FlySky micro receivers ground level range test

This is unscientific receivers range test, made at the ground level. My transmitter (Flysky FS-i6) was placed on the roof of the car and I went for a walk with 4 receivers.

Receivers that were used in this test:
8A Mini Receiver - https://goo.gl/arhMnr
Flysky FS-A8S - https://goo.gl/Eufv3L
FS82 - https://goo.gl/4PmmHY
FS-RX2A - https://goo.gl/QkuCQp

FS-RX2A started to loose signal at the 60-80 meters, FS82 had solid signal link up to the 400meters. At the 500 meter mark all the receivers were out of range except the 8A Mini Receiver!

The final results:
First place - 8A Mini Receiver - https://goo.gl/arhMnr
Second place - FS82 - https://goo.gl/4PmmHY
Third place - Flysky FS-A8S - https://goo.gl/Eufv3L
Last place - FS-RX2A - https://goo.gl/QkuCQp
Disclaimer: I have bougth all the receivers from my own money (except FS-A8S, that was received from Banggood for review). All the opinions and conclusions were uninfuenced by anybody.
