I am guessing that inductive loads(i your case are 4 motors) are intrudcing a lot of ripple or noise to your battery and 5v requirement is not completely being built up for atmega 328p so i recommend you to use a 5 v boost convertor for atmega328p and 3.3v ldo to get enough of 5 volts and IP5310 based boost converor would be perfect application for your case as it also includes charging protocol for li-ion battery.

If weight were the main problem, then it would spool up and not move. Yours is spinning in a circle, indicating one or more of the props are spinning in the wrong direction OR the rpm of the props is significantly off either due to malfunctioning motors or the controller is doing it on purpose for some reason. Also I'm sure you know those small DC motors are only designed to spin in one direction, yes? The wire colors indicate if it is a clockwise or counterclockwise motor.

Weight is the main problem. It has more but that makes the drone not to fly. It spins in a circle because: since it won¡t lift, the PID gets bigger and bigger on one side. Motors are spinning in the good direction and propellers as well. I will have to try bigger propellers and less weight. Thanks!

Electronoobs I disagree with your assessment. If the controller were operating properly, it would spin the motors at the required rate to achieve the target yaw rate. If you're NOT telling it to yaw, but it IS anyways, there's a controller problem OR the motors are not responding in the way the controller expects them to. It seems you have a yaw control problem as well as too much weight. Either way, I hope you figure it out, this is a great project!

If the geared motors have more lift, why not make some solderpads on each corner of the drone to solder a short length of metal rod and then attach the geared parts to that. This way you have more lift and you can have a heavier drone itself.

I think your biggest problem here is that the motors vibration affect your gyro/accel readings. You have no soft separation between MPU module and motors. You didn't have such a big problem with the bigger drone because it had long wooden arms that were damping the motors' vibrations. But with this tiny solid frame the vibrations hugely affect the gyro and your stabilization algorithm goes crazy causing the drone to jump and spin. You can see that most brushed frames have some sort of rubber dampeners for the motors.

The radiomodule can consume up to 350 mA, as i remember. So maybe voltage regulator causes problems because it's not powerfull enough. Motors are creating a lot of electrical niose. Also they provide feedback voltage when PWM signal goes low. This may cause arduino to reset itself. Instead of puting big capacitor on arduino power supply try to put small capacitors and diods between contaacts of each motor. Capacitors will reduce the noise and diodes will protect arduino from feedback voltage. Also it is aa good practice to put small capacitors on battery output and output of voltaage regulator. Thanks for the video. I've been waiting for it!)

Cool video. 1) There looks like a lot of circuit board real estate that is not being used. How about reducing the weight by cutting out most of the center of the board? 2) The board is wide in the area of the propellers. The propellers are working to blow on the board, where energy is lost by a change of direction. And there is probably with a bit of turbulence. How about making the for arms on separate boards that solder onto the main board? Or, have no main board, but just two boards attached as a cross shape. Question: You awesomely used solder paste to attach the processor. Why didn't you solder all the passive components the same way. Your killing me Smalls. :)

Replace the "arms" with wooden sticks just for testing to reduce weight. Also a bigger battery (and especially higher C rating one) will actually make it fly with more power, since I doubt a 150mah battery can push enough amps. Maybe thats the problem? I have small motors with 65mm props ant when I connect it to a battery they push a lot of air, no problem getting 60g of drone into the air. So a simple solution, make longer "arms" for bigger propellers and use a bigger battery.

One thing you could do is remove some material from your circuit board. That is one great big hunk of copper and phenolic and you probably don't need all of it. Maybe add some holes along the struts and towards the middle to drop some weight. Another thing might be to rework your circuit so that more of the heavy stuff is toward the center for better balance. Finally, if you're designing your own board, add the components for your add-on modules and get rid of the extra weight from those pcbs.

As what I can see from the video is that the front side of the drone is that where nrf24l01 is soldered. According to that the black propeller at front right must rotate in anticlockwise direction. Similarly all the propellers are moving in apposite direction. Change the direction of propeller and it will definitely fly.

Try Increasing prop size. I recently built a plane and it would not stay in the air, but I knew the motors could produce enough thrust because they had come from a helicopter that weighed more than my plane and the helicopter was capable of vertical takeoff. I eventually determined that it was because my props were too small so even at max rpm they couldn't product enough thrust. Increasing my props from 38mm to 55mm fixed the problem.

So why exactly are you using those small props? Are the motors maxing out with bigger ones and without a gearbox? If you chose the props just for geometry, try a tri-blade with about the same size. Or similar props with a steeper pitch. Other than that, the nrf24 module is great, but a pain in the butt when it comes to powering it. It doesn't like to be underpowered, but overpowering it might kill it. Ask me how I know :D Anywayz, thanks for the video, these projects that 'almost work' can become quite frustrating... Edit: The center part of the PCB does not look too tightly packed. I think you can save quite a bit of weight there in the next revision.

