Set up RCtimer 30A simon K ESCs in my Quad controlled by NAZA. When I arm the quad, it fires up suddenly at 50% throttle( Does not take off when i slowly increase the throttle) and doesn't increase until I hit the 50% mark on the throttle. The esc does not seems to have a throttle range that I can take off slowly - even though I've set the throttle range on each ESC. If i lower the throttle it just cuts early somehow and the craft will just free fall down. If I lower the motor idle speed to from the recommeded, the quad flies but does not stabilize. I'm using a Flysky TxRx. Anyone know what's going on here?
