ViperPilot2 Posted June 19, 2021 Share Posted June 19, 2021 Howdy! I've loaded a couple of Spitfires (AF Scrub Vb, Mk. XI) and the Aeroplane Heaven Hurricane into the Sim, and when I select any one of these to go flying, the airplane is shaking violently on the Runway with the brakes applied. Any ideas as to why this happens? Thanks!

mrzippy Posted June 19, 2021 Share Posted June 19, 2021 In the aircraft.cfg file, these are the settings you may need to adjust: empty_weight_pitch_MOI = 1600655 empty_weight_roll_MOI = 588050 empty_weight_yaw_MOI = 2148751 empty_weight_coupled_MOI = 0 Still thinking about a new flightsim only computer!

hjwalter Posted June 21, 2021 Share Posted June 21, 2021 Alan, Can you please supply download file names and from where you downloaded them, so that I can try your problem myself and report back in this thread. Regards Hans Link to comment Share on other sites More sharing options...

Regards Hans spitfire_mk11fs9.zip spit_mkvb_mkvctrop.zip spitfire_mk_vb.zip aihrcn04.zip All from the File Library here. Funny thing is... I choose each one to fly in the Sim last night, and no shakes on the Runway! :confused: Go figure...

ColR1948 Posted June 21, 2021 Share Posted June 21, 2021 I've had AI taxi OK then as soon as they takeoff they shake, and as Charlie advised I had to tweak them to correct it. I've had AI where the weight and balance is so bad they flip on the tarmac and vansh, then it's a bigger tweak lol. Col. Link to comment Share on other sites More sharing options...
ViperPilot2 Posted June 21, 2021 Author Share Posted June 21, 2021 I have a stinking suspicion that it's the Pilot, and not the Airplanes that are at fault. Maybe I just need to get better at flying Mr. Scrub's aircraft!
