3D Prints

This weight of AOS CINE35 frame is 123 grams as you see in the picture to the right. It comes standard with M3/M2 steel screws and 25mm M3/M2 aluminum standoffs. M3 hardware is used for the main parts of the frame in the middles and M2 on the rings of the props guards.

Here I switched out all the M3 steel screws to titanium and reduced the weight by 4 grams. In the past, I would have switched out the M2 screws too, but it is not worth the cost, because the weight difference is barely noticeable.

I thought the 25mm standoff was taller than necessary, so I switched them out to 20mm. With that change I was able to reduce the weight to about 3g.

Here I gained some weight because I replaced the carbon fiber FPV camera mounting plates with a 3D printed version that has a custom vibration dampener on it. Because I am using a DJI O3 air unit, I want to reduce any unwanted vibration to the super sensitive gyro located in the FPV camera.

The Build

Two months later, I finally started to work on this build again. Everything went quickly because I removed all the electronics from the GEPRC Cinelog 35 and moved them to the new frame. For the most part, the only thing I had to do was extend the length of the wires for 2 motors.

Instead of using the caddx vista I will be switching to a DJI O3 air unit. To mount it to the frame, NewBeeDrone made it simple with their aluminum mount that lets you mount the air unit to a 20x20 holes.

Here you can see that I still have lot space even though I switched out the original 25mm standoff to 20mm. That is why I called this setup semi-slammed with the 5mm shorter stanoffs.

My initial intention was to use a GoPro 11 mini with a custom clam shell mount. But after doing a few tests, I felt it is not necessary to use a full GoPro. Plus, I already have a Naked GoPro 10 and Gopro Bones, why not use them so I can reduce the AUW to gain more flight time.

By switching to the GoPro bones, I would save around 80 grams because of the smaller camera mount and the camera.

Prop Testing

During the test flight I tried a lot of different props......

•  Gemfan D90MMX3
•  Gemfan D90MMX5
•  HQ D90MMX4       
•  HQ D90MMX5       
•  HQ 85MMX6        
•  HQ 89MMX8
•  iFlight Nazgul Cine 3535 3-Blade     

In the end, my favorite props are the HQ D90MMX5

This is still works in progress...
