    I know yesterday was forecast for severe mountain waves in scotland and personally i wouldnt have flown :D but i have flown in moderate to severe turbulence, I usually slow down and tighten the seat belts and put the Propellor into manual, then its the case of riding it out, but other than a slight shudder when you get a updraft with negative G i find the Europa excellent in rough air in comparison to spam cans, Read this topic online here: http://forums.matronics.com/viewtopic.php?p=480984#480984

    In my early days in my mono I hit some severe turbulence related to Welsh mountains. Fortunately my straps were tight or else my head or the canopy might have been the worse for wear. However when I came to put the gear down the lever stopped about 1/2" from the detent. Clearly the inertial forces on the undercarriage had forced a shift in the three bolt join with the gear lever. In the end I managed to get it into the detent by pulling like h++l with my right hand and thumping that hand with my left whilst flying with my knees. Otherwise I was going to land simply holding the lever back once throttle closed, hoping that the gear was overcentre and not about to snatch the lever out of my hand. Morals: 1.Beware rota in mountain lea in high wind conditions. 2. Drill out bolt holes to give a tight fit and bond that joint when initially fixing it.

    Colombia is mountainous and the trades blow 15/30 kt 350 days a year. As a consequence it's always bumpy. HJ460 handles this without any drama. Incidentally it feels quite dramatic but my dynon G meter has never registered over 2 G. On sunday I landed with 18kt right X wind (for some reason I prefer L X wind) which made me quite tense but down in one piece and in reasonable style.

    1;12 for my mono with wide blade Woodcomp prop, which will not stop windmilling even with engine switched off.
