RCT800 Video – FPV Camera Mount Testing

RCT800 FVP Camera Mount Testing (Also known as the last few videos and pictures I took with my Canon Digital Elf before it went swimming and never came back).

The brushless motors I bought from RCTimer (630KV) seem to have one fatal flaw; the motors are great in terms of performance but the prop mounts are poorly milled and or cast. They make it almost impossible to mount your props without causing an imbalance and vibration. This turns your sweet flying rig into a vibrating machine and makes good videography pretty tough (make that impossible… see the last clip) even if your props are balanced.

I’ve been testing various materials to deaden the vibrations and sponges from the dollar store seem to make great (cheap!!) vibration absorption material. In total, I tried rubber bands, paper, duct tape, string, a homemade shock, and two different sponges before coming to a solution. The homemade shock had some promise but it was outclassed by a simple cheap ($1) sponge so I didn’t take it further than a few quick tests.

As you can see from these two test videos the results for regular dollar store sponges were decent (compare these videos to the last one). I found that all I needed was a little bit of sponge between the camera and the aircraft’s hard surfaces. This almost completely eliminated the vibration from the props.

Got pretty high in this video… You can clearly see the river that I later had to wade into in order retrieve my Hexacopter after it went haywire and crashed.

These results are especially good if you consider the movies I was able to make earlier (before adding the sponge).

Here is a sample of those vibrations, as you can see the movie is unusable and a little sponge will absorb quite a lot of shake (the only real difference between the movies above and below is the camera mount sponge padding)
