I've slightly miscalculated my battery on twinstar2. It is 2700 mAh battery, but for some reasons it became empty then OSD indicated 2100 mah. Maybe video link drained too much power, maybe the weather was slightly colder than usually. There is a chance that OSD was not calculating consumed power under low load.

I've tried to glide back home but there was not enough height. Anyway I've retrieved my plane in 15 minutes, because it was easy to understand landmarks. I've tried to land near the road. Even I can't say that's my 7km range record, because it didn't do a roudntrip, it was very valuable knowledge what the twinstar and my setup is capable of.

Setup:
Twinstar2, 8x4 props, 100ish g motors.
2700 mAh 3S1P Zippy 25-30C battery
Sunsky 500mW vtx + inverted vee antenna
Lawmate vrx + 11 dBi biquad 1280 Mhz antenna
ChainLink @ low 200mW power mode.
Smalltim OSD, modified for CL LRS
Fatshark cam
