"Not Enough Force/ESC Error"

Current Worldwide Frequency

RareCommon

Severity: Low Risk

   Low severity, impact on safety is likely not significant

Description

This happens when the Electronic Speed Controller (ESC) is unable to provide enough power to the motors to either maintain hover position, or to fulfil climb/accelerate commands.

This is a common message and in most cases it just means that the drone works harder than normal. However, in a few isolated cases this was observed shortly before a crash.

Consider decreasing altitude and flying less aggressively. If the problem persists, land immediately.

Had this today and my drone crashed.

Firs i had this error "Motor error. Check propellers and fly with caution (Code: 120652)".
Then this "Aircraft max power load reached. Decrease altitude and fly with caution. If this issue persists, land immediately (Code: 30168)."

Tried to land but it wasn't responding, it was increasing altitude by itself and then it stopped and crashed.

The last error on the flight report notifications is "Not Enough Force/ESC Error"

Motor Speed Errors my come from damaged or wrong installed propellers. Try to replace the whole set and install new ones.

I also had the problem while flying in low temp situation with high humidity (fog). Because of the wind-chill-effect on the fast moving propellers, they're freezing on thousands of little ice crystals. The Drone trys to increase the motor speed to compensate the flow drop of the propellers airstream ... if the freezing is too strong and even the motor itself is affected by the freezing, Motor Blocking errors shows up on the Log (30165).

If the ESC can not compensate the insufficient Air Stream Power, the drone will stop motors and drop of the sky.

Then i suppose the "Low Risk" severity is not pretty accurate.

Experienced this error at 6F and 73% humidity. Resulted in the same behavior as @Alina. Had to fight to force a manual landing.

Thanks for the info Paul

Meu Mavic Air2 estava na praia de Pipa que tem ventos muito fortes, no Brasil. Na ida foi a 4000m de distância, comecei a voltar com 51% de bateria e na teoria deveria sobrar, pois fui com 25% de bateria. Mas a bateria começou a cair 10% a cada minuto e pousou na água sem forças no motor pra retornar, deu esse erro no histórico aqui do app.airdata: Not Enough Force/ESC Error 17 times. Caiu cerca de 1500m do ponto de decolagem

volando a la orilla del mar, el dron mavic 2 pro, dejo de responder y se apagaron los motores y cayo al agua y lo perdi, hoy uso por primera vez esta pagina app.airdata y me arroja este error (Not Enough Force/ESC Error) en el registro de vuelo. Dji debe avisar en su aplicacion este tipo de errores, yo perdi mi drone por esta falla tecnica y es un drone con apenas 6 horas de vuelo. dinero al agua

Same problem here. I never received the error notification while flying. It is only on checking the logs post crash, that I got to see the cause. DJI is liable for this one.

Hi
Just to share my story, DJI doesn't even care, doesn't accept litchi logs, so can't do nothing for me... like 500eu isn't nothing...
But: flying at a temperature around -9°C at night. Flying at eyeheight and a few meters distance, ready to land. But ...

The same on my Crash. Many times it happens . I change the escs and motors and it normalize . I`m Happy I do a hard test 500 meters altitude and cross clouds on the top of a 486 meters hill. I love the image and the result of the information that the AIRDATA gave to me. My crash I have to much luck, I go to visit some friends on a 11 floor of a buiding in Rio de Janeiro. The motor go with no force and came down rotating and drop on a tree and nothing happens I get him with stairs shut it down and on and flight again only for 2 meters above. And came home to see whats happen in here. Luck Guy (71 years old) kkkkkk

Had this error today and it acted exactly like Alina's comment below. I was hovering then suddenly it started to climb then I saw the camera go wild then disconnected error. Looking at the log and route the disconnect came after it crashed. Log also shows I gave it no control inputs. Since the Air was still connected it logged a spiral down to earth from over 200ft up hitting the ground at 80+mph. No more drone. Looks like one or more props failed mid air as I couldn't find any of the pieces.

Bonjour,
Meme incident avec un Mavic Pro 2 tout neuf. 1er vol le 17/04/2021. vol stationnaire à 110M de hauteur puis descente à 25m toujours en stationnaire puis chute brutale. Log AirData: Not Enough Force/ESC Error (repeated 8 times) + ensuite Barometer Dead in Air. Low severity, impact on safety is likely not significantNot Enough Force/ESC Error (repeated 16 times).
Je ne pense pas que ce soit un "risque faible". Résultat: un hélice cassée et retour SAV pour échange du drone. Un moindre mal...

I had an ESC error appear on. my screen for a split second and then went away. I’m not overly concerned but at the same time, it did happen once before a few months back. I still had a smooth flight and landed safely. I fly a Mavic Air 2.

I have a Mavic 2 Enterprise. This inconvenience just happened to me. I was flying at a distance of about 400m and at an altitude of 120m, when the message "IMU is initializing. Please do not move the aircraft until initialization is complete" appeared. Since this is not the first time I have seen this warning, I opted to leave the controls. It is at this time that the "ESC / Insufficient Force Error (repeated 23 times)" alert appeared. Then I lost control of the aircraft. It only glided, but it did not ascend or descend. Fortunately it was only 5 seconds. I took control of the aircraft again and landed to verify if it had not been damaged by a bird of prey, since I fly in an area where they are. The fuselage is in perfect condition, as are the propellers. The weather conditions are favorable, that is why I do not understand why this problem has happened. I hope to rule out some kind of technical failure.

Today it happened to me. Phantom 4 advance crashed into the sea... It was mooving on 16mph speed and then just fall... Logs say that the last warning was Not Enough Force/ESC Error

Lost my Mavic 2 Pro to this error a few days ago. I was at 115' 14 minutes into an automated Pix4D Capture flight when drone erratically went off course. As I was using Pix4D, I did not know the error. The logs reveal that it reported Not Enough Force/ESC, Exited GPS Mode, and attempted Auto Landing errors many times. It hit the ground with 47% battery reported and then started reporting Propeller Fell Off.

After a mission I landed the Phantom 4 advanced. And when I picked it out of the sky when hoovering, it shut down without warning. The battery went just off. later in the log I could see that cell 4 of the battery had a lot of deviation for a minute during the mission and that the battery temperature was 61degrees Celsius. Pretty sure the battery had shut itself down as a safety matter. Now the question is: Did this also happen with the other cases in the comments? And can I still thrust this battery? In a later flight everything was normal. A battery temperature warning would be helpful so I could land the drone in time. An other question is: Can these battery's be tested and analyzed by the dealer to check their health. they are expensive enough.

This code appeared when my Inspire 2's sweptback arm assembly became loose in flight after lowering the landing gear. The propellor struck the forward obstacle avoidance assembly breaking off half of the air foil and sending my Inspire 2 into spin. Fortunately the craft automatically switches into a "headless" mode that allowed me to safely land.

Experienced this after taking batteries out of winter storage.

I executed a short, less than 1m hover from a grassy area to pavement. After initial takeoff to execute initial performance test (directional changes, hover, etc) when I noticed "something" wrong and immediately landed.

The drone, an Inspire, would only begin to pirouette on its RF leg, when takeoff power applied. I shut off the aircraft, checked motor (RF), prop clearances, battery signals. All appeared clear. I carefully reattempted takeoff, followed by low level hover and slow maneuver for 10 minutes and completed over an hour of subsequent flight without incident.

Upon return and debrief I noted this error. I am contributing this comment in an effort to assist diagnosis of the overall issue.
