It happened to me three times. One time managed to recover, two times with some astronomical chance, it landed on some bush. I am not totally new to this, flying Electric for 10 years and slope soarers for 20, but I'm starting to think it might not be an advantage but a disadvantage. I like to go high to take good videos, than at one point I feel that it is time to come lower. No, I am not pulling the power all the way down, just to the middle. Then maybe my airplane experience kicks in because I would expect immediate response, but sometimes I feel like it is still going up. Because of my glider flying, I tend to think maybe I catched a thermal. As I keep on lowering the throttle, sometimes it wants to fall out of the sky. Lately, I am flying with carbon props, it is like cutting butter with a razor, now even easier to go high. Also adjusted the gain to 80% Sometimes, instead of trying to come down in one spot, I push the nose forward, but I can not do that all the time because that would put me above something I don't want to go. I think the ideal copter should not fall out of the sky, if I lower the throttle too much, it should come straight down but not tumble all over. Am I the only one to have this problem, am I missing something?
