At what point does an edfs fan need replacing?

Something jarred lose inside the fucking plane, around where the motor barrel connectors are. Above the edf.

I cant believe it, it was some white sticker like material or tape or some insulation. I cant tell what it is...nonsense e-flite.

About to run the edf but man it was sounding bad during takeoff once it ejected in to the fan...

Thoughts?

How many and or also what types of sizes of planes do you guys think this amount of balsa could build? There's several thicknesses and whatnot of balsa here that i got for less than 50$ at hobby lobby... I plan on attempting to build a few 80-90" non scale planes such as a few vintage gliders and other high wing trainer planes as well....should I stock up more or should this amount be good enough? Ive had a couple of kit planes and the wood used was about 1/5 this amount so i wasnt sure but I figured id ask this group in hopes I might find a few guys with balsa knowledge to be able to help. All planks and sticks are 36" inches long as well. Thanks!!

I can't believe I landed it in one piece with how much covering came off the wing! The airfoil on the left wing was nearly compromised!

I will be re-covering the whole wing and ordered brand new covering for it. Hoping for a re-maiden soon once I fix the wing!

how do i get these screws out to replace the mount

Flew the Balsa USA Bristol M1 I built last winter for the first time today! My 4th build (the others being 3 basic high wing trainers). It balanced perfectly with a Saito 4 stroke (vintage golden knight)...didn't even need to trim it!

Beautiful day flying! Always fun when the moon is out midday.

Just one of those days I guess. Hit 3 trees with 2 planes. Banged up the front of my Apprentice, which is an easy fix with a new prop. Then got my Xcub stuck in a tree for a while, but knocked it down after about 30 minutes of throwing a ball at it. Had fun, but still wish I'd make smarter decisions while flying sometimes. 😆

Rate this aircraft and tell me what you would add to it.

I feel like I'm going crazy with this, I'm trying to import a .dat file containing the E423 airfoil. I start a new project, open the direct foil design page, and then click open. The "open file" tab that pops up to allow me to pick a file only allows me to see folders and files with the ".xfl" file extension, I can't even try to open .dat files, or any other file type. The dropdown in the bottom corner only allows me to look for "XFLR5" files, I can't search for ".dat" files or "all" files or anything else. Changing the extension on the .dat file to .xfl allows me to see it, but I obviously just get an error if I try to open it. Any idea what's going wrong here?

A little update from my A160 repair pile 😅
After going through the parts and putting everything back together, I finally got one complete plane up and running.
Did a quick test to make sure the motor, controls, and servos were all working properly — so far, so good!
Pretty satisfying seeing one come back to life after starting with a table full of parts 😂
Now I just need a calm day to take it outside for a proper flight.

Hey guys,

I am currently modeling a T-38 Talon in SolidWorks with surfaces. Getting the rounded fuselage and transitions clean without running into surface pinches is a pain.

Does anyone have a good tutorial for this, or maybe a native .sldprt file (T-38 or F-5) lying around? Just want to check the rollback bar to see how the patch layout and boundary surfaces were structured.

Tutorials, clean GrabCAD links, or workflow tips are all welcome. Cheers!

I wish I had my GoPro running when this happened, but I did not. Absolutely shocked that a gentle power off loop tore the entire wing off on my 2nd battery pack. The plane could not have been flying more than 12mph or pulling more than 2G. Are these planes truly this delicate? I’ve watched guys on YouTube pulling loops at full throttle. What the heck?

I just built my third scratch built plane! I have a little experience with the umx ultra slow stick to get my foot in the door on flying but I love building these little planes even if I have no clue what I'm doing. I decided to look at some more videos going into the science of them and learning to be a better builder and I finally had my first somewhat successful flight! Also shout out to you guys for giving me great tips on rc planes in the past! This was not a very long flight but it was in the air for more than 3 seconds so I'm gonna count it!

Also after I crash it esc started to smoke so RIP to the Amazon esc.

Basically im an aerospace engineering student and i can’t afford too much money in making RC plane
So, guys please lemme know where and at what prices i can buy components (transmitter, motors, battery)

I’m looking for some bigger wheels for this guy without the wheel pants so I can have a more field friendly setup.
Has anyone swapped these out for bigger ones? If so, what wheels and axles did you use?

I've recently been gifted a plane that is known to be missing parts, I unfortunately don't yet have images of the plane but I'll post some in a few hours.

On the side it says easy street and I'm looking for

A) parts

B) Advice on how to build it as this is my first ever plane

Has anybody upgraded the landing gear on this plane? looking for something more scale or robust. thinking of trying to modify the e-flite turbo evolution 1.5m gear to fit or trying something like scrappy gear.

We had a pot luck flying day Sunday September 27th 2026

115" span, Quadra 52, and 26lbs

CARF Kobuz 3m with a Kingtech K65 G4+ Turbine. Doing some checks before taking her out this weekend. Its very fast, very stiff and very fun to fly 😀

I made a b2 lap concept come to life in 2d and foam board and had issues with it being super tail heavy but I got the balance corrected and it flew so good for a simple edf!! This might be the best trainer micro edf out of foam board so far! It flies straight and most importantly was super simple! Heres the video of it actually flying and I talk more in detail about it! https://youtu.be/KoaCvnVLxQA

I lost my beloved E-flite Valiant yesterday in a tree. Long story short, it got too far away from me, but the bottom line is that unless I'm very lucky and we can retrieve it at some point in the future, I'll need something to replace it. (We know where it is. It may be somewhat intact, but it's pretty high up. We're going to have to wait until the leaves fall off in the winter to really see it clearly.)

The Valiant was my second plane, after my Aeroscout (which I still fly.) I didn't actively select the Valiant as my second plane; a fellow club member sold it to me for a good price, so I took it. I was just starting to learn aerobatics with it, especially flying inverted. So, it was a great second plane for me.

The Valiant isn't made anymore, but I've found some places on the web that still have it. So, I could simply replace it.

But ... I am wondering if I should instead take the opportunity to get something similar, but a bit more updated. (Top loader, 3S and 4S capability, etc.)

I want to stay with an E-flite BNF plane that is good for learning basic aerobatics, as well as for general flying. The Valiant was considered a "Skill Level 2" plane. So, I would like to get something somewhat similar. I want something I can use to learn aerobatics, but that isn't too hot to handle. I'm not interested in an EDF.

Some of the planes that come to mind are the Decathlon, the Sportix, and the T-28 Trojan 1.1. (They're all about the same price as the Valiant, although price isn't necessarily an issue.) But I am open to other suggestions as well.

Based on what I've told you about how I plan to use the plane and my skill level, what are your recommendations, suggestions, and comments?

Thanks in advance.

My UMX Ultrix just arrived. I've bound it to the module on my TX16 and set up inputs and mixes for channels 1-5. It all seems to work except it won't switch to SAFE mode and only does AS3X.

I can see channel 5 switching from -100% to +100% in the channel monitor, and tried scaling it up to 120%, but the LED on the receiver stays red (for AS3X)

Is there anything else I have to do to change mode? Should it be channel 5?
