The canards are not used to control the plane. They just serve as flaps, so I had had to put two functions into a space which was previously used for only one. There also some things missing on the model or things I am not satisfied with. The side air brakes on the fuselage, pitot tube on the vertical stabilizer and air intakes for cooling electronics are missing. The thrust reverser is upside down since there was no other way how to put it to the engine nozzle. This is it-3 months of my work (of course not every day and all the time). Hope you like it as I do. Video to come soon. THE GALLERY Edited June 16, 2011 by grohl Quote
Zerobricks Posted May 31, 2011 Posted May 31, 2011 Nice use of plates for surfaces in the back! Thats a lot of functions, you should make a vid! Quote
DLuders Posted May 31, 2011 Posted May 31, 2011 This is very nice! Do you have a picture of the Jaktviggen next to any of the other aircraft in the "Grohl Air Force" (F117 Nighthawk, F14 Tomcat, KA-50 Hokum, Mi24 Hind, Sea Harrier, & Su-47 Berkut), or are all those dismantled? Quote
JunkstyleGio Posted May 31, 2011 Posted May 31, 2011 Nice Job. I'm not a fan of any "machines of war" but you surely did an excellent job on this model.. Can't wait to see the video... Quote
trekman Posted May 31, 2011 Posted May 31, 2011 Well done. The jet has nice lines. Interesting use of pieces. I like the variety, including the older toggle joint, which appears to be the toothless version. Looking forward to the video. Quote
DLuders Posted May 31, 2011 Posted May 31, 2011 (edited) Grohl's model is very close to the real Short-Take Off and Landing (STOL) aircraft: Edited May 31, 2011 by DLuders Quote
dhc6twinotter Posted June 1, 2011 Posted June 1, 2011 Very nice! I love aircraft mocs! I'm looking forward to the video, and I'm especially interested in the RAT, reverse thrust, and elavons mechanisms. Nicely done! Quote
Tomik Posted June 2, 2011 Posted June 2, 2011 (edited) It is awesome model with as many functions as I've got lost in them. I'm looking forward to watching video to understand what it can do... Edited June 2, 2011 by Tomik Quote
grohl Posted June 2, 2011 Author Posted June 2, 2011 Nice use of plates for surfaces in the back! Thats a lot of functions, you should make a vid! Surprisingly, the Czech AFOLs think the opposite way. I would rather use the panels, but UNIMOG is still not available And the plates allowed me to put the numbers on the wings. I will make the video as soon as the sun makes its way through the clouds in Czech Republic. This is very nice! Do you have a picture of the Jaktviggen next to any of the other aircraft in the "Grohl Air Force" (F117 Nighthawk, F14 Tomcat, KA-50 Hokum, Mi24 Hind, Sea Harrier, & Su-47 Berkut), or are all those dismantled? David, unfortunately all of them "passed away" to help the others grow. But I can make a photo with the 1/72 scale Viggen plastic model or my new Manta police helicopter, which I am going to show you soon. Quote

Jurgen Krooshoop Posted June 16, 2011 Posted June 16, 2011 This is indeed a wonderfull creation Quote
JunkstyleGio Posted June 16, 2011 Posted June 16, 2011 Nice presentation! So much details, so much functions. (Again...) AWE-some! Quote
DLuders Posted June 16, 2011 Posted June 16, 2011 This has got to be the BEST Lego Technic fighter aircraft ever made! :thumbup: :thumbup: The shows everything very well, and is true to the .

Sokratesz Posted June 16, 2011 Posted June 16, 2011 Wow, that is gorgeous. How did you get all the grey technic platework though? Quote
Phantom59 Posted June 17, 2011 Posted June 17, 2011 Grohl's model is very close to the real Short-Take Off and Landing (STOL) aircraft: Great Vid I can not think of any other fighter aircraft in the last30 to 40 years that can do a turnaround like that Quote
grohl Posted June 18, 2011 Author Posted June 18, 2011 (edited) I am glad that you like the plane as much as I do. Here is one video with the grey version, unfortunately vithout the STOL maneuver. Wow, that is gorgeous. How did you get all the grey technic platework though? I own two 8052s and the rest is bought from Bricklink which was not cheap. I spent more than 80 bucks for the parts I needed to finish it. Edited June 18, 2011 by grohl Quote
Superkalle Posted June 19, 2011 Posted June 19, 2011 Grohl's model is very close to the real Short-Take Off and Landing (STOL) aircraft: A small anecdote. When I was in the Swedish Army, I remember one time we were supposed to do an exerscie in the middle of the forest, setting up defence perimieters around small stretch of straight road. I didn't understand why until I noticed the hidden airsupply trucks and mobile radars. It was then I understood the purpose of the STOL aircraft, to be able to use ordinary roads for take off and landing (when the normal airfields have been blown up by the enemy). This is also partly how the swedish airforce (at war) is setup and why Viggen (and it's successor Gripen) are STOL aircraft. Quote
Phantom59 Posted June 19, 2011 Posted June 19, 2011 Great Vid I can not think of any other fighter aircraft in the last30 to 40 years that can do a turnaround like that I should have said great model as well Quote
Nightshroud99 Posted June 19, 2011 Posted June 19, 2011 Just seeing this now Outstanding Job!!!!!!!! Quote
DLuders Posted October 29, 2011 Posted October 29, 2011 (edited) Using Grohl's 754 photo instructions of his SAAB JA-37 Viggen aircraft, I compiled a single, 25.4-MB PDF file that can be downloaded from MegaUpload SkyDrive here. The 754 photos are numbered, plus I added a cover sheet with Grohl's description from his Brickshelf gallery. Thanks, Grohl, for sharing the MANY photos! Edited February 8, 2012 by DLuders Quote
