Will Will sorry, I was too brief again, (getting too lazy to type) The effective angle of attack imho is more dependant on the relationship between the center of the leading edge radius and the trailing edge than the bit in between. this can be anything between a flat plate and a thick ellipse and still have the same angle of attack. Lift is more or less linearly related to AoA in the cruise. This is when a built in roll will be most irritating. You will need roll trim, which is useful anyway to account for assymetrical loading.

I think that I was not being clear I meant mid wing span wise not cord wise but your clarification is useful to say the least. So the cord is the line/distance between the leading edge and the trailing edge so that in this instance the angle of incidence is cord 2.5 deg leading edge up relative to the datum line which is the left windowsill. The template is merely a method of measuring this - one could for example attach a straight edge to Leading edge and Trailing edge and achieve the same effect. So the next question is roll trim...I am assuming this is a servo embedded in the aileron connected to a trim tab in the ? right wing. Anyone have any advice on this type of servo etc?

Many have put it on the left so they can have a visual on it. But I think it should be on the right to that the smooth portion of the trim tab raises up into the airflow as opposed to the left wing where the linkage side of the trim tab lowers into the airflow. As for servo info, mine is an MAC S9 Trim System from Menzimer Aircraft for about $180. But their website has expired so you might want to check Aircraft Spruce for their RAC Electric Trim Servos. They look identical. There are also pix in the Europa Forum from those that have already done it. Good luck.

Took my third flight today and my oil temp after leveling out was running at 250 deg F. and head temp was 220 deg F. The weather is really bad around Florida right now. Today the temp was about 95 deg and around 100% humidity. Are these temps normal for this heat and humidity. Anyone running in this kind of weather that can give me their temps?

I think Tony Krzyzewski has tested a simple string attachment to the control-stick in order to trim. According to my memories it worked very well.

After we made our cowl mods, this same condition resulted in 220 deg F oil temp. See those 'engine compartment cooling' mods at; http://terryseaver.home.comcast.net/N135TD_mods.htm 2) Be aware that the standard Rotax oil temp sender location is at the coolest part of the oil system, right after the oil cooler. We added a thermocouple at the inlet to the oil tank, and measured temps 50 deg F higher in climb and 40 deg F higher in cruise, when compared to the 'standard' oil temp.

Once in cruise they settle down to somewhere around 90C. Suggest changing to Centigrade - sounds less alarming, and besides its progress!
