FT Slow Stick S250

Was looking at the plans for the Slow Stick S250 as a possible school project, and couldn't find any info on the plans for the fuselage stick or assembly dimensions. Also there is a servo tray called 4 channel. I am assuming elevons with a rudder in the 4 channel setup? Thanks!

The holes for the shaft are 7 mm.
The 4 ch tray does add another servo mount. Looks like the wing could easily be modified for ailerons.

Can we get a hold of FT and see if they can add some details to the plans.... like shaft length, where to put the wing supports on the shaft, etc
I have arrow shafts, and some regular carbon shafts (with same dia.) that I ordered way back when.

Im doing the 3ch build as we speak

Edit: Also what dihedral? How to form wing under camber curve.... I know they are free plans but all they really gave ya was the basic wing and tail shapes and some STL files (that need modded as the rubber bands wont stay on the little nubs) 🤔🤦‍♂️🤷‍♂️

Since there is also a 3 channel servo print, the 4 channel servo print more likely is for throttle, an ailerons, elevator, and rudder. In the video they show a 3 channel.

Trying so hard not to build one......


I may have to see if we have any arrows at work. We don't usually carry them but will occasionally get some in on return. If we have some.... I am building! Will print enough parts for combat at the field.....

I've used carbon arrows from Walmart for a number of projects. They work great and the price was around $3 last time I picked one up.

Building one now and I too would like some more details on the build. I took up archery last year so I have some arrow shafts on hand. They're 8mm shafts, however, so I had to modify the parts with bigger holes.

I am guessing, based on crude measurements taken against the video, that the front wing brace is 100mm from the front of the arrow shaft. You can use the front brace to set dihedral. The servo mount goes between the wings (there are guide holes for the wires in the rear mount.

The 4 channel option has a third servo mounted on top. As this is under the wings, my assumption is that this server uses opposing arms to operate ailerons on the wings.

These servo mounts are sized for 5g Servos.
As for the arc of the airfoil? I'm going to guess that the center section (there are 5 sections to the wing), is 2 or 3 layers of foam above the build surface.

Also note that the front wing brace has holes at the bottom for 1.59mm wire to be used for landing gear.

FT is probably working on a build video for this, I would assume.

Can anybody here recommend a 3d printing service and can you guess approximately how much the parts for this would cost? Etsy?

Many public libraries provide 3d printing services for reasonable prices.

Good suggestion, but it looks like none of my local libraries do it. One of them apparently tried out several years ago but stopped. Probably difficult for them to keep it running.

I saw somebody post a link to the Ender 3 Pro on sale for $200. Is that a good printer for what we mostly do here?

Thank you Josh and team for releasing these plans, going to bust one out... Did anyone see the specs for printing the .STL files as far as layer height or infill? I normally print stuff like this at .02 and 20% infill since smaller parts. Just checking what everyone else is using? Regards, Bob

I have an Ender 3V2 and it's a great low priced printer. Bought it factory refurbed from Comgrow and have had zero problems. Not shilling for them but why pay retail? Currently $179 tax free and free shipping. The other option is ask someone here to print for you, probably less expensive than a printing service.

Pretty sure you meant .2, not .02. ;)
I printed mine at .2 with 15% infill, which really only affects the motor mount piece as all the other pieces are thin enough that they'll print solid anyway (well, it affects the 4 channel mount too). In my case I used some Polymaker "pre-foamed" LW-PLA (about 75% the weight of regular PLA) that I had laying around.

I'm planning on printing some simple hubs that will go in slices of swimming pool noodle to use as tires for the wheels.

The Ender 3 is a fine printer. The real specifications you need to look for is a printer with a 200x200x200 print volume as this is the most common print volume and most 3D printed plane parts are designed around this volume.

I have a question for you. Do you think the the original hole in your 3D printed parts were 6mm ? I see were you needed to drill your parts out to fit your 8mm shafts. I have done a search on line and there seems to be a lot of 6mm arrow shafts out there.

Thank you for any help,

The hole is 7 mm. Measured in Sketchup.

I didn't drill them. I loaded the parts into Tinkercad and made the hole 8.3mm in diameter (giving me a little wiggle room). Then I printed my modified parts.

This was only because I save arrow shafts from my archery hobby (I'm a novice, don't ask me any archery related questions other than "How can I get into it cheap!") to use as wing spars or whatever else may be useful. I had three such arrow shafts stripped of points, nocks and fletching just laying around and this plane is a quick easy project. The arrows I use are 8mm. They're cheap carbon fiber shafted arrows I buy on Amazon.

I am printing the parts now. Has anyone found info on the placement of the wing on the shaft?

Microcenter has the Ender 3 Pro for $199 with a $100 off coupon if they do not have your phone number in their system.
