 Results:
Propellars no.1 have problems with noise and vibration especially when climbing.
It is not a very effecient propellar.

Propellar no.2  Jabiru Wood  prop. 2 blade 64*30 gives good performance but is like the no.1,
noisy and gives vibration in the cabin. ( cavitation ).
 

The propellar no.3 to 7  have the same problem as the no.1-2 with angle between 6.5 to 10 degrees
it changes rpm but not Flight data for cruise and climb speed.
Again not a very efficient prop.

Propellar no.8 is a prop. with special construction was very effective both on the Jabiru engine and
with  the Kitfox IV. There is no slip and no vibration in all conditions both on the ground or in the air.
Climb and cruise performance is very good and gives 85 mph at 2400 rpm,  and 90 mph at 2500 rpm.
Max. performance in level flight 2800 rpm and 100 mph.
