FPV Quadcopter – first flights Translated from Russian
In this text, we will talk about preparing the FPV for self-assembly flights. Quadcopters Although some theses are applicable to any rc flying model it is assumed that you have already acquired the original motor skill in a computer simulator. Apart from the obvious fact that a real Model gets real damage, there are two critically underestimated novice pilots at risk:
1. Total loss of the model when she flew too far away and she is literally impossible to find
2. Damage to someone’s property or causing damage to my health someone.
The occurrence of any of the above events, in addition to the obvious consequences, can permanently deprive you of the chance to run the Model again and / or suffocate Enthusiasm for the business in all Fortunately, the work is not new. There are plenty of copies broken, and you have the opportunity to learn from it. strangers bugs.
Choosing a place to fly
Seemingly harmless average Quadcopter 5 inches Assembled from very hard materials, weigh the disease Half a kilogram and capable of speeds above 120 km / h in seconds. Its energy is enough to inflict severe injuries, break through glass. A car or reflect a dent in the body, inspire a stained-glass window of a cafe, etc. Even a slightly damaged lithium polymer battery can ignite on its own and cause a fire. The water battery does not infuriate due to the use of Nam Lithium Motors to spin the sharp propellers so the speed is measurable in thousands of revolutions in the second capable of leaving deep, cut and lacerated wounds. It must be understood that, unlike you, the majority of those around you are not even aware of these dangers. At the same time, in your field, when you are in glasses, limited by the field of view of the FPV camera, it is impossible to turn your head. Russia – Mother wide. Protect yourself from the consequences of the bride by choosing a place to fly away from people, animals and material goods
At first, you will often fall. To keep the same model, give preference to Locations with a soft cover to fall from a height of Paris tens of meters into the grass or tree crown, as a rule, does not cause significant damage to the quadcopter if you turn off the engines. Please note that it is difficult to find a model in the exit grass, and in the event of a stuck crown tree, uh, it will be necessary to somehow get it. Avoid dusty / sandy cover because. Sand gets into the motors already during the first takeoff and forms an abrasive mixture with the lubricant. bearings – wear occurs very quickly. In addition, sand can get stuck between the stator and the bell magnets provocative jamming snacks against the bell magnets to damage the windings. Mandatory model to fall Exactly There, this is the law of meanness.
You will need to navigate the terrain in order to deliver the model to the location. Landing, or online, where to look for it in a private drop. From above, this place looks different. For example, Flying high above my house you don’t see the color of Stan’s ego – only the roof If you fly Along the border of fields and forests you soon don’t even know how far it flew you Model (of course, Exactly at this moment you turn around Antenna
overlapped Housing model and lost connection). MOST similar Examples and recipe one
– choose a location with a good Definite Separately worthy Orientation and never fly out of this Location.
An example of a good choice of place for flying It seems a field with low grass, Several separately growing trees, bordering on one side with a forest, on the other A ditch with a strip of trees, on the other two Villagers of the road, one from which it is connected you with marrut to your house
settings that they usually remember too late
Failsafe is the ability of the model to respond to the loss of the control panel signal. when there is no navigation Sensors The algorithm should be something like this: wait 0.1 seconds Restore the connection, then turn off the engines. Understand how harmful the electronics are and make sure at home that the propellers are so removed (!) That the motors really turn off when the remote control is turned off. There were many cases when people ignored this setting, and when the signal was lost, the model simply did not change the last ones received from the command panel and flew away forever.
Set up the Beeper _ _ squeaker on a separate Tumblr of your remote control. If the Model is not equipped with a speaker, although most firmwares are capable of beeping motors, use This Option. You choose the key that you listen best to everything with an accounting sound environment The environment is usually good to hear the disease low frequency By neglecting the tweeter parameter, you doom yourself to eternal wandering through the sprouts of vegetation.
