I've been 3d printing for 5 years now and tried a lot of different brands of filaments and Colorfabb has always been my favorite! It's just very reliable and has the best feel and appearance. The white pla is my choice for lithographs.

I'd agree with this in a lot of RUclips channels. This video didn't seem too bad, however, I have the "voice" channel on my Polk sound bar turned up pretty high because I got sick of having the same issue on almost everything on youtube. Shockingly some stuff on other channels is STILL to loud, probably completely unwatchable for anyone without that feature!
I just watched the review of the Baby Blender from many years ago. They quipped "a flite test blimp would be cool" and I saw this and I thought: FINALLY! But no. They didn't build a "plane" with helium bags in it. Oh well. Some day. Maybe I'll have to do it myself.
Or you could design, test, change, test, redesign, test, amend, test, scrap, design v2, test, change... rince and repeat... yourself, and then fly what ever you come up with. The design is free. No one ever claimed that you would get a RTF setup left on your doorstep.

Try wearing latex gloves when flying in cold weather. They help to keep your hands/fingers warm and you can still feel the sticks and switches on the transmitter.
Printed, assembled and maidened the free version last week, with PLA fuselage and LW-PLA wings. Flies absolutely great. Slow and fast, little acro, no problem. Dropped an Arduino Nano and a few WS2812 LEDs into the wing. Looks great due to the opaqueness of the LW-PLA and the internal structures. Somewhat like a dragonfly wing.
Interesting idea: to demonstrate how easy and quick it is to get back in the air with one of these planes, intentionally auger in, which would start the clock, and then reprint out the parts needed and rebuild the plane. It could also be a test to compare regular PLA and LW PLA in terms of durability. Maybe do a test with PETG or TPU as well.
Can you guys make a video on 3d printing tips and techniques? This technology is finally becoming wide spread, and all we need for 3d printed planes in the hobby to be a success, is a thorough tutorial on the 3d printing process
LWPLA is amazing.. one thing to note about the pla version. On really cold days.. We needed to leave it in the sun to warm up so it wasnt too brittle. The plane flies amazing with lwpla
Started printing one the day the video was posted. Haven't been in the hobby for a very long time, you guy's have inspired me to get back in. One thing you didn't point out in the video was what motor/ battery you are using in this build...inquiring minds would like to know. Happy flying and keep doing what you do
Roughly how much in PLA/lightweight PLA does one of these cost? Say for instance it was crashed and the air-frame was destroyed but they electronics were fine how much would it cost to rebuild?
Thank You for providing the free files. I'm almost complete on printing everything in PLA + filament and the parts are beautiful using the provided gcodes. Thanks for making this possible. Keep these designs and videos coming.
@Ordo Militaris Radio TV I agree with you colleague. They began to make just entertaining content, while earlier there was educational content. Probably a crisis of the genre (
What I'd like to see personally would be flitetest models that have both foamboard and printable versions. Foamboard for those that don't have a printer, or want something that's cheaper to replace in a crash, and STLs for those that have the printer and/or want the extra performance. A video comparing them would be an interesting watch 3D Printers aren't as expensive as they used to be, by a long-shot. Even my $150 Tarantula could print one, and that's cheaper then a nice radio. They've fallen in love with 3D printed air-frames because they've got the same performance as commercial models while still costing way less.
@@DFX2KX I've already come to the conclusion that I don't want to make light planes. They do not have enough space in the fuselage, it is very inconvenient to place electronics. Still, the practical use, as opposed to a few minutes of flight for a RUclips video, is a different thing... A light aircraft is a problem in windy weather and a small battery capacity, hence either the inability to fly at all or a small flight time. Yes, you can come with a backpack of batteries, but not everyone is comfortable.
The axle roll rate was impressive I kept waiting for the lightweight pla plane to just disintegrate I was waiting for both of them to disintegrate really but I'm very impressed I think I'll be getting myself some light weight filmament to play with.
