We've always had a problem with the wakes in P3D ... they just are not realistic. I've found a program that really gives a nice wake. McCoy Water Effects, you can find it
here.
A "sister" to this program is the Goose Realism Fix, which changes the contact points. You can find that
HERE.
Attached, you can see the "new" wakes I can now achieve. The Piper float plane works without the contact point fix, just applying the McCoy makes it work.
Without the contact point fix, the Goose didn't work well at all, it needs to be lower in the water, then it works.
I tried it on the Aerosoft Beaver (Standard Wheels Model where all the action is) ... and I get nothing. But I have not "lowered" the aircraft by changing contact points. Perhaps someone here could give us some better contact points for it.
This little program set really makes things start working for wakes.
