shaking in flight

i have downloaded two air flies for the AlphaSim/VirtAvia flankers and the shake in flight at a certain speed. I have no idea about solving the problem, but i have AirWrench. Can someone who has AirWrench help me ?
 
First off see what the Vne setting is in both the aircraft.cfg ([Reference Speeds]) & .air file - block 316 Mmo, but then also the Vmo in the Block 1100, then try increasing it.

I looked for it in AirWrench and in AirEd which I downloaded as well. But i can't find the reference speeds in either editor. can anyone tell me where the reference speed is at in either program?
 
The VMO and MMO are contained in the .cfg file.... The VMO is expressed in Knots, Indicated airspeed. I expect that the shaking does not however come from this area. What speed range is it shaking at?

To me it sounds a bit fundemental. If as you say you have Airwrench, I would enter all the facts listed in the aircraft.cfg file, then get a printout and compare the values with those currently listed. It could be as simple as a set of wrong MoI values, but very difficult to pinpoint otherwise.
Sorry not much help I'm afraid.

p.s.
You could try redownloading it & re installing just in case there has been a glitch somewhere!

BoeingvsAirbusNK, if you do'nt know then possibly you do'nt have it and your shake is caused by something else.

It sounds as if you have downloaded two air flies for the AlphaSim/VirtAvia flankers that are not AlphaSim/VirtAvia default do the work without shaking with the default files.

I don't think i use it.
 
Just a thought: if its shaking at 190 with a stall speed of 170, is it happening because of the stick shaker setting?

Some sort of high AOA instability, if you are using AirWrench, look at the stability sliders for pitch and roll and the stall charchteristics.
