Engine choice
I ran an Irvine .46 for the first 100 flights then changed to the Irvine .53
Now will hover and "tork". Easy and as inexpensive as it gets. You alone decide what "plenty of power" means. I run an OS 91/4S in a UCD-3D and it is more to my liking (still fly the Pizazz) as it has more at low throttle settings (engine tork).
The Irvines have given great power and reliability.
