A big thank you to Grifflyer for the design !!!
The decals and a few panel lines are complete and it is ready for the maiden flight. The marking are my loose interpretation of the real aircraft. The final weight came out to 357.0g (12.59oz) and the flying weight is 483.0g (17.04oz) with a 3S 1550mAh battery. The decal artwork was scavenged from the internet and edited in Inkscape. Not sure when the maiden will be as we are all in lock down here in Pennsylvania, USA. My local field is out in a rural area so we will see.

That really turned out beautifully just like all your projects! You really have a high level of perfection on your models - they look way better than mine ever do! Great job!

Do you still have the 70mm beta plans?

Thank you all for the comments and support during the build! Yesterday was the maiden flight and overall the launching and flight was excellent. It was a little breezy with a crosswind and the plane handled it well. The 3S 50mm EDF worked well and suits my small flying field. With the exception of launching, most of the flight was at 50% throttle so I am more than pleased with the performance. Flight time with a 3S 1300mAh 45C battery was approximately 4 1/2 minutes and 5 1/2 minutes with a 3S 1550mAh 45C battery leaving about 25% capacity. I will have a better idea on battery performance when I actually get to spend time flying.
Final weight - Empty Weight - 357.0g (12.59oz) no battery / Flying Weight 483.0g (17.04oz) w/ 3S 1550mAh
Here is the maiden flight video. As usual it is short, less than two minutes of just the important info and highlights to keep your attention.

I’m curious about 70mm plans. Could you send me a copy?

@Grifflyer really did a great job on the 50 and 70 mm versions. My 70mm flies great on 4S but my 6S version when it is done should HAUL. I did add a rudder to the 70mm and I was glad I did in 20 mph gusting winds. Can't say enough good about this design.

I am almost done with the build I am wondering if the plane can fly with evelon on wings. I am thinking not to use elevator

@dehager Incredible work, looks awesome!
I had finally some time to continue piecing mine together. Turns out that for me the canopy is really the most difficult part to get right. Even though it folds and forms nicely, making it fit is a real pain. I'm on my second canopy attempt now, and it still doesn't align seamlessly. Need to try something else. Otherwise I've really enjoyed putting this together.
I also installed a rudder, since it doesn't add much weight. Rudder will be fun especially on FPV. I have to next figure out how to make some control horns, can't really print anything since the libraries are all closed.
Hopefully I can do the final assembly later today or tomorrow, after which I can move on to electronics.

Congratulations on the successful maiden. It flies great and looks beautiful doing it. We don't see a lot of foam board airplanes crafted with such attention to detail.

No that won't work, the elevator only needs one servo.

I haven’t been able to get a good look at the 70mm plans yet. They seem to be raster, not vector so I couldn’t load them in Fusion 360 to take any measurements. Quick question, is the entire plane scaled up to accept the larger fan? Or are the changes only to squeeze the 70mm in without changing overall dimensions? Thanks,
Guy
