Not that I fully understand what is good or bad but I assume that a sharp change of velocity is not so good. Is then all the blue around scoops and openings bad? So this weekend went to 9FL1 Fly-In breakfast with EU. Being the only Europa most people have ever seen it was always surrounded by people :) Nice flight. Great speeds (people making comments on the radio on how fast I was going for a 912 powered airplane). Grass runway, a bit bumpy, takeoff was interesting but all ok.

Sadly this year skiis only due to organiser-illness, so low passes on ly. AOA lectrical connections now appear to be solid, what a great tool to m anage energy over the runway. Luv my lil=99bird in the winter - great performance imho, ~135knot at less than 5gal/hr.

Are those pieces of cardboard at the radiators to help maintain engine temps? Chris, variations in colour indicate changes in airspeed velocity; there is a scale if you zoom in and the velocity applied is 51m/s or 100kt; low velocity is not necessarily a bad thing however its an indication of turbulence induced drag around exit vent openings and rearward of aft surfaces as slower and faster moving air rejoin, getting these two velocity streams to combine back together more smoothly is a desirable outcome... one of my test pilots has just suggested trying vortex generators; will be interesting to see if that has any desirable affect... will be interesting to see just how much total drag can be reduced and how that might be achieved!! For the technical minded the test was carried out with theta, beta and delta all set at zero, alpha is equal to angle of incidence. Returned output forces NM (x) -587 (y) +4424.
