Great detail of an impressive build process. Could easily be a series of short videos highlighting particular steps of the process. Amazing craftsmanship. Most great designs are interactions, rarely is the first interaction have many perfect design features. Any interaction is just an example of the current lessons applied in an ongoing learning process.
Excellent work and perfect documented! Thank you very much for sharing! To cut the laminated Fuse I have seen a bit expander inserted in the spindle. Can you give me a link where to buy it? For milling fuselage moulds the most bits are not long enough and I could not find a expander for 1/4" bits.
really nice build! thanks for sharing. for the milling process: did you go on an offset for the epoxy layer? you milled the mdf First. than you put epoxy and than you milled again. that offsets if needed would be interesting.
Very nice work you are performing, I have only one question, wat type of covering film are you using for finishing the model, many thanks to share, greetings from Remi, Belgium
Wow! That is the best CNC and construction technique I’ve seen. The cutter used on the molded fuselage and other surfaces is tiny. Hopefully you can work out the difficulties in performance with more analysis and time.
Awesome clean build 🔥. Could you share the foam core thickness you’re using? Also, I’m curious about how you align your model for control surface hinges and hatch cutting on the CNC. Your work is truly impressive, and I’d love to see more !.
Thanks! Normally I use 1,5mm Airex core, but this fuselage I used 2mm. Its super stiff, but heavy. I think 1,5mm is best choice for F3A. Moulds have aligment pin holes, by using those its very simple to align it. I have milled matching holes to cnc table. CNC have homing switches, so it can calibrate it self and always know where my molds/jigs are located
@@nulas87 I have one more question about the wing lay-up. Are you using any layer on top of the foam core for sandwiching, or are there just two layers?
Hi! Great job, very neat and meticulous! I have a few questions, please answer them. Why didn’t you paint the model in the mold? You could have gotten an excellent surface and color. I am sure that gliders are painted in the mold, maybe it's different for F3A. What did you coat the mold with after milling? First epoxy resin(?), and then something green, what is it? Thanks!
your work is breathtaking, its just amazing wow.. Well Done. i have a few questions if you dont mind me asking and it would help me a lot if you do, 1. after you CNC the part what was that thing you brushed on the surface ? 2. what was the Blue color that came out of nowhere on the surface hehe 3. and how was it sooooo smooth man how did it became so clean and nice, no matter what i do my molds never comes off as clean as yours
@@andreasluder8091 its pretty precise, enough for model building. I bought all electronics and linear rails and ball screws from Germany company Sorotec. They have some cnc kits available as well, it may be cheaper to buy kit with all aluminium profiles and plates, than buy all parts separetly and design and cut everything by your self. I wanted special size machine, so I decided to do it by my self.
I'm impressed by your skill on CNC jobs! Can you share more of the finishing technic? I saw you seem to apply some epoxy resin bebore finishing pass, isn't it? And is the last coat automotive paint, or tool gelcoat?
When starting the video, I noticed the wing placement seems to be too much forward... just wanted to know, it is designed to stall bottom wing first or is it the top wing?
IMHO - While this is a FANTASTIC build and KUDOs to the builder, fliers like myself who rather spend our time flying, an ARF and/or PNP F3A/Pattern plane will do. There are a few ARF F3A/Pattern planes out there and since there are a few distributors who are now selling PNP BALSA AEROBATIC planes, the few F3A/Pattern plane distributors MUST follow them and offer PNP BALSA F3A/Pattern planes to us fliers. The distributors who are selling the AEROBATIC PNP BALSA planes - which BTW you can do the F3A/Pattern maneuvers - sell out of these planes VERY FAST and are OUT OF STOCK most of the time until they get another shipment from China - that tells anyone how popular the PNP BALSA AEROBATIC planes are and those type of planes are creating an interest in the RC plane hobby just like the ARF did YEARS ago!!! - IMHO
How do you get the mdf not to warp when you apply what I assume is epoxy or polyester resin? I just cut a thin sheet and after I applied resin it cupped upwards quite badly. I was using 0.75” mdf and cutting maybe half of that at the wing root.
impressive and professional work.. can you tell me what program do you use to use the CNC on the 3D model? I only use it for 2D cutting work but I would like to learn to work on mold models like you.
I noticed your exceptional set of equipment and was amazed... you don't seem like a simple enthusiast... do you do it for work? Would you then do me the courtesy of passing me the link to purchase that beautiful used product to disguise the model? I use my cnc as a plotter.
Wau! Nuista työkaluista vois olla jo vähän kateellinen. Osaat myös selvästi käyttää niitä 😅 Upeeta jälkee kyllä. Huomaa että tuo on huolellisesti suunniteltu. Toivottavasti saat koneen lentämään pienillä viilauksilla. Jatko kiinnostais myös kunhan homma edistyy
Outstanding work, why don't you convert it into a 3D file so that it can be printed in 3D so you can get people to fly F3A those who can't afford the costs of an F3A, just a idea , best regards.
Well, if you screw up the aerodynamics and basic weight and balance, no amount of fancy equipment and software will save the day. This is proof of why one should always do a sloppy prototype before moving to production grade processes.
Yes, I always need to try if I screw up everything or is ir success, many times its hard to know in advance. This was quickly and cheaply made prototype not for production. Also wanted to try few new production methods
Aircraft builders like to over-embelish the manufacturing process. Model aircraft fly well without this sort of thing. Good engineering adds simplicity not vulgar adornment.
Yes. I do this kind of thing as my full time job, so its not only hobby. Most of my machines and workshop is own design and self made from cheap stuff you can find from internet.
Amazing to see the process you take to complete a competition model, it takes me longer to complete a BaJ model, thank you for sharing
A seminar for precision building and 5star craftmanship.Thank you for sharing!
I like your work very much and wish to talk to you and learn many things from you. Really your work is a true inspiration for aeromodellers.
Thank you so much👍🏻
Wow, great use of the cnc and tool paths, especially when machining all of your features in the fuselage using the mold as a fixture!
The CNC work is impressive but your CAD skills are far more impressive. Beautiful plane, thanks for sharing the process.
Your cad/cam and model building skills are very impressive. Sorry your efforts didn’t quite work out like you had hoped.

