Sipkill FPV 1m Wing Build

[@andrewnielsen3178]

A minor point Andrew: when cutting wings it is best to start at the leading edge to minimise wire lag in the more curved area of the wing. As the cut progresses wire lag becomes more pronounced and this can have a worse effect at the more curved part of the wing ie the leading edge.

[@javieruriel]

I am really impress how nice and smooth you cut that foam, nice work.

[@AndrewNewton]

Thanks Frank, it takes a bit of practice and a few ruined wings.

[@ashleycollard8968]

hi andrew i love that you have your technique down to such a fine production line for such a variety of aircraft; yet another great video ! my only hint is using a small phillips head screwdriver dragged at an angle to encourage servo wires and the like into the slots you made for them - automagically centres them and keeps them from twisting hope that's useful - a minor repayment for all the "borrowing" of your ideas i will do once i get into foam cutting :)

[@AndrewNewton]

+ashley collard Thanks Ashley. Good tip, I'll use that.

[@arfintr1522]

Thankyou soooo much for providing where you source your foam!! I have had sooo many troubles in my 2 years of RC trying to reliably source materials for various projects.. Aussie woes -_-. I can't wait to make my own!

[@AndrewNewton]

+Arfin Tr Finding the right foam is a problem, good luck with your quest.

[@rossfraser7304]

Love your videos man ,great to see a fellow Aussie showing the yanks a thing or two !

[@AndrewNewton]

Punching above our weight mate

[@Bulgie]

This foam looks similar to foam we have here in the states, known as pink insulation foam, or pink panther foam. Extremely messy to work with. I like your build. Good to know I am not the only one unable to recover from an occasional stall with a wing. They are just so COG picky. Thanks for the video again.

[@AndrewNewton]

+Christian Prodanov Yes it would be the same foam. Works out to be the cheapest and best build material for me.

[@LaLaObeRoT]

Very, very nice. Thank you. I really enjoy your build videos, they gave me plenty of inspiration already.

[@Planty3125]

Andrew Happy new year happy to contribute as you share your tips and tecniques and get huges interest in the hobby. Keep up the good work and happy new year regards Leigh

[@AndrewNewton]

+Planty3125 Thanks Leigh. I'll start on a new build video today. Happy New Year, go build something.

[@turdferguson1756]

Cool build, and another enjoyable video!

Hello, how is it proper to take off with the wind or through the wind with a flying wing? Thank you, Goran

[@SladkaPritomnost]

love you channel, and metric system :)

[@AndrewNewton]

+SladkaPritomnost Yay for the metric system, and driving on the left

[@philippevasseur5306]

Thank you Good night

[@EnglishTurbines]

Nice one Andrew....pleased to see you having some FPV fun again...Concerned and surprised by the ease it stalled and then entered a vicious unrecoverable spin though, a shame....I have a Skywalker x6 to build now, and I have seen more than one of them crash and burn in the same manner...:(

[@AndrewNewton]

+EnglishTurbines It's interesting, I have not stalled like that since. Must have been the windy day and me not flying it smoothly. This close in, shooting gaps style FPV is more fun.

[@EnglishTurbines]

+Andrew Newton I just watched it again, it's a bit strange, a pretty high speed stall wasn't it?...Keep posting for us, its still blowing a Gale here...non stop wind and rain...:(

[@AndrewNewton]

+EnglishTurbines Just had a closer look myself. Inverted, going downwind (wind was about 15kn at the time) pulling hard up elevator. The stall is not really unexpected but the lack of recovery is not something I have experienced before.

[@racoiaws2010]

Mr. Newton if you have the time can you please do a video on flying wing CG, and elevons throw? that would help me a lot on my projects

[@AndrewNewton]

I'll add it to the list Max

[@racoiaws2010]

Thank you sir :)

[@mithun1st]

Your have nice management system

[@LemberTheMember]

Looks like a realy nice build i also build a 1m Wing some Weeks ago for FPV my Wing is a KFM 2 airfoil wing disigned by me and the Wing Fly perfect after some modifications like a flat nose with some weight in it sry for my Bad english i'm from Germany :)

[@AndrewNewton]

+leo ulreich Thanks Leo, good to hear from you

[@LemberTheMember]

+Andrew Newton hope that the Fpv gear arrive soon :)

[@DutchRC]

It allmost looked like a wood-grain after the hot-wire job :) Cool build video sir! Any idea what the after-loop stall is about / how to solve that? I have not encountered that with my wings (yet :P) Cheers & have a good weekend!

[@AndrewNewton]

+DutchRC Adventures I have not encountered such a radical tip stall spiral before. Possibly needs a thicker airfoil to carry the weight. I tried rounding off the leading edge a bit more and that helped but didn't eliminate the issue. I'll keep investigating.

[@DutchRC]

Do you allso have this stall problem in hard turns??

[@AndrewNewton]

+DutchRC Adventures Dont think so but have only tested in strong winds so far.

[@zenzaleni]

another beauty...cheers for this

[@danilovertuan]

all videos are awesome! congratulations! good job!

[@AndrewNewton]

+Danilo Vertuan Thanks, glad you like them

[@ficho1234]

Built "ZAGI" type wing once with sipkill profile, good only for speed, stalls quick and without any notice..

[@AndrewNewton]

Interesting, this did have a wicked stall tendency

[@MaddogTyler]

Great video, I notice that you seem to like hot wire cutting wings, I live in Canada and have access to foam board what is easier to do, and more durable for a newbie. Also is the Flysky FS-i6 still a good choice or would you go for FS-i6x. I might try your trainer design. What I like about your video's is you talk about the pro's and cons of the plane/equipment and you seem to give a good account of the equipment and what its limitations are. Things you can get from the box. Even if I never get flying have enjoyed watching. Cheers

[@AndrewNewton]

Thanks. Foamboard is easier to build with for a beginner but hot wire cut it much more durable. The FS-i6 is the best choice, more adaptable than the i6X

[@MaddogTyler]

Thank you for the response. Your hot wire rig is a nice straight forward design. Keep flying and thanks for sharing your thoughts and adventures.

