INDP51,
Your turbine sounds fine and appears to be running great, I wouldn't adjust anything except maybe moving the accelleration delay back up to 6-8. The smaller turbines have a much higher pitch sound when running at higher RPM'S than the bigger turbines. The growl sound you hear is normal when you have the accel delay so aggressive. Its ok to leave it, if that is the throttle response you are looking for. We have these turbines setup & test ran from the factory so all you have to do is install and fly!! (very little adjustments needed) If you insist on adjusting the parameters please write down the original settings so you can put them back to factory settings when you need to. You can also contact myself or Barry with any questions or set up help you need, anytime.
