200% FT Viggen for Flite Fest East 2017

#1
Well I figured I would post a quick thread about the large EDF Viggen that I am madly working to have ready for FF East. I should have started sooner, but many things (new house) have slowed me down. That said I think I can have it at least ready to maiden in time for FF East. This will be our first time coming and we are really excited.

I will do a better update later and more info on this big jet. Pictures to come. XPS 128mm EDF system (6 or 12s to be determined).

Well alright, another Wisconsinite! Can't wait to see the giant viggen. Where about in Wisconsin are you? I'm in Fond du Lac.

Of course we will all be wanting to see you succeed in this. Looking forward to meeting you and seeing your plane.

Sponz: Guess I should update my location. Used to be in Iola over closer to Stevens point. I was in FDL often for work. Was awesome living there for Airventure! Now we are back near family in the Duluth/Superior area. Still WI though.

LitterBug: Finish it! It is a great flying plane. Probably my favorite FT design!

Jim: Thanks! Time crunch now, but I am determined!

Here is the wing and a couple other parts I have done.

I created a top skin for the wing to make it stronger. Designed in SolidWorks it works pretty well. I tried it out on my standard size viggen.

Very cool! Awesome job so far on the airframe. Are you planning on hand launch/belly land or gear? Would be really cool to try to do the thrust revereser like the real one at that size!

Just going to do hand launch and belly landing. I originally wanted to do retracts, but time won't allow this close to FF. If I have time, I'll do thrust vectoring, but I doubt I will get that done.

My 100% Viggen had thrust vector on Elevator. Made for fun flying. https://www.youtube.com/watch?v=yPyK_5KE5O8&t=1s

Wow! This is looking awesome!!

From my recent experiences with lack of airspeed on hand launches, I'd say we might want to help you get a bungee or high start at Flite Fest to make sure you get some speed and altitude right away. I'll be bringing my bungee launcher, and depending on how heavy this turns out we might be able to double (or triple) up the cord and give you a good boost.

Thanks guys... and thanks for the offer to help get it in the air. I am hoping that with a greater than 1 to 1 thrust to weight it will just fly straight up out of my hand. But if not the bungee sounds like a great idea. My all up weight goal is under 10lb. With a 15lb thrust EDF it should scream!!! and maybe just rip itself apart... Hehe... either way it will be fun! ;)
