goblin 500 and microbeast tail bounce
I am having slight tail bounce at low rpm hover and fast forward flight. I've tried increasing and decreasing the tail gain with no effect so far. Is there a setting in ar7200bx that i am missing that may help this?
specifics: hover bounce goes away at around 2200rpm and it is not a fast frequency bounce, maybe 2-3 times up/down per second. Then I only get it in FFF. -thanks |

Hi
Double check your COG I had the same issue but with a MSH BRAIN. COG and a little tweaking fixed it Good luck |

Sounds like dial 1 cyclic gain a little high.

I had that problem when I used the MB. Turning down pot 1 will fix it.

Pot 1 can go as high as about 10 o'clock on many of the 500s I've setup for people.
If you're getting the bounce and you're only at the 9 o'clock default then something is wrong. I found more than a few people that had not setup the servo frequencies for the swash servos and this makes a huge difference. Check your step B |
