I got some time to think on it as well. I'm not saying this is a for sure plan, just an idea, things could change in time. Really appreciate the advice and do not hesitate to correct me at any time, I like it lol
Ft viggen group build!

Apple something brand cheap Walmart acrylic thinned with windex, applied with an airbrush is how I did that paint job.

My work bench at home is covered in seaduck and tailings from carving fb, and is a complete disaster. So is the floor. And I am sure I have tracked bits of fb all through the house as well!
I’ll have to give that a shot on my viggen!

I an absolute contrast to what you have goin on this is my work space as of right now. I think I need to get my mind off the planes as per say and de-clutter to free up some quality space. Maybe install some decent lighting over the work table too. There my day has a plan.

I like the twin EDF idea, and would be really interested in the thrust vectoring thing. Seems like something you would do for 3D capabilities
New work space. Feel like I can actually breath in here now. And see, set up some new lighting
Didn't take me to long and now I just want to build... to windy to fly even the Explorer. Maybe I'll mow the lawn instead lol
Looks great! I mean, Long grass helps cushion non-perfect landings (aka crashes) right?!

The space I fly in now is long grass and low shrubbery so I won't be writing off planes as easy anymore, and it's a 3 min drive from the house. Mind you there are trees around the perimeter that eat planes and they always look hungry. Tryin to sell the house as well so curb appeal is important they say
A mini quad motor like that might have enough power. One thing I do remember is trying a pusher setup with a blue wonder and it having barely enough power to sustain a controlled fall. To be fair, I was using a full powerpod instead of a firewall and I had to use a moderately heavy battery. However, try it with a 2205! I would love to see how it turns out.

I used the 2205 2300 with a 5x4.5 prop on 4s to power a northern pike. Had the perfect amount of thrust. And that was about 5 times heavier. So figure it should scream. Tho if the goal is 3d, lower kg and bigger prop would be better.
Your machine will probably cut all four in the time I hand cut one😂. I’m going to be doing the b and c packs like ft recommends, but it seems like that would work... I don’t do very much with the minis so I’m not sure what the abilities of those motors are.

I was thinking about doing something like this when i get around to starting mine. I think this would add a good bit of rigidity to the wing and help prevent delamination of the paper. Maybe even be able to flush mount the servos on the wing then.

I am a bit interested in having a hatch for the EDF unit but not sure how this was done or how effective it is? Any chance you can share more info on this?
Okay, what the 'H' why not.
It's not like I have nothing else to do right now.
@BATTLEAXE, are you in?

I so am in. Just gotta get the EDF and ESC to match.
Will this be your first EDF too?

Might it be ok if I ask you to print off some control horns for me, that is if your not busy

The hatch was first cut into on of my builds for another club member. He specified a 64mm build and after flying it he wanted to upgrade it to a 70mm EDF. He just cut a rectangular hole directly below where the EDF unit was fitted and started hacking at the internals. He initially glued the cut out piece back in but over time he replaced the "hatch" with a piece of ply which had a rectangular cut out in it in front of the EDF to allow more air in. He just holds the hatch in place with some reinforced packing tape!
At the moment I am building another Viggen for a different club member and he wants to have a slide in/out EDF pod to ease changes and the like. The only real issue in doing that is the access to the wiring and so I am slowly plodding through the build and his requirements! If I manage it I will post the method/pod.
One additional change was the use of a stiff plastic to make the thrust tube because the card was a little flexible and actually ballooned at full thrust causing a loss of thrust. The more rigid tube made a significant difference!
Have fun!

While I remember! The way they launch them here is to either do an underarm high alpha throw or to use and bungee launcher.
The hand launch has the bird almost stationary, (hanging in the air), and so far no real control issues but the bungee launches them as if they had rocket assist and as straight as an arrow!
Have fun!
