In this flight I'm testing new antennas, both in the Taranis and the XSR receiver, it went well but I have to admit I was feeling apprehensive of going so far. Max distance reached at 04:20
Details:
-QAV210 mini quad
-Temperature 11C
-Humidity 89%
-TP-LINK 8dB antenna on TX
-Encased Sleeved dipoles on XSR receiver
-Spironet 13dB patch on goggles and standard CP Aomway (diversity)
This is very good, on subsequent flights I pushed it by flying behind trees and obstacles, there is a significant improvement in the radio link indeed, didn't get ANY alarms at all. RSSI was very steady even at 1klm away. The RX antennas upgrade is so simple yet so effective!
