From: Richard Iddon I had exactly the same experoence. Cut out the opening, discovered I didn't need to then patched it up with epoxy/bid and filled and faired it. After a short while running, the heat from the exhaust made the patch turn brown and some blisters appeared. I refilled the blisters and resprayed the patch then stuck some aluminium foil over the patch inside the cowl to reflect the heat and haven't had any further problems since.

I still haven't' refitted the original, I'm not convinced that it's important, certainly had no problem rigging without it. Regards, -Carl. On 16/01/2012 08:59, "Martin Olliver" wrote: > >Hi Roland.

Hi Graeme, When I built my plane, I also cut out that inlet. It is still open after 10 years and 800 hours and I am not aware of any ill effects. I have never had any cooling problems and in the winter, I have to partially mask my oil and water coolers to maintain temperatures. I would suggest leaving it alone.

From: "graeme bird" Had a sudden panic that I had unnecessarily opened up the lower cowl starboard NACA duct and that it was only required for 914 inlet and not my 912. I cant see what its for for the 912ULS as it would only cool the oil tank (which is already too cool in flight) and possibly one end of the exhaust.

Well, in that case to make you aware of it: Diverting air, rushing by with a speed of 100+ knots, from a smooth path alongside the airplane, instead into a hole with lots of obstacles, sharp turns, etc and letting it out again as a turbulent mass in the wrong direction and with the wrong speed, is certainly costly in terms of performance and efficiency. And in this case for no usefull purpose. Maybe you have invested a lot of effort to make the airplane as smooth as possible, in that case such a needless source of drag is an even larger waste. As a general rule you should close off all unnessecary holes in an airplane. This is the reason why you have made the covers for the torque tube access holes. You can leave them off without any ill effects, except of course a reduction in speed and fuel efficiency.

Maintain temp on cold weather (on 912) Hi there All, Some collateral question about maintaining oil and cylinders temperatures during cold weather (I have ~70C when external temp is 0C): has anyone installed some mechanism to deviate fresh air from the radiators, as I have seen on other home built planes? Any REX?

Frans ________________________________ Message 9 _____________________________________ Time: 10:30:43 AM PST US From: "Sidsel & Svein Johnsen" Subject: Europa-List: Maintain temp on cold weather (on 912) Max, For the coolant cooler, I have fitted a shutter (controlled during flight from inside the cockpit) purchased from Vans Aircraft. See attached photo, where you will note that approx. 1/3 of the cooler front area is not covered by the shutter. This is to allow free air flow into the warm air collector behind the cooler, for heating the cockpit (in warm weather, this collector is open at the back). You will also note that the oil cooler is completely covered by aluminum plates in this winter photo. They are no longer used, as I have since fitted a Rotax recommended oil thermostat. This arrangement works very well for me (912 ULS), down to outside air temp of about - 5 degr C (I don't fly in colder weather!).
