Excellent idea on the clamps! Any chance of sharing your files, would love to try your idea, but I suck at modifying STL files.Hey all.
Seems like folks are posting builds here so here goes. I'm fairly new to the hobby and, like many others, I found it very annoying to have to adjust all the components to balance. I'm not sure I'll use the battery/motor combo shown, which would throw off the balance. Currently drastically under-powered. Also I'm kind of weird about making things permanent in my projects. My solution, which seems to work very well, was to modify the parts to add M3 screw clamps. This lets you move the parts around easily as needed, then clamp them down in place. I was surprised what light screw pressure was required to lock the parts in place. Just had to snug them down gently. No glue except on the foamy bits. The flex in the clamps also allow the parts to fit nicely onto arrow shafts of slightly different diameter. I'm printing SLA so mods like this might not work well in FDM. YMMV.

Wing back
- Lengthened and fattened the little rubberband grabbies. Also beveled the rear edges to not cut the rubber band.
- Down-facing M3 screw clamp
- Fillets! "You get a fillet! You get a fillet! Everybody gets FILLETS!!!!!" Sharp internal corners make stress cracks, which was a concern in SLA. Turned out not to be a problem but it's a little prettier.

Wing Front, the "star of the show"
- Beveled, bigger rubberband grabbies.
- M3 clamp offset to allow use of original landing gear holes.
- Fillets, fillets and more fillets

Tail wire:
View attachment 240434
- Thickened a bit to fit width of typical M3 screw head
- Clamp
4ch servo holder:
- Clamp on only one side. Might be good to add a little slit to the other loop to let it 'flex' around different shaft sizes.
- Fillets
- My 5g servos didn't fit so I had to use 3.7g. What's the deal with that?

Holder:
- Clamp
- Fillet
- Would also benefit from a flexure slit on the fixed side

Ailerons, naturally.

I'm like, 90% sure the little Blue Wonder isn't gonna' cut it. I didn't use the printed motor mount because:
1) I don't like how it looks
2) It's an arrow. Make it an arrowhead. So I turned that on the lathe. Particularly well suited for this 'hole'-mounted motor type. Blue Loctite.
- Printed wheels also visible. Haven't secured those yet.
- Gyro, because I'm a coward

I'm using 3/32 TIG wire for the gear. Not sure if that's going to cut it.
- 'Wing rear' and 'Tail Wire' parts, clamped in place.
MIG wire driving rudder/elevator. I think I'll probably replace that or put it inside a tube.
I can post the files they are in onshape so they are easy to edit.Excellent idea on the clamps! Any chance of sharing your files, would love to try your idea, but I suck at modifying STL files
We actually weighed it the other day it it came out to 16.5 pounds lolIs it S250 (sub 250g) LOL!![]()
yea I think it is about 7.4 (K) lol16.5 lbs? Doesn't that convert to something UNDER 250 (K) grams?
Ciao, è la prima volta che scrivo su questo post. Mi piace molto la modifica che hai fatto, saresti così gentile da darmi i tuoi file per la stampa 3D? Grazie!Ciao a tutti.
Sembra che la gente stia postando build qui, quindi ecco qua. Sono abbastanza nuovo all'hobby e, come molti altri, ho trovato molto fastidioso dover regolare tutti i componenti per bilanciarli. Non sono sicuro di usare la combinazione batteria/motore mostrata, che comprometterebbe l'equilibrio. Attualmente sono drasticamente sottodimensionato. Inoltre, sono un po' strano nel rendere le cose permanenti nei miei progetti. La mia soluzione, che sembra funzionare molto bene, è stata quella di modificare le parti per aggiungere morsetti a vite M3. Ciò consente di spostare facilmente le parti in base alle necessità, quindi di fissarle in posizione. Sono rimasto sorpreso dalla leggera pressione delle viti richiesta per bloccare le parti in posizione. Ho dovuto solo stringerle delicatamente. Niente colla tranne sulle parti in schiuma. La flessibilità nei morsetti consente inoltre alle parti di adattarsi perfettamente alle aste delle frecce di diametro leggermente diverso. Sto stampando SLA, quindi modifiche come questa potrebbero non funzionare bene in FDM. YMMV.

Terzino di ala
- Ho allungato e ingrassato i piccoli appigli elastici. Ho anche smussato i bordi posteriori per non tagliare l'elastico.
- Morsetto a vite M3 rivolto verso il basso
- Filetti! "Ottieni un filetto! Ottieni un filetto! Tutti ottengono FILETTI!!!!!" Gli angoli interni acuti creano crepe da stress, che erano un problema in SLA. Si è rivelato non essere un problema, ma è un po' più carino.

Wing Front, la "star dello spettacolo"
- Pinze elastiche smussate e più grandi.
- Morsetto M3 spostato per consentire l'utilizzo dei fori originali del carrello di atterraggio.
- Filetti, filetti e ancora filetti
View attachment 240433
Filo di coda:
View attachment 240434
- Un po' ispessito per adattarsi alla larghezza della tipica testa della vite M3
- MORSETTO
Supporto servo 4ch:
- Fissare solo su un lato. Potrebbe essere utile aggiungere una piccola fessura all'altro anello per farlo "flettere" attorno a diverse misure di albero.
- Filetti
- I miei servi da 5g non andavano bene, quindi ho dovuto usare quelli da 3,7g. Qual è il problema?

Titolare:
- MORSETTO
- Filetto
- Beneficerebbe anche di una fessura di flessione sul lato fisso

Sono tipo, sicuro al 90% che la piccola Blue Wonder non ce la farà. Non ho usato il supporto motore stampato perché:
1) Non mi piace come appare
2) È una freccia. Trasformala in una punta di freccia. Quindi l'ho girata sul tornio. Particolarmente adatta per questo tipo di motore montato su "foro". Loctite blu.
- Anche le ruote stampate sono visibili. Non le ho ancora fissate.
- Gyro, perché sono un codardo

Sto usando filo TIG 3/32 per l'ingranaggio. Non so se andrà bene.
- Parti dell'ala posteriore e del filo di coda, fissate in posizione.
Timone/elevatore di guida a filo MIG. Penso che probabilmente lo sostituirò o lo metterò dentro un tubo.
I just toured OnShape and can't find them. What is your username there? Or can you share the names?I can post the files they are in onshape so they are easy to edit.
My username is Jed and the files are not for the small one they are for the 11 foot one that we made. Just so you know if you want the small one then you can go to flite test community association and download it for free It is probably linked in this thread somewhere.I just toured OnShape and can't find them.

I have constructed the FT Slow Stick. I don't recall any instructions about where to mount everything on the arrow shaft. Can anyone point me to directions when stuff is mounted? I am all but done with this masterpiece but don't want to spend to much time positioning then testing then positionion, etc. Thanks
At the top of the page, just below the thread title, there is an Attachment browser for the thread. You can look through the images to get a good starting point for parts locations. I loosely installed the parts and then slid the wing forward/aft to adjust CG.I have constructed the FT Slow Stick. I don't recall any instructions about where to mount everything on the arrow shaft.
