From KAVAN RC Wiki

Once trimmed out you can try your first hi-start with your DARA using 25–50 m towline (a fishing line). You can purchase a towline set in your local model hobby shop or you can make your own from scratch. Get a towline (any fishing line strong enough to hold 5 kg fish is OK), tie a key ring to one end (bowline knot is the best) and a flag (a piece of red cloth) 20–30 cm from the end. The flag makes the towline visible in the air as well as on the ground. Find a suitable spool to keep the towline on.
