If other's have missed the thread Kmot started about swapping out the Saito engine modeled by dhk79 for the HP engine my father had in his Elder.
Per Kmot's suggestion I did model a completely accurate HP engine and installed it in the Elder. Aside from the name change and cs name change the new EA is identical to the original file except for the visual change of the engine (and some moveable pods in conjunction with the throttle motion)
