@jk3tjn The trim settings will remain even after you power off the drone but sometimes it needs an adjustment every so often.

@akihiro It looks like the email notification didn't reach you but the replacement battery packs have been sent and they are on their way!

@jk3tjn If the values are too low, you may not be noticing a significant change. I normally use 10-20, which solves the drifting issues. Could you describe the behavior you are experiencing (drifting forward, backward, left, right) and which values you are using inside of drone.set_trim()?

@alancox We do not have a new link because as far as we know Codebender has updated its interface and it was no longer compatible with our product. If your school has made it work, could you post those instructions to this thread? I think it would be really helpful for the forum community.

Regardless of the platform (Arduino or Codebender), the lessons on Basecamp will apply to both. The only difference will be in the setup which we don't have documentation for. You will need to reference Codebender's documentation for setting up a device.

@Akihiro Thanks for letting us know! We will be responding to your email with information for receiving a new battery pack.

@mercerdrones After the call with our team, we will able to get some replacements for you.

@mercerdrones This was a mistake on our part. We will be updating the documentation shortly! We are always updating our documentation and open to feedback to make coding education easy and accessible for everyone.

@mercerdrones We apologize for the misinformation. These are the maximum range specifications we received from the drone manufacturer but the environment can affect the range as well. If you need larger and more reliable range for your case, one option would be using the drone with Blockly. It may produce better results because it uses the computer's internal BLE instead of the board. Another option would be using CoDrone Mini, which uses radio frequency as opposed to Bluetooth. Again, thank you for bringing this to our attention and I will have our team look into it and update our documentation!

@mercerdrones We have found that sometimes in big classroom situations the Bluetooth performance will drop if you have more than 10 drones in the air. If you are experiencing multiple drops, reducing the number of drones flying in the air may help alleviate the issue!

@mercerdrones Thanks for bringing this to our attention! Someone on our team will take a look and we will let you know once the documentation is updated. An alternative way to calibrate can be found here.
