I have had the Walkera 60, 4#1, lots of 5#4, and two 5#10, the 5#4 was the best at actual flying, very forgiving and strong. They all have faults. I sold the 60 and the 4#1 because I could not control them when flying. I have had one Eflight heli and that would only fly properly if I removed the plastic canopy. I once turned the TX off before turning of the RX on, before I could do anything the Little Eflight took off straight up at full throttle and eventually landed with a loud noise and promptly disintegrated into a pile of bits.
I prefer the Walkera, they are improving.
