I have some enclosed airframes and the interior can get quite warm when they’re sitting on the ground in the sun, causing the IMU temps to exceed the heater target (60C, in my case). Is there a recommendation for a maximum IMU temperature where it may become unsafe to fly if it is exceeded?
If needed, force cool the cube. Use a fan in your avionics bay. Or use a peltier, and a fan.
Do not mount the fan to the cube.
You should aim at a temperature of no more than 50 for the outside of the cube, less is better.
You don’t want the sensors going over 80 ever…

If the fan is just creating some airflow, no. If the fan is moving air from different compartments, and it allows a pressure build up to occur, then yes.
Hey @philip, just wanted to reach out and see if recommendations have changed since this post was made. I’m currently investigating a use case where external air temperatures reach about 52 C, and reported IMU temps are reaching up to 75 C. Current CubePilot specifications indicate a maximum operating temperature of 55 C. Can you confirm?
That’s maximum Air temperature
We recommend you operate the heater set to 60degrees
Try not to let the heater go over 80
