F-104 Starfighter WIP test flight with tip tanks.

- I tested the Starfighter with a 85% FSA EDF exhaust duct. The previous flights were done with a 100% FSA duct. FSA is the Fan Swept Area of the EDF and by reducing the diameter of the exhaust duct, the speed of the exiting air will increase giving the model a higher top speed. However the amount of thrust will decrease making launches and vertical maneauvers a challenge. It’s all about finding the sweet spot between thrust and exhaust airspeed.
The Starfighter performed very well and didn’t seem to lack thrust even though I flew it with the tip tanks mounted. The F-104 is VERY fast and covers a lot of distance in a very short amount of time. At that kind of speeds it is quite challeging to keep track of the small airframe and its orientation in the air. I guess it is all part of the fun. - Розваги
I’ll most likely do a slight enlargement though as it’s easy to do using Cura for a 70mm
Beautiful model!
As I mentioned in your other video, patiently waiting for the files to be offered for sale, the tip tanks certainly make the plane look right. 😋👍
I know that I’m testing your patience, but I hope the final result will be worth the wait. I’m doing my best but still have to balance hobby activities with work and family. But I will get there 🙂👍
Awesome!!!👌🏼😎
Thanks 🙂👍
Please offer 90mm size also. I would like to make one and power it with turbine 4.5kg thrust.... that would look and sound great
May happen sometime in the future. I have a Kingtech K45G4 and a set of Freewing F16/F-104 retracts so…😉
What is your opinion on a novice possibly flying this bird? Great design & build! Thanks!
Thanks 😊 The Starfighter flies much better than most would think. Very predictable and without any bad habits. However, it is an edf which flies fast and covers a lot of distance in very little time. On top of that, the slim fuselage and short wings can make it dificult to see at a distance. So I would not recommend it if you’re a novice pilot. But you could print one and hang it on the wall as a model that would motivate you to practice your flying. Then one day…
Hello Michael. I am learning F360 and have made a few model airplanes. What I have noticed is that once you get them completed, there isn't a lot of support to teach how to make the control surfaces or internal supports to make them function as a R/C . Could you point me in the right direction for some help. I purchased the Starfighter from 3dLabs to fly and try to reverse building it but I am hoping there might be a better instructional video. Thank you. John
Hi John
Designing RC model airplanes is quite a complex task, as you´ve already discovered. The main task can then be split up in three subtasks: Making the solid shape of the model including aerodynamic considerations, designing the inner structure to make it strong enough for flying and finally fitting all the systems for power and control. Some of the tasks may overlab and even work against each other. it´s all part of the fun of designing airplanes.
I don´t know any tutorials that show you all the tasks. It´s all about trial and error. Some of the solutions that I used on my first 3D printed models have been ditched in favor of other solution. And it it OK to get inspiration from different designers. So it´s a good idea to buy a few designs from different designers and learn how they approach the many issues related to airplane design.
My best advice to you would be to design as many models as you can but keep them simple at first. Start with a simple 2 channel glider with 1000mm wingspan. Learn from that and then optimize the design and add a bit more to the design like ailerons. Then optimize again and try to make the design lighter and test if it will survive test flying. This way you will get a good feeling of which solutions work well and which do not. And being a small glider you can print a new iteration in a couple of days.
Good luck with you designs

Yes as you have pointed out the true facts. Where did you get your experience? I have built Balsa models since I was 14 years old and now I'm 65 and still learning new things everyday. What fun . Fusion 360 has me hooked ! I am in awe of what you created. I look at your design and ponder. My next trial and build has been fun thanks to your efforts. Thank you.

@johnmainville6512 You were late to the party, John! I started building and flying models when I was 10 😜
There is no magic bullet regarding CAD. It all comes down to many, many hours of work and the urge to improve. I use Rhino 3D for my work and have at least 25 years of experience with it. But it is only 5 years ago that I shifted to surface modelling and that gave me the tools to model any airplane that I like in a very true to scale way.
Many people have asked me, what program I use, because they want to be able to create models like mine, but the truth is that it has very little to do with the programs. It’s all about putting in the hours of work and gaining experience.
I’m glad you’re having fun designing in Fusion 360 and learning new things. Keeps the brain fit.
And flying a 3D printed model that you designed yourself is immensely rewarding and excillerating.
My next goal is to print and build a big version of my Saab Draken powered by a 45N turbine. There’s always new things to try with this hobby 🙂
BTW. I’m 58 😉
And thank you for your kind words. Much appreciated. I’m very pleased that my work can inspire others.
Fantastic that you managed to get such iconic plane in the air and fly well... What design program do you use ?
Thank you 🙂 I’m a bit surprised myself that the model flies this well. No bad habits at all. But you have to keep an eye on the model all the time. It gets small very quickly.
I use Rhino 3D for modelling.
@@michaelghammer With the latest "spring" code from 3D Labprint, couldn't resist to buy your files. Well designed, love it. ( Also bought your J35 to support your work )
Thank you so much for supporting my work. I’m sure you will like both models. But I urge you to build a bungee launcher. Both planes flies very well, but the launch is challeging. Especially the F-104 should be bungee launched. But once you build it, I’m sure you’ll love it. Such a cool way to launch a model And very safe!!!
@@michaelghammer I will build a bungee launcher, so the focus can be just on the plane. Thnx again for your reply.
A very wise decision 🙂👍 Have fun with the printing and building. And good luck with the flying.
There are threads on both models on RC Groups if you want to share your experiences or have questions: www.rcgroups.com/3d-printed-planes-1006/
Are the stls. ready to be adquired.🤗?
Not yet, but things are progressing well. Files will be available from 3DLabPrint.com in the autumn.
@@michaelghammer ok . I will have my catapult ready by then
i can't wait when it goes online
@@michaelghammer If I look on the weather here in Germany, then you are late ;-)
Rain, cold, stormy - not bad for beginning of winter ....
I know and I’m sorry but I’m on vacation in Portugal so no time for CAD work. I will do my best to make the Starfighter worth the wait. And you will have all winter to print one Starfighter for flying and one for hanging in the Living room 😜
Den er alså flot. Glæder mig til at prøve at printe den når den kommer.
Mange tak, Jens Bo. Du skal nok blive glad for den. Den flyver rigtig godt.
