P-12 payware

You sky kings that have the p-12 ---when you start it up, mine is set so if i have the throttle closed like normal well this little beast and also the Kodiak Quest which have the same engines shell 'go into reverse trust, so before i use it as i always and i mean always start my sim with the default Cessna then go to what ever plane i choose to fly. So i set my throttle ---precision flight controls- about an inch up off the stops, so when she starts she don't back up .Just wondering if any body else has this problem. Also the brakes are real fiece, the brake scolar is set to 1.25 and i don't want to play with it cause i don't know what i'm doing so does the brake scalar setting have any bearing on how the brakes respond? Might as well post here cause i always get a smart and accurate answer here Thanks