Thank you for the wording you used when mentioning the weight difference. It's not that one is necessarily better than the other, it's just different. Unless, of course, it's too heavy to obtain lift. LOL Another advantage I see to the 3D printing is you can print it in different colors and save time painting.
Cant wait to print this, haven’t printed a RC plane because all the free versions so far didn’t look promising enough until now with this video. Going to have to figure out what motor to run though
Because some people in the comments asked. Here are my personal experiences with this build. I am using a "Ender 3 v2" with simple black PLA (from Verbatim) (Ender 3 or 3 Pro should work quite similar). Still in construction, but looks promising. Created the gcode myself from the STL files with "Cura". Make sure to stick to the instruction page about the layer settings. My biggest problem was the bed adhesion. Fixed it by using a brim on some parts + blue tape. Estimated costs (related to Germany) ~ 220€ - Ender 3 v2 ~ 15€ - Filament (~600g) ~ 20€ - Small stuff (ruberbands, rods) ~ 200€ - Electronics (did not puchased the cheapest (stabilizer + telemetry included)) + remote control (already exists) - 2 weeks of printing (in spare time). - 2 months already of learning how to tweak 3D print settings (printed 3 parts twice because I was not satisfied with the result (most likely temerature, print speed and fan speed adjustments)). So it is definitely not the quickest and cheapest way to start into the hobby, but I had a lot of fun already with my 3D printer. And as long as the electronics do not brake, I can easily repair everything for almost no cost, just some time and effort.
It's not impossible because he didn't specify the amount of air it is lighter as. One cubic meter of air has a mass of 1kg so both those planes are indeed lighter than 1 cubic meter of air.
Checked out Edgewater park on the GPS. What is that crazy bright flare in the middle of the parking lot? I love that you can see the labels on the ends of the readi-runway
Do you ever connect the wings to the fuselage via a magnetic strip? See if there is a magnet strong enough to hold it together but then in an accident can pop off?
You could probably print the whole thing with one kg of pla (if you use MH build, you’re looking at about $20). It’d also most likely take a day to a few days to print (non continuous). Good luck!
I am putting one of these together right now. I am super excited to get back into the air with this model. It has been a loooooong time since I had a controller in my hands... wish me luck.
Just imagine a 3d printed DLG, that would be amazing! I know that composites are always the go-to material for F3K flying, but being able to 3d print out a wing, tail feathers, and a fuse would be a dream. Although there would be a lot of problems with torsional stiffness in the wing as well as having to probably lay some form of carbon spar and obviously a carbon boom, I think the price you pay to print off everything would be much cheaper than buying an outright new plane.
Hi I've never flown an rc plane but I do have quite a bit of experience with drone flying. I have a 3d printer and was wondering if this might be a good trainer plane
I really hope FT starts designing planes that combine foamboard and 3d-printing. Foam for wings and fuse sides. 3D-prints for cowling, cocpit etc. It's the perfect combination.
where can i buy the hardware required for this build. got the electronics but i dont have anny idea where to get the pushrods and screws plz help me out
Just asking but is there any difference between the motors used in rc cars and the ones that rc planes have. And would a 12 turn rc car motor be good enough for a plane?
Can you make a series where you show the engineering part of your vids? Like show for example what airfoils you use, why you choose them, how do you balance each plane etc.
Great Stuff, our family 11, 13, 15 Y/o have all built foam trainers and been inspired to scratch build foam board planes. We have also crashed plenty of them as well :). 3D printed a few, but they come apart like a wine glass on concrete in a hard crash. If I may suggest bringing the background music down a touch, it is a bit loud over the voices at the end of the videos. Some suggestions would some more common house hold items to use like 2-liter bottles, or even an empty soda can (perhaps as a motor mount?) A plane that collapses into its self, like a kid's expanding flashlight sword would be an awesome, and compact way to take a plane to a field.
I’m sure I could research this, but, just because this is an episode about 3D printed planes, what 3D printer does Flitetest recommend? Which one did y’all use to print these?
After printing the model in LW-PLA did you need to do any surface finishing? Also did y'all swap the wing between the 2 planes at all and did the flight profile change because of it?
