RE: Fly Eagle Jet F-14 Crash (video)
I doubt that very much..
Once you move the CG location forward, even if it`s not in ok balance, you also improve flutter velocity indeed.
At a perfect balance, the flutter speed will be higher than the engine can take the model (depends on MAC).
A nose heavy elevator pushes the limit even further. I`ll give you an example..
What is the optimum way to discover flutter? It is to have a very loose binding to the thing that holds it in place, agree?.
Like holding it in you hand.. 45 km/h was all it took unbalanced. If you took the same elevator and tested it on the fuselage, the speed would be significantly higher. And add a strong digital servo to force it to be still, we climb even higher in speed to have flutter, but we may get there. That is the way you know it.
Thats why the flutter come so suddenly, it creates enough power to finally get the freedom it strives for, because its held in place with a snug fit, "no slop" in the pivot tube /bearings (not speaking linkage to servo, that comes as an addition because we are without servo here).
Then we take the same elevator which I in my case fluttered in 45 Km/h before, now WITH balance..
In my hand at 150 Km/m down the 2000 meter runway, it`s just floating at ease, no tendensies to flutter.
And we move this balanced elevator back to the airframe without any servo, we get a even higher velocity before flutter, perhaps 250-300 km/h, and that`s before it fluttered in the first place at 150 Km/h. THEN we attach a strong digital servo to it, where do you think we are heading now..?
The plane can`t fly that fast...other things will come off first, like ailerons or flutter in r/stabs or rudder, wing-flutter, you name it..
Gaula River, here I come!
