Quotethe Nunchuck has Li-Po battery built-in along with UHF transmitter (google CC1070 chip) buffered w/ BFG198 trunsistor, tested range about 4-5km, on the flying wing installed modified Uniden GMR325 FRS radio, wing airframe weight under 200gram, now I have video transmitter added to fly FPV.

4-5KM with a 36" (at the max, as it looks). !! is that FPV as well ? I guess even 400mts is enough to loose orientation with this flywing.

Apparently he has a way to hand over control between different Nunchucks, or combine the input from multiple controllers 

Quotemultiple pilots can control one RC airplane,
commands combined , to let others control the plane simply center the ale/elev stick, ideal way to train new pilots or to double FPV tange while pilots miles apart, one at start point and other pilot at destination .
