RE: HK 450 pro question/help
Hi Bob,
Your problem is that the gain on the gyro is too high. I usually set the dial on the gyro gain to full CCW and adjust my channel 5 (Gyro Gain) to around 25 to start on rate mode, and 75 to start on Heading Hold mode.
If the tail wags slowly, then I increase the gain (decrease the number on rate mode, or increase the number on HH mode). Please keep in mind that channel 5 is sending a servo position to the gyro and center is neutral. The extents of travel of that servo would be Rate in one direction and HH in the other.
I still tend to get confused trying to get my head around that one.
