Guys, me & Joel have joined forces to come up with a few treats for you in regards to Ground roll environment for the NGX.A bit later on today this is where it will all happen in regards instructions and downloads. We are both aware there are already 2 posts about this as that was a mistake because i started out then starting talking to Joel who has done a great Touchdown sound as we know this can be found here .. http://forum.avsim.n...ffect-download/As far as the taxi roll and RW takeoff bumps go we are both working on finishing this tonight and having it ready for you guys to try.This will consist of two files that will be provided and have full instructions on where to place them. Baring in mind to always back up your originals FIRST! You will have a taxi sound that ticks over while your taxiing. then on the main runway you will start to hear a much louder sound kick in at around 70 knots which will give the impression of cockpit shake & rattle on take off this is being tested as we speak & is working. These sounds include mine from Joel's.** I've just dropped the speed brake sound a few dB's a lot deeper now.. We will both keep you posted. We both done this as a realism feature not because we think PMDG missed it out !! Regards Steve & Joel.
