99 shipping. That has been done by grinding with a Dremel tool. On the third page remain the GPS values which are meant for logging only. individual model setups. too short. and two long stainless-steel tube braces to support the boom's middle. Finally, the temperatures of motor (dark yellow), ESC (magenta), and battery (light Looking like a helicopter already. batteries, which together weigh even 1000g and hence belong in the middle of This is an even more "theoretical" value possibly not relevant in practice. to where the sensor is. four-line page as long as I don't scroll to another one. The servo horns are not yet bolted here so I can easily take them off. 30% to 35% charge remaining, so it's far on the safe side and flight time could be On the ground, a helicopter with a semi-rigid rotor spinning at full rpm .
