Christisn,
I would not be too concerned about the nose gear.  Even a= t 200 kts it will only see a drag force on the order of 50 lb.  The la= nding gear structure absorbs much greater loads during ground operation in = the fore/aft direction.
I am glad the doors are work= ing well.  Awesome scenery in your video.

Chris,

your 2 piece carbon doors are working great. No flexing, no noise. After= loosing one original main door in-flight, I'm very happy with the new syst= em.
I also made a longer hinge on the inner doors. Since then I h= ad no more broken hinge. Also the inner door flutter after engine start is = minimized.

At what max. speeds can I safely extend= my gear? I actually use 120kts for gear down. When I arrive in our tight c= ircuit, my gears are good speed brake.
I think the front gear is = the weak point as it has to move into the airstream. The mains move sidewar= ds, so the air load is less harmful.

At what speed= s can I start to partly lower the flaps down to +5=C2=B0 or +10=C2=B0  = ;(below fuselage fairing). My flaps have a hinge on all the length and also= the 7bids glass
under the wing side of the hinge at all the leng= th. Max extension speed is 100kts.

Christian

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 point.  T= his door is the week link.  A handful have failed in flight and depart= ed the aircraft.  The outboard doors flex quite a bit under aerodynami= c loads.
On the other hand, I found the the outback = inner gear door can withstand the full 200 KTAS cruise speed - ev= en when detached from the actuator.  I had a rod end bearing fail back= at about 150 hours.  I was pleasantly=0A surprised to see the do= or remained on the aircraft.  -The rod end bearings have been rep= laced with stronger units made of a better alloy-
Ba= ck to door speeds.....
I am now flying with a three-= piece outback gear door set-up.  Like with the standard gear the = center door is attached to a new trailing link on the main gear. = These door effectively have no speed limit.  The only caution then be= comes the gusto with which the gear locks into place.  I have gon= e as high as 160 KIAS for extension speed. 
Th= e impetus for these doors was not to increase gear speeds, but to keep them=  from flexing open in flight and turning into air brakes.  <= /span>
