The second moment. There is a graphic image of the helmet and a list of the main characteristics.
As a result, the distance to the screen is 9 cm according to the documents. I will immediately give an annotation with the conclusions, I am writing a review for those who want to buy this particular helmet. I checked, it really is. First of all, I’m already a very grown-up boy and, as a result, I have reading glasses.
FXT Viper FPV Helmet
Our mail did its best, the corner is jammed But it fits perfectly over reading glasses. I decided to buy a helmet for the Hubsan 501S quadrocopter. There is a helmet neatly in the trunk, and a bag with accessories Inside the box there is a nice case with a carrying handle The helmet comes in a white box with a minimalist design. And when I focus with effort, the Fresnel lens interferes with me – I see it.
Most helmets with Fresnel lenses do not suit me, as I will not be able to focus due to the display being too close for me. After much deliberation, I decided to stop at the one described below. This is the only helmet I know of that can be worn comfortably with goggles. The system of plastic mirrors gives geometric trapezoidal distortion. I can certainly focus on the 9 cm this helmet offers, but I need to strain.
This helmet was created according to a different principle – here is a system of two mirrors. There are also disadvantages. And that’s enough for me. A comfortable focus point for me is 13-14 centimeters.
