I can't speak for your specific drone, but I have experience with electronics and cold weather. I would definitely store the batteries in the warm, and check the manufacturer's guidelines for the correct storage voltage (for a LiPo I think this is about 30% to 40% charge, or 3.85 volts per cell) It also doesn't hurt to store them in a fireproof container ...

It should be possible so long as the aircraft has enough spare thrust and lift to counteract the drag and weight. Many model aircraft have good power-to-weight compared to their full size equivalent. For the banner attachment, you need a secure point to attach it to the aircraft, well away from any propellers or control surfaces. Usually this is on the ...

Probably the easiest way to get started building planes these days is with foam board models, such as those popularised by FliteTest. Foam board is a 5mm thick non-beaded polystyrene foam sheet with a layer of paper on either side for added strength. You can buy sheets from craft stores for a dollar or two. It's easy to cut with a sharp knife (small box ...

Okay, as someone who has just recently passed through this stage, here's my take on it. Almost all of the considerations below stem from the maxim that the best drone for you is one that you will fly the most. Both progression and enjoyment in this hobby (and many other hobbies as well) are directly linked to how much time you spend doing it. Whenever you're ...

When choosing an FPV camera, there are several things that you need to look out for: Sensor Technology Most modern FPV cameras use a CMOS sensor. These are digital sensors that generally tend to have a higher resolution (measured in TVL or TeleVision Lines) than the alternative, which is CCD analogue sensors. Pretty much every modern FPV camera uses CMOS ...

There are multiple ways to enable servos in BetaFlight, but since you need only one servo it is recommended to use SERVO_TILT. For servo to work you need a free pin on your board and this pin must have timer function. Go to Configuration tab in Betaflight Configurator and enable SERVO_TILT and hit "Save and Reboot" Then setup the switch you want to use on ...

There are several factors that are important for what FPV goggles are right for you: Type The first thing you’ll notice is that there are two main types of FPV goggles: slimline and box. Slimline goggles are usually more expensive, but they are also lighter and many people find them to be more comfortable. Their screens are also smaller, which means that ...

A four-digit number (e.g. 2212) This number describes the dimensions of the stator inside the motor. The first two digits are the diameter (in mm) and the second two digits are the height (again, in mm.) A Kv number (already explained on this site) Kv - or Kv - has some really good answers at the provided link so I won't go into detail here, but it is ...

According to electronics-notes.com, the mating cycle rating for the SMA/RP-SMA connector is 500 cycles. However, it is important to note that this rating assumes that the connection and disconnection process happens as smoothly as possible, with the body of the connector not moving at all while the screw connection is tightened sufficiently to not allow the ...

It is definitely possible to attach a banner to an RC plane. There are many people who have done it and It should be relatively simple. Some things to consider are: Use a very lightweight material for the banner. Make sure you have some support on the banner that prevents it from crumpling vertically. (you can use straws, a wire, or any lightweight rods) ...

An important first step to take when getting into drones is learning to fly them. The very first drone I would recommend to someone is a cheap drone that can be used to learn to fly. It can be disheartening to buy an expensive drone only to crash it and have lost hundreds or thousands of dollars which is why learning to fly with a cheap drone first is a good ...

I'd watch out for several factors: 1. Weight Drop any additional weight that you don't absolutely need for functioning. This may mean downsizing to smaller motors, which obviously means that you have to balance weight vs. power; you may be able to get your flight time much longer but at the expense of speed. 2. Battery Obviously the more juice you got, the ...

They are very different. Brushed motors Brushed motors are good for toy grade drones for a couple of reasons: they are cheaper and don’t require ESCs, which would add extra cost and complexity. Brushless motors However, in almost every way brushless motors are better: they produce much more power, are more efficient, produce more torque and, my favourite ...

So this method will vary based on whether they are brushed or brushless motors. For brushed: Spin the propeller with your fingers - is anything actively resisting the motion? If yes, remove the prop and check for something not immediately visible, like a hair or carpet fibres caught around the motor shaft. Remove anything you find and try the prop again. ...

There is actually no such thing as a 6-axis gyro; the correct term for this is "IMU", which stands for "Inertial Measurement Unit". An IMU is a device that combines several inertial sensors that measure the craft's orientation and position in space. The 6-axis IMU is a composite sensor, which contains two different types of 3-axis sensors on one chip. ...

