Using these Gemfan 2925 5 - Blade Propellers for your DJI Avata is easy. First, make sure your drone is turned off. Then, carefully remove the old propellers and replace them with these new ones, ensuring they're firmly attached. When flying, keep in mind that these propellers are more efficient and generate more thrust, so you might need to adjust your flying style a bit. For maintenance, after each flight, check the propellers for any signs of damage, like cracks or chips. If you find any, it's best to replace the propeller right away. To clean them, simply use a soft cloth and gently wipe off any dirt or debris. Store them in a cool, dry place to keep them in good condition.
