I apologize for taking so long to respond. I appreciate the heads up on that. I have seen them fly but not flown one myself. I am leaning towards blade heli's cause of the cost and available parts around here.I've been dancing around on size though. Around here the wind blows 4 out of 7 days so mine has a hard time at times. I would like to fly outdoors sometimes after I get done with my cars and trucks.</p>