Turtle mode – “Turtle” mode. If it is included, you can rotate the quadrocopter motors. on the other side When using the right stick, the movement will start diagonally. corresponding motor (e.g. moving the stick up to the left will start the front left motor), Moving in one axis will start two motors at once (moving the stick straight down will start both rear motors). in the beginning the mode was meant for the riders to flip the top of the model’s foot, no going up to no It’s detrimental to the state of affairs of the model, but justified for the competition. You will appreciate this mode if (when) your model is hanging in the canopy of a tree. Usually the Quadcopter gets stuck one or two with propellers Turn on the blocking Motors cannot be used – they heat up to high temperatures very quickly, the varnish in the winding burns. A short circuit occurs and both the motor and the MOSFET in the speed controller burn out. just in turtle mode, you can swing the model, and it will relatively painlessly fall through the branches to your share on the ground. often this is better than climbing a tree, kicking fishing rods or waiting for a crane to start motors. you can confuse the position of the quadcopter in the crown and the launch blocked motors. Release stick no throw it The thrown stick makes several oscillations with a shift in the center position before freezing in the center.
up to what to fly
Make sure you fold my chair – no teasing the vestibular apparatus. You don’t. You will slow down at the speed of the ad description, and the movements of the joints will be more accurate if you are sitting. Use the neck cord for the remote control.
Remote control and goggles they are battery operated Who are you? they have the ability to run out of battery Check it in advance Your glasses should have a flash drive and not have to write a video of the flight sometimes only Thank you DVR record it worked to find daddy Model. The glasses are equipped with an optician who in the Back country gives concerts to the beams in Ponti. DO NOT ALLOW sun rays to fall into the lenses of glasses – Monitor matrices burn out changeably!
From the point of view of the Turtel in the mode, you imagined that the blocked motor was a burnt motor. Therefore, learn to muscle memory the movement of the toggle switch that turns off the motor (ARM). be always ready now to react and flick that tumblr typically you will take you about 2 seconds before they start burning engines.
In general, take as a rule in any incomprehensible situation immediately turn off the motors. If you don’t you understand what happens to the model if it’s gone video if it’s buggy Control… The damage from an out of control model with inline motors is statistically much higher. Also, while you are not in control of the model, it moves along an unpredictable traquerion remote from where you last successfully observed it.
Tighten the straps fastening the battery. Bolted connections Weight is the source of a lot of problems. In addition, a loose battery can fall out in flight. Separately Pay attention to the power supply and the balancing connector: they are not physically connected. reach Make propellers if this one no yes – negotiate a battery in other words, to sell a stretched Balancer it is possible to fasten a belt
To take off, place the model away from you and so that the wind blows away from you. Propellers You don’t need to attach anything. Use a folding table or special platform if necessary. In the absence of these, it is possible to adapt handy tools (backpack, cap and pebbles, inverted junk…) You will be ready for takeoff – you will be able to locate your model on the ground. over and over the sound of her.
Go!
Psychologically, we always want to start so stable original position, safe and comfortable to step forward from a hard surface, yes to say But! Air currents constantly carry the flying model to the side, and vertically too. Not only is the viewing angle in the glasses limited, you have a more optimal camera angle for yourself, but rather, you don’t take it. Therefore, DO NOT TRY TO HANG! In general, the Drift will press the model in the grass, take it to the Key or the pepellers will slowly creep right up to your face. We started to take off – to take off We started the motors and for sure you will tell the gas model no further than 5 meters. Don’t give up the gas! When the model reaches a sufficient height, simply reduce the gas pressure slowly. until changes in altitude are noticeable. It’s not scary if you haven’t understood it yet Another meter. Jerky work on the gas leads to therefore that you do not have a foot on how the position of the ego needs to be corrected due to inertia
Immediately begin to assess the environment and note the habitual orientation. On It Try For a long time there is no blunt because. Wind I won’t take a break for you.
With a pitch (vertical axis of the right stick) tilt the model away from you, make sure that it starts moving forward. Probably, the model will start to lose altitude – add gas. Tyago tilted quadcopter can be divided into horizontal and vertical components. Aligning the quadcopter to the horizon, you decrease the horizontal component and you increase the vertical, and vice versa. So you can only control altitude with Throttle, but also with Pitch_
The higher you fly, the more time you have to react, but the stronger the impact. land in case of failure. At high altitude, a strong wind blows, and the terrain looks completely different. as with the earth – it is easy to get lost Search your own Optimal.
