Ed,
= Do you have the standard or outback gear?
The= standard gear has a distinct advantage with respect to speed limitations.&= nbsp;
The original Outback Gear added a lot of surf= ace area and a lot of camber to the doors.  Also, the two-piece design= cantilevered much of the area of the outboard door out beyond the attach p= oint.  This door is the week link.  A handful have failed in flig= ht and departed the aircraft.  The outboard doors flex quite a bit und= er aerodynamic loads.
On the other hand, I found the= the outback inner gear door can withstand the full 200 KTAS crui= se speed - even when detached from the actuator.  I had a rod end bear= ing fail back at about 150 hours.  I was pleasantly surprised to see the door remained on the aircraft.  -The rod en= d bearings have been replaced with stronger units made of a better alloy-
Back to door speeds.....
I am = now flying with a three-piece outback gear door set-up.  Like wit= h the standard gear the center door is attached to a new trailing link on&n= bsp;the main gear.  These door effectively have no speed limit.  = The only caution then becomes the gusto with which the gear locks into plac= e.  I have gone as high as 160 KIAS for extension speed. 
The impetus for these doors was not to increase gear = speeds, but to keep them from flexing open in flight and turning into = air brakes.

On recent trip in my new (50 hr.) = 360, a misadjustment prevented my left inner gear door closing.  I ele= cted to continue and gradually increased speed, seemed the faster I went th= e smoother it got.  Finished trip (900 mi.) at 200 mph.  No appar= ent damage to the door.  Query=E2=80=94at what speeds do gear doors de= part?  I have used 135 mph as max gear down speed=E2=80=94Now thinking= 160 might be ok if needed to get down quick.  Anyone know the answer?=
 
Getting out of front hinge canopy with a parachute?&= nbsp; I haven=E2=80=99t tried it, but my guess is you would need to get inv= erted and slow way down to push it open.  If rides about 2 inches open= if opened in flight.  Don=E2=80=99t try to close it in flight unless you have a go= od pull strap and on autopilot.
 
Finally, has anyone g= otten a Dynon Skyview autopilot tuned for vertical hold without hunting?&nb= sp; If so please send me your settings.  Ed Gray    Dal= las
