Is it a new engine? If so just try the 28-10 for now. And then use the 25-12 3-blade if you want after the break in, are you running pipes? If so try the 3-blade.

Hello, I have this plane with the 106CS too, with the 28/10 Mejzlik my plane is a rocket. My engine pull it at 6700-6800 rpm on the ground. I am waiting the new 3W L70 canister because my actual Muffler are KS 80V4 and they are too small (Vibration, no smooth throttle). During the first fly, i also have flutting problem on the elevator, my problem comes from the Kavan ball link. I replace it by the Dubro and now is good Julien |

Today I made an reinforced of the fuselage with 3mm honeycomb from the end of the canopy to the first former that it is placed in front of the stabs , this former was damage from the flutter. I think the back of the fuselage is too weak . I hope , tomorrow i will have more luck . |

I had some flutter in my Krill as well. I put about 1.5oz of weight in the counter balance of the elevator and have not had any issues at all with flutter since. I went with 1.5oz of weight because I had 3oz of stick on weight to get my cg where I wanted it, and so I used the same amount of weight to use on my counterbalances. Hope your flutter ends!
