Perfect! I was hoping to find a guide for making a solid foam version of one of these with templates and sure enough! Been inspired by my 6 cell powered FT Superbee to make a 6 cell powered FT Mini Arrow, but the funny foamboard airfoil shape didn't seem right. Very helpful video and website. Cheers!
Went to hobby shop to buy 3mm carbon fiber tubing for the reinforcing part only to be talked into strips instead. just as well on seeing you said the same.....how did I miss that. sorry if I messed up your views, I personally have watched this over 30 times trying to follow what you're doing! haha. cheers, Daz
Andrew Newton Thank you Andrew :) That was very kind from Mario to offer me a chance to be featured between all these awesome RC allstars! Looking forward to your next videos :)
in my part of the world quite impossible to find these insulation foam as we are 365 days hot and sunny :), probably can substitute with foam from those ice container
It flies so well Andrew, do you think this is because of the motors position being nearer to the wings C of G..?.....Or am I imagining how well it flies...? A slightly larger version for FPV would be interesting with a miniature FC in it..
Andrew Newton I think its a combination of sweep angle and having the motor where it is...plus the sweep angle on the TE too...More mass nearer the C of G..?....It just works very well....I have seen many wings suffer from nodding and at their very worst tip stallers resulting in a death spiral..Where are the dimensions for the wing planform?....I found the section templates ok.
Andrew can I ask what CG reference point you are using on your Arrow ? The FT foam arrow says about 44mm in front of the motor wall. If that's the case my servo arms are at that point so I might suspend it with paper clips for a balance point. It's just a bit awkward using my fat fingers. 😕
Well I just found out that you should not use Diggers Fiber glass resin and Diggers Hardener on this foam as it melts the foam. I was adding some carbon fiber mate to the battery box. It is all set but very thin on the bottom. FYI
Andrew Curlin this looks like Clark Y. You can find online airfoil plotters - just choose the airfoil and the wing chord and it will create a ready to print paper template - just cut it afterwards from ply.
Andrew Newton hey there. Yeah I did, I saw you images, I was more referring to a plane with all the sales on one sheet like what FliteTest does. Thanks
Hi Andrew!!! First of all compliments for your channel!!! I always follow you because i'm a hot wire cutted planes lover too!!! I'd like to build a mini arrow too and i downloaded your templates but i'm not able to understood which airfoil you had used! It's written that it is a type of clark z but it seems to be quite different from that one: airfoiltools.com/airfoil/details?airfoil=clarkz-il I really hope you can help me!!!
Greetings and thanks for the compliments. You are right, it started as a Clark Z but I stretched it out and thickened the trailing edge to mimic the Flite Test build shape. The templates work very well, we have built 6 so far and they are proving to be fast fun and tough. Good luck and let me know how you go.
Thank you for your quick reply!!! I have another doubt (hoping to not annoying you): in your video about the cutting phases i cannot understand how you choose the right position of the templates on the foam panel! Normally i use to align the leading edge of my template with the foam edge and i suppose you use a similar reference too! Can i ask you what is it? Alternatively, can you say me the length of the root and tip chord? Thank you again for your help!!!
Root and tip chords are in the blog post linked in the description. I line the templates up with the front edge of the foam then move them back a few mm to allow for the cut.
Working on building your plane recently. Thank you very much Andrew
Good luck, happy flying

Thanks John. It's a great little wing design
Love your stuff, Andrew! Keep it up.
+Tim Williams Thanks Tim. Much appreciated.
+Andrew Newton :)
Really cool
+Nathan Knight Lotta fun

Strips or rod will work fine Daz. More views are good mate.
Looks like I'm going to be assembling a hot wire foam cutter :-)
+SomeGuyInSandy If you can find the foam then go for it.
I'm Planning on building one on friday with Albert Kim!
+7demo7 Oh yeah. Think about reinforcing the wing join / pod cutout. Everyone seems to be breaking it there.
You seem to be a pretty great builder :)
Very nice job and sweet explanations all along!
Thanks for sharing and have a great weekend
+ABMNS PRODUCTION Thanks Cédric, I saw your clip on RCShim and had to subscribe.
Andrew Newton Thank you Andrew :)

Good show man, keep it up
GREAT video!!! This is the reason for my Subscription!!
+Torch Fpv Good to hear it, are you going to build one?
I have built 4 FT arrows.. I did just make a hot wire, and this looks a lot more durable so yes I believe I will :-)
u are best!