Oh and a few tips: I recommend you not to remove the ground plane, it protects the signal traces from rf interferences, but you can remove A LOT of PCB, the PCB is WAY too big for that little drone, also, reducing the size of the arms is a good idea just leave the absolute necessary space for the traces and let less mass of thrust to be blocked by the motor , I would the transistor and the diode into the PCB body not on the arms so they don't create so much inertia. Also for stability purposes, The acc/gyro chip needs to be at the center of mass as exactly as possible that's more important than put the uC in the center. Have a great day :D

I think hot glue might be a bit too heavy aswell, and if you make the next PCB a bit bigger maybe you can fit bigger propellers on, maybe with more pitch too (then you're back at the gear problem though). Also a 2S LiPo should give you a bit more power, just make sure your motors and other components are fine with the higher voltage.

You definitely need to improve soldering. My advice is never use lead free solder, use flux - a lot of, conversely. It is almost imposible to do good hand soldering with lead free solder. Especially for begginers. Start with 1206 instead of 0805 packages. Put small amount of flux on the pcb pad, heat the pad with the clean tip of soldering iron and then add small amount of lead solder. Use solder of 0,5-0,6 mm in diametr. Than place the component to the pad, hold it with fine tweezers. Heat again the same pad together with the component lead. Now is the component fixed to the place. Add flux to other component leads and pads and solder them one by one. You need to clean the hot tip of the soldering iron regularly. It's better to use short chisel type of the iron tip then longer sharp one. Check out some Louis Rossmann video maybe. And finally 10uF cap between Vcc and Gnd on NRF24 module is a must.Tantal is the best. And the small version of NRF24 not working together with the regular one. Good luck.

That would be a very important fix because a LiPo goes anywhere between 4.2V (fully charged) down to 3V (when you want to cut off to prevent overdischarging). Driving the radio from the LiPo directly is a great way to destroy it (or rather to drastically shorten its life, it may not fail outright), the voltage spec for the nRF2401A is 1.9-3.6V only. If you want to save a regulator and only drop down the voltage to a safe level you could use a diode with Vf of about 0.5-0.7V. However, the regulator also ensures the radio has a "clean" power, without the various noise and current spikes from the MCU and the motors.

Have you tried to block with a 47u tantal and 100n next to the radio module and mcu? Maybe an rc filter can help blocking spikes from locations, that have no chance to work with them. Are there bigger propellers available? The spinning direction is false. Opposite propellers have to spin in same direction, because they have to cancel out the rotating drift of the drone with a force through the weigt center of the drone.

(3.3v is barely enough for some - motors still supplied by the battery of course). Smaller "wings" to the motors is also better. hell even make a cutout for the nrf module since you are using modules make them as small as possible. Using the 1mm/0.6mm pcb should also help with weight but lower rigidity. - Nevermind saw the end of the video and you came to the same conclusions. Almost

If one propeller is rotating CW for example it should blow air in the direction of the ground. And if I make that the other motor rotates CCW it means that the propeller will blow air upwards. So if 2 forces blow air in a direction and the other 2 forces blow air in the other direction the drone cannot fly. How can i fix this?

In my opinion, the problem is that you need to put some trimmer to the base of the transistors to regulate the voltage for the four motors, it's clear in the video that the motor down the black propeller are spinning slower, if you want to keep the ideal pid parameters equals then you need a hardware offset correction or do you have this in your code? Also you need a powerfull stabilizer not just a capacitor, like a step down converter like this www.amazon.it/gp/product/B01MQGMOKI/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1 or a step up converter if needed. I said this because if you have a switch and all motors are connected directly to the battery you can try it, it should go up without pid or things like this, just because the motors with the same input voltage spin at the same speed.

The PCB is just too heavy to use as a frame and those propellers are too small. Try 4 mm carbon fiber rods or tubes as these obstruct the air flow less than flat arms. If you need a even smaller control system it is possible to shrink that ATmega circuit even more. Flysky receivers are much smaller and lighter than that nrf24 module. In such a small craft, even a couple of grams is many percent of the total weight.

What did you use for controlling the motors? Some specific motor-controller or just transistors/mosfets and PWM? If so, which mosfets did you use? As far as I can tell, those motors has a stall maximum current of 2A, so I guess any transistors that can handle up to 2A should work fine? Thanks!

to end the problem of restarting < put a resistor at each out put of the motors and it will not restart K it happened with me

so limit the current that goes to the motors?

, right , reduce current that goes to the gates of the transistors of motors , which makes voltage sudden drop at start up i tried to put a capacitor like you did but i had a little bet bigger motors so some times it worked well and some times not , so the resistors were the best solution

i think that the gates of the mosfets don;t have high resistance at start up ......

I have on my improvements list to add a 100 res between Atmega chip pins and MOSFET gates
