Dear all



Thanks for useful info about fuel smell and landing distance.



The next question relates to changing the Europa Classic engine from 

Rotax 912UL to Rotax 912ULS. It is currently fitted with Warpdrive 

ground adjustable 3 blade prop. Can the same prop be used with the 

912ULS? Is there a noticable improvement in take-off and landing 

performance with this combination. What about the Airmaster prop 

conversion to VP using the existing blades?

I have placed a wanted ad on AFORS

William,



I can't comment directly on the 912ULS, but my 914 is a noticeably better performer with the Airmaster C/S prop.  I installed a ground adjustable Warp Drive prop for a couple flights.  It worked well enough but not like the Airmaster.  It was set up for takeoff performance (maybe a bit under-pitched even).  Acceleration, takeoff distance and initial climb were comparable to the Airmaster.  But cruise speed was only about 115-120 kts.  The Airmaster would get me about 140 kts cruise.  With the G/A prop you get either good takeoff performance and loose speed and economy or good speed and economy with less takeoff performance.  Or you can go compromise.  But you can't get the best takeoff AND cruise performance as you can with a C/S prop.  But the C/S prop is heavier, more complex and a lot more expensive.  So, you pays your money and takes your chances.
