I'd like to modify the roll rate of an aircraft. I had the 'Cessna Sport' from here at SimV and that had been modified to be faster and have a quicker roll rate so i know it is possible. If i could i would also like to modify it so that it could travel vertically at a higher speed/without stalling. I know this is un realistic but i just wanna have a little fun

Thanks for any help,
