The 915 is an excellent mod Im really enjoying it 
The modder has done a great job of matching it as close as possible to the RW airplane.
Vertigo is like an F-16 aha! Turbulence (the real plane which inspired Vertigos modder) really does have blistering performance. Patey said Turbulence can climb at 7000FPM. It can max out at 705km/h (380kt)
An article, some performance specs are at the bottom.
