Have any other Classic owners done this and, if so, would you be willing to let me have some details on how you achieved this? Also, the dreaded question. Would I have to classify this as a mod as far as the LAA were concerned? Finally I show below the text of my post on the Rotax forum. If anyone has any ideas I would be delighted to hear them! Aircraft: Europa Classic Tri Gear Engine : Rotax 912 UL (80HP) TT 440 hours Propeller: Airmaster I am having a major problem with excessive oil temperature. 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!

I mounted the cooler to the engine, centrally below the spinner arc which allows me to remove the cowling S without removing the cooler. I made a smiley face opening in the cowl and formed walls to duct the air straight to the cooler. This is not a 100% cure and excess climbing does require throttling back, but most normal climbs can be performed ok, and once levelled off my temps drop quite quickly and in the current 25 degrees I get very low 100s or even high 90s for the oil temps and CHTs at 90 Unfortunately this does fall within the requirements for a LAA Mod.

That was recommended by other builders who had brought the Rotax 912ULS 100hp engine which produces 8% more heat that the Rotax 912UL 80hp e ngine. I am surprised you have problems with the 80 hp motor and cooling as t hat was the original configuration and was proven. The 100hp came with a Fib erglass air shroud cover to be place over the engine to allow better flow of air for cooling. I therefore had to form a round inlet on the starboard sid e to allow air to enter for that shroud. This is what I did for the oil cooler; *With the engine cowlings still in place cut an inlet hole directly below an d central to the spinner the shape and size of the oil cooler. Rounded corne rs. *Take the engine cowlings off and with a piece of blue foam that came with t he aircraft shape the foam to form the inner walls of the inlet. The walls p rotrude inwards not outwards like a Spitfire nose as there is enough room be low the engine to fit the oil cooler vertically upright. *Fiberglass around the inlet foam with 3/4 layers of Bi-directional glass us ing Vaseline as a barrier on the foam to withdraw it after cure. Run the gla ss Bid well onto the cowling around the foam for attachment and strength. *Once cured withdraw the foam and apply Fiberglass with peel ply to the inle t inner surface to give a smooth result before filling and painting. *Cut the inlet protrusion to accommodate the oil cooler as far forward as p ossible to allow room for the oil cooler and space behind for air to escape. Make sure the cooler is vertically upright when in level flight. *Form a platform out of Fiberglass for the oil cooler to rest on and Fibergl ass it onto the bottom inner protrusion and cowling. Once cured drill a hole for the oil cooler metal protrusion to slot into at the correct position. *Make a similar small platform at the top left hand side (looking forward) f or the oil cooler connection to secure its position with the two bolts. So t hat the oil cooler can pop out when taking the bottom cowling off once the b olts are removed. When attaching the bottom cowling to the aircraft you have to place the oil cooler in position first and bolt it on then move cowling i nto position and attach. * Oil pipes run from the oil tank, left hand side of engine bay, to the oil c ooler underneath the port water radiator and then from the oil cooler, starb oard side under the starboard water radiator around in a loop back to the oi l inlet connection to the engine. I am overseas at present but I can send you some photos that will make it cl earer if required. It is an ideal modification which has already been done b y other builders in the UK namely Peter Kemper with his first Europa so it m ay well be already an authorised modification with the LAA. It looks good an d is streamlined with the "Classic Cowl" and is very effective with cooling , too effective at times. Rotax prefer higher temps. Better that way than the other. All the best.