That's amazing ^^ I enjoyed it. I'm rooting for you to have a beautiful flight.
I love watching perfectionists.
A question for you if you wouldn't mind: Is this a hobby for you OR a full-time job?
Thanks! Its full time job

Superb, as it should be.Congrats

Thank you. Its all painted. No covering film
@@nulas87 Many thanks, very well done, super nice finish
On the tail just change the lay up or what did you do?
Excellent craftmanship!
Wow! That is the best CNC and construction technique I’ve seen. The cutter used on the molded fuselage and other surfaces is tiny. Hopefully you can work out the difficulties in performance with more analysis and time.
Very well done mate.... Can you please let me know what you used to cover the wood surface(the green layer)
Is that gel coat?
It is normal 2k acrylic paint

@@nulas87 I have one more question about the wing lay-up. Are you using any layer on top of the foam core for sandwiching, or are there just two layers?
There is 50g glassfibre on both side of the Airex core
@@nulas87 Thank you for the clarification and quick reply. By the initial look I thought it was only the foam.

Thanks. After first machining, I brushed epoxy on it. Then final machining.
After white primer there is 2k acrylic paint. Sanding make it smooth lol😃
Many Thanks for posting video
would it be possible to get in touch re you cnc's, I am looking to build another and have a few questions after seeing your's , they are very nice
Hello, very nice work. May I know which CNC machine is used? I am looking for a CNC for model making. I really like yours. Thanks for the information.
Thank you! My CNC machines are own construction, very simple 3 axis with stepper motors
@@nulas87 Thanks for the quick reply. Does the CNC work precisely? 1/100 or in the 1/10 range? You don't have a plan by any chance? 😜
@@andreasluder8091 its pretty precise, enough for model building. I bought all electronics and linear rails and ball screws from Germany company Sorotec.

Beautiful!!!! Thank you so much!!
beautiful work. id love to see more of it. did you design the cnc machine or is it off the shelf?
thanks!
Thanks! I have two cnc routers. Both are own design. Most of the parts I ordered from www.sorotec.de/shop/
Spindles and VFD are from China
How do you go from machined foam to glossy finish in the mold?
do you consider any offset when you cnc the mould for paint thikness?
In this case not really. Paint layer thickness is about 0,05mm
When starting the video, I noticed the wing placement seems to be too much forward... just wanted to know, it is designed to stall bottom wing first or is it the top wing?

How did you fasten the servi inside the wing?
which glue is in use.?
How do you get the mdf not to warp when you apply what I assume is epoxy or polyester resin? I just cut a thin sheet and after I applied resin it cupped upwards quite badly. I was using 0.75” mdf and cutting maybe half of that at the wing root.
You have to glue several mdf plates together, then its more stable
Fantasic work !
Very nice manufacture. Why a biplane though, isn't that both a worse performer and harder to make
impressive and professional work.. can you tell me what program do you use to use the CNC on the 3D model? I only use it for 2D cutting work but I would like to learn to work on mold models like you.
Thanks! I use Mastercam. I am sure there is many free or much cheaper options as well. Result is the same.
@@nulas87 I'll try to take a look. Really congratulations for your work and the great constructive cleanliness
