IFH has a McCauley constant speed prop fitted to an 0-360.
I don't expect a better top speed but the climb is certainly good. Watching the clip and measuring in google earth it seems as if the takeoff roll was about 240m!
The prop comes with a weight penalty. IFH is 617kg empty versus 580kg for GAB.
New canopy looks nicer but didn't really notice much difference in flight but was probably distracted!
IFH has a dynafocal mount and GAB has a conical. The dynafocal is definitely smoother.
Hope to fly again this weekend
