Did a quick test during easter. Mounted my FPV equipment on a 1/10-scale RC car and had some fun. Lots of fun!
This was roughly what I saw in the goggles. (No, not that quality, this is a HD recording from the GoPro on the car.)
FPV is “first person view”. The art of mounting a camera and a video transmitter on remote controlled equipment. Then you sit down with some video goggles and the remote control. And drive the car based on the video feed. It gives you an amazing feeling of sitting inside the vehicle you are controlling. Like a video game. But in real life.
Fun when controlling RC planes and helicopters. But also fun (and much safer) when controlling RC cars!
If you want to snap images or record video from your quadcopter it needs to be as vibration free as possible. When you manage that you get shots like these:
But when you start googling you get the same answer all over:
1. Balance your propellers
2. Balance your motors
But I did that:
And I still had vibrations, blurry stills and jelly-looking video. After a lot of trial and error found the solution.
It doesn’t matter how much you balance your props if they’re the wrong props. You need high quality very stiff props for aerial photography (AP). So, on the same quad, with perfectly balanced props I had lots of vibrations with one set of props and no vibrations with another.
I have had best results with Gaui props and Graupner E-props.
In addition to this I made a dampening system. First I tried to mount the camera directly on a small plate that was mounted on the quad with rubber dampers. That din’t work very well:
(Dampers = red)
Then I made a long extra board under the quad. Mounted it to the quad using four rubber dampeners and mounted both the camera and the battery on that one. Wow! No vibrations with any of my cameras!
(Dampers = red)
And this is how video looks like if you don’t limit the vibrations.
