Cool! (I will Beta build that!..If you want..) Man! I didn't know you could just build it as solid and add the infill in the slicer! 😆

The F-16?

Sounds like a cool plane, we definitely need more people out here 3D printing and coming out with cool designs

It's a bit heavier but gets you a better surface finish that way. I think most of the models out there are vase mode or fully modeled since weight is the major downside of 3D printing

Not yet..I figured I should probably do a couple pre made ones since I am dead new to this! So I am doing this one: https://www.thingiverse.com/thing:6378131

I got the Creality K1 SE on sale for $250 and it seems to be a VERY capable printer! (And FAST! 😂 😂 )

Does it look like a good model?

Looks like a good one to start with. I got into 3D printing planes the same way - downloading a couple of designs and seeing how they go together. It seems to fly well in the videos

Cool, thanks! I would LOVE to do the Elipson Vortex...But that's not free...We gotta have more 3D printed plane designs!

Not sure I've seen that design, but eclipson definitely has some good stuff. Definitely need more people designing and publishing their designs

The plane now has wings
I'll probably finish it up this weekend

MiG 15 is pretty much a placeholder for swept wing fighter at this point, whether that's an F-86, MiG 15, F-84, etc. I'm probably going to stay away from a MiG 17 since it has more wing sweep than some of those other designs and in something I plan to donate to someone else, I don't want to add the possible bad characteristics from greater wing sweep. In real life, the MiG 17 was definitely the better plane, and I think it's the better looking one too, but in an RC format, the less swept wings will fly better.

Finished up building the sport jet yesterday and took it out for its maiden flights after work today. It's easily the best flying jet I've ever built and, without landing gear, possibly the best flying EDF I've ever flown. And it's fast - top speed was 104 mph which was towards the upper end of my predicted range and which makes it the fastest 4s 64mm EDF I've ever flow by a good 14 mph though there are definitely faster 64mm planes out there. I'll try to get video soon.
It's quite heavy, at around 1350g with the gear and about 100g lighter without, so I was worried about hand launching, but it was quite easy. The caveat is there was a bit of a headwind, so I need to try launching on a calm day too. It will try to tip stall if you pull back on the elevator hard enough, but that's about its only bad tendency and you can fly it through the tip stall since the ailerons remain effective. Power is excellent. The static thrust to weight ratio is only about 0.9, but due to its speed and low drag it can go vertical longer than I can keep track of it. You can cruise about 1/3 throttle or a bit lower which feels weird in a jet and it holds on to a decent bit of speed even at that throttle setting. There is essentially no coupling between the rudder and roll and the rudder is large and deflects a lot which makes knife edge flying extremely easy. And it lands well - you can hold about a 5-10-degree angle of attack and glide it in.
With gear on, it's still pretty fast and flies well. I didn't get a gps reading, but top speed is almost certainly lower. The suspension is maybe a bit soft but it's very effective. I'm not sure how urgently I want to fix that since hand launching is definitely the way to go.

Cool!..Now that I have a printer I can start building these!

You never realize how much you needed a 3D printer till you get one

Now that the sport jet is done, it's immediately on to the boundary layer ingesting flying wing which I originally planned to build first. The left wing is already printed
This design will also be LW-PLA but with much lighter construction than the sport jet since it's got a similar wingspan but will only be powered by a 3s 50mm EDF
