An OS .46 FX is perfect for this plane and most other .40 size high wing trainers. While the Rascal really isn't listed as a trainer, it flies and lands very docile. As long as you have someone with experience helping you (as you should with any first plane) you'll be fine. That plane with the .46FX will fly very nice at about 1/3 throttle. The nice thing about the .46FX is that you can most likely move into your next plane as well.
