Cons: Additional weight, long TX antenna etc. Pros: Roughly $150 dollar investment.
2. A better option, upgrade your TX receiver to Dragon Link V3. You can go up to 80 km. Dragon link V3 receiver will transmit back telemetry back to your transmitter and then transmitter forwards the telemetry to your GC (Mission planner) via blue tooth connected to your laptop.