[@elliptic_echo6885]

My wing has stall problems as well i think it could be just the design of a wing in general?

[@AndrewNewton]

I thought more sweep could have helped.

[@usarmyfl1]

That is very nice!

[@alfinidn810]

Iam searching for sipkill plans!!!! Do you have digitalized??? The sipkill plans

[@AndrewNewton]

No I just found an image and printed it to the size I needed.

[@philippevasseur5306]

Hello, how do I find the plan for this flying wing and the profile of the wing? Thank you Good work

[@AndrewNewton]

Search for Sipkill airfoil. I would recommend more sweep angle than my design, no plans sorry

[@philippevasseur5306]

@@AndrewNewton Thank you Good night

[@karankumarrao3459]

you are a perfectionist

[@AndrewNewton]

I wish I was

[@chrispychickin]

the spiral instability that it exhibited after dropping a tip in the loop looks to me like it has something to do with the pod (and thus the thrust line/vertical CG) hanging so low. Some sort of pendulum effect gaining momentum as it oscillates? Maybe i'm totlaly off the mark though haha. What's the wing loading? Also, I can't tell if you're aussie or nz, but do you know anywhere to get good EPS foam in nz? bunnings don't seem to sell the orange stuff anymore, at least where i live :(

[@chrispychickin]

Also, before you abandon the specific foil, maybe try adding some little electrical tape strip turbulators at the LE between 15-25% or so for the outer ~60-80mm. I use 3mm x 80mm double stacked tape, and do 2-4 of them per tip (spaced 3-4mm apart) depending on how the airfoil responds to it. Too far forward = extra drag, too far back and the turbulator isn't dealing with attached flow, and does sweet F-A I love your tidy building technique btw. I've had heaps of fails with hot wiring, but I'm keen to try and emulate this method closely in future. Thanks for the great vid!

[@AndrewNewton]

Aussie. Thanks for your thoughts on the wing. The XPS comes and goes from Bunnings, we still have it here.

[@factdesignbr]

so cool. love from brazil

[@AndrewNewton]

+Fel Ta Haha, love from Australia

[@factdesignbr]

+Andrew Newton lived in nz for quite some time... miss it heaps. God bless ya man!

[@SladkaPritomnost]

Andrew what sand paper do you use? I made some hot wire cuts but I couldn't manage packing tape to stick to the cut (dust and small imperfections are just not sooth enough).

[@AndrewNewton]

+SladkaPritomnost My sandpaper is Norton brand 120 grit. It is white to start off then wears down to dark grey after use as the anti clogging filler is worn off. I do make sure to brush and wipe off dust as much as possible.

[@flyextreme813]

Haha the ruler at 1:04 but very nice video and plane Andrew👍👌

Do you sale this kind of homemade products?

[@AndrewNewton]

No sorry

[@rexcotys7060]

COOL AND VERY INSTRUCTIVE! BUT, ANREW, BECAUSE I HAVE NOT EXPERIENCE, I HAVE ONE QUESTION: IT IS PSSIBLE TO MADE THE MODEL REDUCED PROPORTIONAL, WITH A RUBBER BAND MOTOR FOR CHILDREN???... BECAUSE I SEARCED, BUT I HAVE NOT YET, ONE! THANKS!

[@AndrewNewton]

Thanks Rex. I dont think this wing would be good for rubber band power. Better to have a long bodied conventional plane to allow for a long rubber band. I have not made one but there must be instructions out there somewhere. Keep searching and good luck.

[@rexcotys7060]

THANK YOU VERY MUCH, GOOD LUCK AND GOOD WIND FOR YOUR WINGS!

[@antoniomaureira6543]

Hi, do you have the plans??

[@AndrewNewton]

No sorry.

[@strictly4passion]

how does the landing not break the props?

[@AndrewNewton]

Setting the ESC braking helps, so the prop is not spinning when you land

[@strictly4passion]

thanks for the response.. but even the props arent moving anymore. wont it come in contact with the ground on landing?

[@gregorcekon5779]

Hey Andrew. How did you make the body of the plane here and in youts Synapse proximity Thanks

[@RCShufty]

Can I put my order in for one? :P

[@goldenval]

Nice design

[@AndrewNewton]

+VAL0PRODUCTION Thanks but it can be improved I think. Will try more washout, thicker airfoil, more sweep maybe.

[@yellowbusguy]

I built a Flite Test Versa Wing and it would snap when I'd try to loop it. That particular wing was not fun to fly.

[@AndrewNewton]

+yellowbusguy Interesting. This one is actually a blast to fly, just have to make the loops big fast and smooth.

[@SladkaPritomnost]

+Andrew Newton ...maybe installing vortex generators on the outboard 1/3rd of the wing might prevent this crazy stall characteristics..., it should be easy fix too... www.rcgroups.com/forums/showthread.php?t=2252309 Some builders make tip chords thicker to improve stall and control characteristics.

[@guardjets8815]

What type of foam is that sir ???please tell...

[@AndrewNewton]

XPS insulation foam, also can be blue or pink in some countries

[@Apple1grApe2]

what kind of packing tape do you use?

[@AndrewNewton]

I was using PPS from OfficeWorks but that vanished. Now I use Kmart coloured tape (about 45 micron) or I found some thicker unlabelled tape on Ebay. All my materials here - newtonairlines.blogspot.com.au/2015/03/materials-and-links.html

[@Theone28966]
