Also known as "Harmonic Ressonance". Phenomenon that happens when the natural vibration frequencies of two or more components add to one another, causing a continous increase in vibration amplitude, which could destroy an airframe. |
The most common type of flutter found on R/C aircraft is Control Surface Flutter, which usually generates a flapping sound and can cause damage to a servo quickly. Flutter problems can be correted by changing any parameter of the frequency equation and it could be as easy as decreasing flight speed, or if a permanent solution is desired by changing the control linkage mechanism.
