On most images I’ve seen online there seems to be a strake there. It appears to be A extrusion I assumed for the rudder cable or a structural add on to the tail perhaps. It’s easy to remove. And if you can find more pics of your plane I can create your paint scheme as well. Thank you for the cockpit image as well. Any others would be very helpful.

I'll search for better images the coming days. I can't find them were they should be. :?

In the mean time (Other B4's) :
airliners.net
Cockpit Dash

I see the special detail you made in some other B4's indeed. Never saw it before.

The glider I flew also had a small rod in the vertical stabilizer to be able to pull up the tail and place another wheel underneath the tail for ground traffic. Like this one : https://www.airliners.net/photo/Untitle ... Rj2379UjNa

And I think you already know there is more then one version...

permitted to fly a number of aerobatic manoeuvres, it was not permitted to do inverted loops or flick/snap/quick maneuvers. The B4-PC11 was available with either fixed or retractable landing gear.
B4-PC11A
developed to perform inverted loops and was also able to handle higher g-forces.
B4-PC11AF
released in 1975, with full aerobatic capabilities.

As far as I know, with many PC-11A versions the stringer was added from the outside to make it fully aerobatic capable. Like the PC-11AF version which already had the reinforcement inside the fuselage.

Looks great :!: :D I think the outer leading edge of the wing should be a bit more backwards and the wingtips should be narrower?
Well, it looks like in the future I will probably even be reminded of my employer in condor... :mrgreen:

For additional infos, i found the following on http://www.lvb-segelkunstflug.de/Pilatus_B4.html
and translated:

The B4-PC11AF is fully aerobatic capable. A B4-PC11A can be converted by:

riveting a reinforcing profile to the rear fuselage (from the outside)

Additions to the manual and modification of the type plate

Later serial numbers were already delivered ex works as B4-PC11AF. Instead of the outer reinforcing profile, an extended stringer inside the fuselage is used by the factory.

Great thanks for the help. This really will clean it up. Have a great Easter and I will send some updates later on.

So don't be confused by seeing the horizontal at the wrong position, it's because the images for all the 3-Views I've even found have the same problem with the top and front views in an isometric/parallel view with the fuse slightly rotated. In other words it appears to be too far back but is not.

Updated wing tips, canopy, and nose to the drawing you sent for more clean up.

Yeah, I've been working there in logistics for six years. I practically grew up with pilatus, because my father worked there for over 40 years.

The club at the airfield where I live nearby had a B4 with a very special finish. It was all in gold with blue/green „chameleon colour“ stripes that changed colour depending on the angle of view.

Unfortunately it was sold to france and crashed spectacularly during an aerobatic flight because one wing broke off :shock: :( . Luckily the pilot was able to jump off with the parachute.

Well we never use drawings from modellers because they are almost always wrong..

2P, Patrick, would you be able to get some accurate drawings from your company? ;)

I still haven't found the higher res versions of my earlier posted pictures of the B4-PC11 #208 from 1974 that I flew as PH-387 in the Netherlands. I found out it is now registered as N484B and is flying in the US... So it has some updates on the dash.

And I found the specific sounds the metal panels make when they are stressed and unstressed. (Plop, Ploink, Plof, Plomp, Plonk) :lol:

And the way it sounds when flying by... Like an airliner... :lol:

Yes,

The first time you fly it (and we started with winch by default so then when pulling stick to over 4G then you heard it even louder) it was a bit scary... But after a few starts you get used to it and I have never felt safer in any glider then in this armored jet-fighter. You had the feeling that you would survive any mid-air. It also had a static line chute in it...

It's really a special glider. One of a kind...

The only negative is that it didn't want to touch down. It kept on going in ground effect... It just loved flying I guess... :lol:

Ok, i understand, that makes sens. I didn‘t pay attetion where the picture came from. I just wanted to show, what should be corrected. I think this one looks really accurate anyway :wink: .
I try to ask at my company as soon as i‘m back at work, probably next week. Bloody corona virus :evil: had interrupted our logistic and we had to shut down a lot.
