The Europa Classic is not brilliant when it comes to cooling due to the design feature of having the oil cooler mounted behind the left hand coolant radiator and I have carried out all the recommended mods suggested by other Europa owners to improve cooling. These have helped and but now the weather is getting warmer (21 degrees!) I have discovered things have taken a turn for the worse. My last three flights have been a nightmare due to soaring oil temperature. For example, yesterday I started my take off roll with an oil temp of 80C and had to reduce power and level off after less than two minutes (1300 ft) with the oil temp approaching 130C and CHT of 120C. Cruising at that level quickly drops the CHT to 110C but the oil takes an age to fall below 120C. If I can get the aircraft into the cruise above 2500ft the temps stabilise at just below 110C Oil and 100C CHT, the problem is I just cant get that high at the moment. I have not changed anything on the aircraft so I am assuming it must be an engine problem. The oil level is always correct and I use Aeroshell Sport Plus 4 and Rotax filters. The oil has done less than 20 hours and I use MOGAS with no ethanol. Oil pressure is OK and is about 2.8 3 Bar at a normal cruise. Does anyone have any ideas what could possibly be causing this problem? I really hope so as I am not going anywhere as things stand!

Then I modified the lower cowling with the new location for the oil cooler under the propellor. It slides in from the inside when the cowling is attached and is thus isolated from engine vibration. This was all done during the build and we don't have the the problems with certification.