It's not superior, it's just good enough, cheap enough and may be more noise resistant than ICM20602. There's a bunch of flight controllers with dual IMUs onboard. For example, Lumenier Lux F7 has MPU6000 and ICM20602, you can choose which one to use. SP Racing F7 and H7 series use two ICM20602s fused together. Also, there's BrainFPV Radix which uses ...

There has been a good deal of discussion on this topic, and it has been no small source of conflict between several of the main firmware players in the high-performance DIY drone flight controller world. The short version is that based on evidence gathered from flight recorder logs, the ICM series gyros are more sensitive to electrical and mechanical noise ...

Without disassembling the motor, and figuring out how the ESC is designed, there is no other way then simply testing it. From my experience, the motors spinning clockwise has usually been the ones that can be wired without crossing any wires and without having to reverse the direction. But that could just be a coincidence, so you should definitely not trust ...

I recently started flying myself (Approximately once a week over the past few months) and can recommend a flying wing made out of foam (Expanded Polystyrene (EPP)) with an electric pusher prop and a field with tallish grass (You'll also need around 3 tubes of epoxy, 2 extra propellers, a ladder and/or a pool scoop and in sever cases an axe ;) ). Model ...

It looks like you are missing a piece of the prop adapter. There should be three pieces, the nut, the central shaft with a thread for the nut on one end and a taper on the other, and a collar that matches the taper. You're missing the collar. The nut forces the collar onto the taper, which squeezes the slots together, gripping the shaft. They're normally ...

If enough current flows and two ground pads are far enough apart, there might be a voltage difference between them because of the resistance in the PCB:s traces. That's called a ground loop. As for why that causes noise; if the camera and the VTX have different reference points, a signal sent from the camera won't be received correctly by the VTX, and since ...

You may need new batteries. When a LiPo battery fully discharges, thin whiskers of lithium metal form between the plates of the battery. Attempting to recharge the battery will cause these whiskers to overheat, which may cause the battery to catch fire or explode. Commercial batteries from reputable manufacturers have self-monitoring circuitry that will ...

There are quite a few aspects of FPV, so a I’ll give a summary here. I’ll try to be concise so if any extra info is required or wanted, please let me know. The first thing to look at when you’re flying FPV is the kind of aircraft, all the way up from a small Tiny Whoop to an X class (please not for beginners though!). In general, the larger props tend to ...

The first step to getting the right propellers is to figure out what size propellers will fit your drone. What you can do is measure the distance from the center of the motor to the closest thing (probably the frame) that would block the propeller. Multiply that by two, and a few millimeters smaller than that is the maximum prop size/diameter. (smaller props ...

The normal blheli startup tones are similar to beep beep beep... boop. boop The first 3 beeps are the ESC's powering on and initializing then there's a pause followed by two more beeps which means the throttle signal has been received. https://youtu.be/_hkzm8ZXsxE?t=58

I think most people just copy other builds, and step up a size if they burn out any ESCs. If you want to be more scientific you could test one motor with a watt-meter to measure the current draw. Throttle up slowly so you can watch the current build, to protect the ESC you're using for the test. Also check the motor temperature after 30 seconds or so. This ...

If you're up for it, the fix you're looking for is to repair the connector with a new housing and new crimps (if the current ones are broken). Joshua Bardwell has an excellent YouTube video documenting how to do this, but I'll summarize here. Most LiPo balance leads are terminated with the JST-XH connector: (cit.) In the above picture, the balance lead ...

Good question. Brushed motors are generally thin silver cylinders with a shaft that look like this: Photo source: https://oscarliang.com/fpv-micro-quad-beef-board/ Brushless motors, however, will generally have visible copper windings and, most often, have the outside or ‘bell’ rotate: Photo source: https://www.hobby-wing.com/emax-lite-spec-ls2207-2400kv-...

As a general rule-of-thumb, brushed motors usually have two wires, while brushless motors generally have three. Image source

The Rush cable is slightly non-standard as it lacks the threads on the holes that the TBS connectors have. It works fine though. The SMA is a standard SMA thread, so the normal hole size for SMA connectors works well. In my designs I usually use a 6.5mm hole for SMA, though some of that depends on the tolerances you're dealing with on your machining. The ...
