You are wrong. Not only will it help, it will stop it. The only reason you do not know that is you simply have never done it. I have, and I have done it not only with a wide variety of model aircraft that have actually demonstrated flutter in flight (I am and talking hard core flutter ya know that which not only sounds like a machine gun but it also visable).

These all were some of mine and other fellows particularly at the warbird races which were lucky to survive the first dramatic episodes.

Jaka the other contributing factors you mentioned are indeed contributing factors however its a far more complex problem and that is only a scratch on the surface. Flutter analysis is a entire aeronautical engineering discipline in itself in which whole careers are committed.

Jaka it may be of interest you to know that virtually all full scale aircraft use controls surfaces that do indeed feature mass balancing to some degree.

Now in addition Jaka it agine may interest you to know that back in the eighties when the Fun fly aeroshaft airplanes (these aircraft were the progenitors of the modern 3D types) became all the rage, that the hugh control surfaces combined with the rubberband like fuselages (aeroshaft), The aero elasticity became absurd and of course those airplanes would always flutter anytime full throttle was used other than a perfectly up vertical line.

It was during that time after I had suffered complete controll separations on at least six airplanes and that I started extensive tests with mass balance on a fun fly type, a published design called a Richochet, Not my design. These included balance all the way up to 100 percent of all surfaces and I repededly found that balance anywhere above 20 twenty percent in every case eliminated all trace of flutter and full power could be used in virtually all attitudes except straight down.

These results have also been evident with later types of airplanes that I have used the simple balances on also.

Jaka it works and works well at the speeds most of our flying is conducted and it works most dramatically For any airplane that has demonstrated and survived the onset of flutter where all else has failed. I can only surmise Jaka that you do not know that because you have never and won,t try it.