Don’t forget that the model isn’t just flying forward, it’s moving away from you! It is better to start maneuvering as soon as possible if you will make your first flights on
circle without significant distance from the place to shoot Train yourself to hold the height and turn Always get attached to I’m focused on settlements, every second flight think Tom Where is he? The quadcopter is relative to you.
Gradually begin to fly lower and lower. There is no higher, it seems and quickly. There comes a moment when you no longer learn anything. There are many interesting obstacles to taxi below _ Moreover, to grow at a small height, require the ability to hold the height – this will be honed
– The model will be perfect. Beware of high-growing small bots and iron stems, they are very poorly visible in the camera
The model has inertia. In the turn you can look at the new course, but the old man’s part of the speed vector will remain. It is very easy to fly “to the sidelines”, similar to drifting. limitation Camera view can play a bad joke. The exercise helps when you are less than 90 degrees to the right (road, ditch) and try to change course along this line so that he does not cross this. When turning sharply, the model slows down with a roll, a growth effect is created. lift Usually not critical, if it doesn’t work out, practice letting off some gas during the maneuver program.
In general, maneuver more often. When your fingers don’t move, you don’t learn anything but remove time and battery power. In addition, the model runs slower when rotated. move away from you, thank you in a straight line.
No fly away Far In case of fall when you take photo glasses you will know that the Model “No Left to go tree” and “No true country road”, but to and simple application of the direction to assume the line drawn from you Make the left and right border where Presumably dropped Model they form Sector search Minimum and Maximum distance from you to draw in This sector represents the ring that the model is in. The farther away from you was the model the moment the subject fell It’s harder to burn Sector search, and the square ring quite grow quadratic from Radius! on an area of 100×100 meters, the search may take some time.Even if you set up the pishchalka, it happens that when the battery connector falls out, it breaks.the belt and the battery itself flies out
Flying over reservoirs, you take the risk of going home without a model
First time technology can fit. Maybe because you communicate yourself with the model. The fact of losing altitude and approaching the planet causes panic. Landing is smoothly significant and provacha – it will provoke evening gas After flying to the vital place of landing, turn around sharply (do not throttle the model) and as soon as you turn off the inertia, turn off the motors. If you have not yet mastered the turn on the spot, then cut circles of a smaller radius. and speed Start early to no allow battery overruns Turn off speed This is more important than minimizing altitude. If you turn off the motors at a height of half a meter above the grass or soft ground, nothing critical will happen to the model.
Once you have arrived at making a dropped/grounded model, the first thing you should do is
– turn off the battery When this is found, there is no hitting the tumblr turning on the motors on the remote. you you won’t Expect It, but this Mandatory it will happen!
What to focus more on
Don’t expect 1 battery to be enough for you. Should be 4 pieces. No neglect storage mode _ _ otherwise they will not live long
stock up with propellers, (often they break during the learning process), 20 sets for the first time will be enough, there will be no more. It is also necessary to have a small supply of antennas. Jack, belt and buckles
If Rama allows – Fasten the battery to two belts. Just believe.
Remember to check all fasteners regularly. The quadcopter is prone to vibrations, the bolts can be unscrewed by yourself – a screwdriver and a blue thread lock will help with this. The sharp edges of the carbon are gradually cut off from them, and they also suffer from falls. If you leave these questions uncontrolled, you can fall into flight alone from the motors, or the antenna jumps out under the propeller. And if the battery jumps out under the propeller, you will never forget this day …
The first flight on a new quadrocopter is desirable to make no more than a minute. Then, as soon as possible, it is necessary to take the Model in Hands and touch the Motors. Warm or very warm – the norm, Hot, which does not hold the pachie – not the norm, google PIDs (pids). Unstable topic. Interrogative help is desirable from experienced modellers. Also note the sound of a flying quadcopter. If fluctuations are audible (rapid hormonal changes in motor splices) – probably the PID or filtering is not set up correctly. Less common but also a possible cause is if the Flight Controller is installed without vibration pads and the flight mount nut is not stretched. controller, it rattles from vibration.
