Fixing the Jello Effect on S800 EVO with a Zenmuse Z15 Gimbal

When I originally began flying quadcopters, it was mostly because I was interested in becoming proficient in aerial photography. After many, many hours of flying, I realized how much I really love flying quads and it has become a great hobby of mine.

As recommended by many, I first began flying with cheap, toy quadcopters, and eventually worked up the DJI S800 EVO. I have found this hexacopter to be even slightly steadier than past quads I have flown which makes for great aerial photography. To enhance my photography even further, I decided to attach a gimbal so I could control the camera more precisely and to enhance stabilization. Unfortunately in the beginning, my plan did not really work out as expected.

Once I installed my new quadcopter gimbal, the Zenmuse Z15, I started to experience extremely bad shaking that rendered any footage I recorded, unusable. The entire quadcopter gimbal and the batteries would wobble uncontrollably and you could see it in the videos. A few friends mentioned to me that it might help reduce the quadcopter vibration if I balanced the propellers and motors, since this was something I had never done before. Typically, any quadcopter vibrations that result from unbalanced props are high frequency and small but I figured it was worth a try.

After I finished balancing the props and motors, the quadcopter vibrations depleted slightly but they were in no way eliminated. I later found out that the large shaking was due to the tightness of the foldable propellers. The individual half of two of the propellers on my S800 were actually very firm to rotate. Thanks to my large group of friends that fly quads, we were able to collaborate and come up with a great fix.

When you are tightening the propellers on an S800 EVO is large quadcopter Review for Beginners , you need to be very accurate because of the folding device. You are going to need to carefully tighten the bolts that hold the propellers to about 4 NM pressure. This can be determined by using a torque wrench. The propellers should be allowed to find their own alignment due to centrifugal force. This won’t happen if the bolt is too loose or too tight which will lead to extra quadcopter vibrations. Once this tiny thing is fixed, vibrations should cease, allowing steady video and photography.
