Paul I have no photos at present but have installed mine on the P1 foot well with the Ignition regulator both in an insulated lightweight box unsealed to the firewall to allow circulating cooling air to escape. I have a 1" dia. Hose picking up intake air from well in front of the radiator with a little permanent position flap "catching" air to the box. I do not have the "gills" open (left them closed since it has been established that they were a development item providing little cooling benefit on shut down(positioned too low) and are now a "leftover" item.) I took some crude temperature tests early days and in flight they were generally less than 30 deg but on shutdown without top cowl service doors closed they never reach more than 37deg approx. Obviously opening the doors immediately defrays the cowling heat quicker as does parking into wind.

I'll be interested to see how the flight testing goes. The first picture with the flaps deployed seems to show two very large vortex generators (i.e the fairings attached to the flaps). I wonder how the aircraft will behave at high angles of attack and whether you will get increased turbulence on the tailplanes?

Hi Phil, I seem to recall that your field is aerodynamics, so I take your post very seriously...the last thing I would want is to disturb the airflow over the tailplanes. Would you care to elaborate? I've pondered at length over just how the flap deployment is accommodated while minimizing the overall width of the fuselage so that when the wings are detached, they can be stowed on the monowheel trailer. There are, of course, a variety of ways to cut the upper and lower fairings and vary the amount of fairing which deploys with the flaps.

In this somewhat (OK, more than somewhat) cluttered image, the servo is just to the left of the SCAT tube. Note the black outline drawn on the firewall to indicate the instrument panel molding features. The red tape on the servo is holding some loose components in place. In order to facilitate this mounting location I fabricated an aluminum bracket; the plan view is shown in the attached pdf file. The bracket was made from a piece of aluminum channel (with one leg removed) since an appropriate angle 90 degree shape was not conveniently available. Other stock would also be suitable.

I mounted my rotax regulator there and wish I had considered mounting the servo there as well.No hose or box needed. I mounted the servo per the manual on the tunnel where it is hard to get at and I made a box cover to keep instrument wires clear.

Note the detail pixs of the underside and flap. He has been flying for a number of years and has not reported any untoward events or disturbing flight characteristics. He believes his fairings have enhanced his speed and fuel economy.

I installed McFarlane's throttle and mixture controls in my "normal" airplane at annual and their quality is superb. The $150 spent on one of these is cheaper than the hair transplants that are necessary after rolling your own. http://tinyurl.com/dualRotaxThrottleCtrl D ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message europa-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Europa-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/europa-list Browse Digests http://www.matronics.com/digest/europa-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
