I'm doing some research on my Europa with Jabiru 3300 to try and improve both economy and performance. 

Currently my A/C does 118kias at 2850RPM burning 27 litres per hour.  (at sea level)

I think it can be leaned out a bit to improve the economy but we haven't tried yet.

What are people's thoughts on fitting a VP Prop like Airmaster 332?  I'm wondering if this would help to either improve the cruise speed, or achieve the same speed with a lower RPM… and achieve a shorter takeoff run too.

Am I barking up the wrong tree?

Carl, no answer for your question regarding prop, but I know Bud Yerly has been working on a constant speed propeller for the Jabiru engine.  You might drop him a line.

I just started to fly my Europa with the Jabiru engine.  I sure hope I get better than 27 liter per hour.  That will kill me money wise.  I have had three short flights and have had to land quickly on each.  The first two were because of overheating.  The third flight I think I have the heating partially  taken care of as the engine didn't over heat, but the elevator control did not feel right so I landed.

Hi AirEuropa,



I believe my carb needs some tuning to improve the economy, I hope so

anyway!



I will be very interested to hear what you do to solve your overheating

problem.  What was the ambient temperature?  My aircraft behaves fine with

the temperature at 20 degrees C, but at 25 degrees C it is very marginal,

getting hot at only 1200ft.



I'm in the south of the UKŠ. So it doesn't go above 20 degrees very often!



(Sorry about the metricŠ !)



Regards,

-Carl.
