Last days I have made first flights with my Maxi. There are several things I'm chasing like small vibration in vertical tail fin, adjusting gain etc. But to be honest I have expected more stability from this ship. I don't know is it my thumbs, my setup or I'm expecting too much. I just can't get it trimmed. Even after i set dual rated to 70% and with 40% expo, it is not stable like my Raptor 50 was. I can control it, but even small wind came, it is rolling to one side and start to climb. All controls are smooth, no interactions on the swash. The only thing I have found is significant play in flybar: When i hold head i can move flybar 5mm left-right (in the direction of rotation). But I think that this could not affect stability. Am I wrong? Anyway, I have ordered few sets of flybar weights and FAI paddles. I'm shure It will help a little. Here are few photos from today:

I see you are using a FMA IR sensor and i would assuming the Spartan AP2000i, i have read a few reports saying that with the stabilizer it was causing some wierd control issues on the joker. Im not sure if thats the case in your situation but maybe worth checking out.

More likely though its the paddles you're using. When i first got my joker it was very twitchy, and the first thing i did was loose the stock flybar paddels, even with the weights in them the heli is still overly sensitive. I put on raptor 90 black paddels and she really tamed down. also i set my swash mix to be 35% 35% 35% for all 3 mixes and that helped a lot as well.

I hope that helps a little
