    • Spare parts, motor

      One of the wires to a motor broke off. Is there a place where I can order spare motors? I looked on the main site for spare parts and accessories but there's no motors for the CoDrone Mini.

      Also, what are the specs for the motors?

    • RE: hovering stability

      Did anyone get a solution to this problem? Here's my code in its entirety. I cannot get this drone to just hover in place. I don't mind the slight drifts, but the drift is huge making the coding exercise untrustworthy (though the code is correct, the students think the code is written incorrectly).

      Notice how I issue reset_trim() before a set_trim(). I tried this out of desperation to see if that would help stabilize the drone.

      import CoDrone_mini
      import time
      
      drone = CoDrone_mini.CoDrone()
      drone.pair()
      
      drone.reset_trim()
      drone.set_trim(-10, -10)
      time.sleep(2)
      
      drone.takeoff()
      drone.hover(1)
      drone.land()
      
      drone.close()

    • RE: hovering stability

      @jk3tjn I am having the same issue too. I have to always set_trim() to get the drone to hover in place.

      I just realized this thread is a duplicate of what someone else already posted. Please close this thread if needed.

    • Stabilizing the drone

      How do we stabilize the drone? According to the lessons, you can "trim" the drone using the remote or programmatically using the set_trim() function. The documentation/lessons also says, once you trim, you do not have to do it again and the trim you applied will persist on the drone until reset.

      I cannot seem to stabilize the drone and it does not seem like the trim settings persist. Here is the code I am using. Since the drone is drifting right, I use -10 for the roll, and since the drone is drifting forward, I use -10 for the pitch: drone.set_trim(-10, -10). This statement seems to be countering the right drift but not the forward one. Any ideas on why this is happening?

      import CoDrone_mini
      import time
      
      drone = CoDrone_mini.CoDrone()
      drone.pair()
      
      drone.set_trim(-10, -10)
      time.sleep(2)
      
      drone.takeoff()
      drone.hover(1)
      drone.land()
      
      drone.close()
      

      Now, after I set the trim programmatically, when I apply the program as above (commenting out the trim lines), the drone still does not stay in place (not stationary). Is there a video showing if anyone got the drone to simply take off, over, stay stationary and land?

      I'm wondering if the drone will always kinda drift.

      I am thinking the "trimming" is the "calibration" on the drone so that it stays put when it's up. Or is calibration another thing we need to do?

    • Will a 3.7V 220mAh 35C battery be compatible with the CoDrone Mini?

      There's a lot of great deals for the LiPo batteries 3.7V 220mAh 35C online. Will these be compatible with the CoDrone Mini? The original battery that comes with the CoDrone Mini is 3.7V 220mAh 30C.

      If a 3.7V 220mAh 35C battery is compatible, what are the consequences? Will there be heating issues?

    • RE: Is the remote defective?

      @robolink_leila said in Is the remote defective?:

      this lesson

      Thank you. That worked! The lesson helped with the visual on indicating what was the power button. On the controller, there are grooves to indicate what is what, but it would have been nice if there were contrasts (dark symbols) against the yellow buttons.

    • Is the remote defective?

      I just got my CoDrone mini. When I put in 2 AAA batteries into the remote, it does not light up. I thought maybe screwing the screw in would close a circuit and get the remote to light up; however, that doesn't work either.

      The only way to get the remote to power up is if I plug the USB cable into the drone from a computer. After which, the remote powers up and the drone stops blinking and has a solid light to indicate a connection.

      I swapped in other AAA batteries, but the remote just won't power up without a USB-powered connection. Any ideas?
