Just bought a used Raptor to learn on. What should gyro settings be? The tx throttle is reversed, throttle up-stick down, throttle down-stick up? What are the tx base settings? I got the model with the brushless, and lipo, but it does not want to lift off at full throttle. Do I need to adjust something to get it off the ground? When I hold it in my hand and throttle to half I can feel the blades pushing air downward, as soon as I start to throttle more than half it seems to lose lift. this bird is tail heavy no matter how far forward I move the battery, is there a fix for this problem? Any help on any of these problems would be appreciated.
