The tail on Helios is very quick but a great flyer. I indeed like my V911's big time, but like flying Helios just a tad better. Each heli is different evn same make. That is part of the game and makes you a better flyer. I clean/ service/ and store them like a good machine. They [mico's] are a good learning tool for RC Rotor craft flying. I have a long road to go but well into getting experience for 6 ch C/P birds. I will allways have some micos for indoor fun.