+Nor Idzuwan Mohammad Yes that might work

+EnglishTurbines I does fly very well with minimal stall even during crazy manoeuvres. Why? sweep angle, taper, I dont really know, it just does.

+EnglishTurbines Initially I just used the Flite Test plans, but have my own outline template now, I'll upload that and let you know.
Andrew Newton Great, thanks, look forward to it....I have some Foam left I could make one of these from..

Hey Andrew .. love your work !!! - What size control horns are you using on the Mini Arrow and presuming they are glue ins ?
Home made ID card plastic horns and the hole is 20mm above the hinge. They pass through the elevons and glue to the bottom, very tough and secure.
Andrew can I ask what CG reference point you are using on your Arrow ? The FT foam arrow says about 44mm in front of the motor wall. If that's the case my servo arms are at that point so I might suspend it with paper clips for a balance point. It's just a bit awkward using my fat fingers. 😕
Should be the same, it's the same plan shape. I never actually measured mine, it just worked as is.
Well I just found out that you should not use Diggers Fiber glass resin and Diggers Hardener on this foam as it melts the foam. I was adding some carbon fiber mate to the battery box. It is all set but very thin on the bottom. FYI
Hi Andrew,
No washout for Mini Arrow...?
+SladkaPritomnost No washout and totally flat bottom, easy build
do you have the airfoil templates?
Yes
is there a link we can download them from?
Andrew Curlin this looks like Clark Y. You can find online airfoil plotters - just choose the airfoil and the wing chord and it will create a ready to print paper template - just cut it afterwards from ply.
I realize, I have made many Hotwire wings, I want the dimensions
sir, can i use 6045 propeller on my A2212/10t 1400kv brushless motor for a boxler wing
Yes it would be OK but a 7x4 would be more suitable
do you think i can build this with under 250g? with smaller lipo, smaller motor, no covering film?
what was the raw weight of just the wing halves? if its 150 or belowm, its fine. because all my equipment is rougly 92 g
Yes maybe but it would be fairly prone to damage, this foam is not like EPO
Can we use polyurethane foam for making these birds
Not familiar with polyurethane foam. But you can use poly styrene from packing boxes
what is the weight of the mini arrow wing
I'd have to read the description to recall it.
Which foam did you used
G'day Andrew. I absolutely must ask where you found that t-shirt! I grew up watching Red Dwarf and cracked up when I realised what your shirt said.
Hi Josh, it showed up on Facebook somewhere. I'll find a link
Here it is - store.ministryofbritishcomedy.com/collections/rdfans
Hi Andrew. I like your chanel is perfect , I not can download The template,I need The real link. Thank
I'll email you the folder of plans if you want
how to print the airfoil template...???
Google search for the airfoil. Print on paper, use the printer scaling to adjust to your size.
I've made this mini arrow plane and shown it on my channel, if anyone wants a look. Thanks for the inspiration Andrew.
Excellent, I have subbed
Do you have a PDF template for these?
Have you checked the video description?
Andrew Newton hey there. Yeah I did, I saw you images, I was more referring to a plane with all the sales on one sheet like what FliteTest does. Thanks
That's all I have, maybe download the Flite Test one
Can you share the file for the wing templates? Thanks ;)
+fpvZeroo Yes I will very soon.

Same as the FT Mini Arrow, look here - www.flitetest.com/articles/ft-mighty-mini-arrow-build
You can send the zipCo wing to me , wink wink, lolz
