0. Is the Gremsy series waterproof?

No. The system battery, motors, and other electronic equipments are not waterproof.

0. How many operation modes does the H3 have and how do I switch between the modes?

Gremsy H3 supports 3 types of operation: Normal, Suitcase and Inverted Operation.

  • The default operation is normal.
  • Switching to Suitcase from Normal operation: Make sure the gimbal is in LOCK mode (you must switch to LOCK mode if it’s currently in FOLLOW mode), then hold the left / right side handle and transform to Suitcase operation. Now you can switch to Follow mode normally if you like. To come back to Normal operation, let's do the same thing, make sure the gimbal is in LOCK mode before transforming to the operation you want.
  • Switching to Inverted from Suitcase operation: This is the same procedure with the case above. You should remember to put the gimbal in LOCK mode before transforming between Suitcase and Inverted operation.
  • Switching to Inverted from Normal operation and vice versa: You don’t need to power OFF the gimbal, you just need to turn OFF the motors, then transform the gimbal to the desired operation and turn ON the motors again.

The H3 has the same switching between operations like the H7. You can learn more at HERE.

Advanced Technical Question

0. What should I do when Roll axis has a drift during the flight?

You should refer to CANLINK for this issue. If you already installed Canlink but it still drifts, let’s take a look at your gimbal’s IMU. Firstly, do Gyro calibration, then use the red button to turn ON the motors without remote controller (remote receiver disconnected). If the roll level is off in this case, you should do Accelerometer calibration again, make sure the Tilt and Roll axes are in perfect level during calibration. In general, this solution will solve your problem and you can come to do CANLINK setting again. Otherwise, please call us via our skype ( , we will work with you for advanced support.
