Looks like another great plane, after watching your past plane reviews all my questions were answered. Great resource for a lot of questions. You seemed a little tired by episode 9, don't burn yourself out. I too have watched your diving videos, liked the cuddle fish wanting your dive computer, they seem very curious/hungry not sure what his thoughts were. The other amazing thing is how vibrant the creatures are and how unafraid they seemed of your presence. Keep flying/diving and enjoy yourself, if this becomes a job you will lose you love for it.

[@AndrewNewton]

Thanks for the wise advice Maddog. Cuttles are wonderful creatures and seem so intelligent for their short 1 or 2 year lifespan. Winter breeding season is when the males are out seeking a mate and will investigate any shiny object.

[@badamson10]

That looks easy enough to try myself! You provide great information. Between you, experimental airlines, and flite test, I'm ready to give it a go!

[@AndrewNewton]

Excellent, go for it and good luck

[@carlossanchez5600]

I guess I am very close to completion at this moment. Thanks much for your help.

[@SmokeFlame1]

That's a very nice flying model. Nice for a beginner. I haven't flown RC for 40 years. I'll have to give this a try. Thanks.

[@AndrewNewton]

+SmokeFlame1 Thanks. Keep it light and it will fly slow and easy. Good luck.

Love the slope maiden video of this Newton Airlines 3 channel polyhedral.

[@AndrewNewton]

Me too!

[@d.jensen5153]

Greatly appreciate the detail you've provided here. You've baked in lots of ingenuity and lots of convenience. Most construction issues I can handle, but I'm always intimidated by wings. I may build the polyhedral FT Explorer student wing to put on my own instantiation of the Newton RET Pusher, just because I think I can muddle through Josh's well-documented wing build procedure. I seem to remember you mentioned once where you got your abundant supply of ID card material, but I can't remember the details. My very limited supply of old credit cards isn't going to get me very far.

[@AndrewNewton]

Thanks, yes the FT wings would work perfectly well. I searched on eBay for CR80 Blank ID cards newtonairlines.blogspot.com/2015/03/materials-and-links.html

[@d.jensen5153]

Thanks! A lifetime supply is on its way. Seems like a great material for strengthening foam at high load points. Wood is brittle. The moment it cracks, all strength is gone. You didn't mention the cradle that your wing sits in but it looks like either contoured ID cards or contoured icy pole sticks. Can't tell.

[@AndrewNewton]

Those are just strips of foam (adhesive draft proofing tape), could use anything to build up ridges to stop the wing from rocking side to side.

[@andyshort3300]

Hi Andrew, I was making Balsa wood models 50+ years ago with my wonderful Dad, You scratch built Pusher has Inspired me to try to make something like you have from Balsa wood,

[@AndrewNewton]

[@andyshort3300]

+Andrew Newton As for me making a Balsa wing Do you know any website, I can download a slow flying Glider wing Rib template? As I would like to mount a Gopro in the Nose.

[@AndrewNewton]

[@Pilesofplenty]

Thanks for the inspiration! Im going to turn my Hobbyking Slow Stick into something like this. I dont have a landing strip and Im quite over rebuilding the gear, motor mount, etc . It has a nice big wing, would be great for a biplane but it looks like it has been discontinued so parts are almost gone. I Should upload a video of its current state before I do, I turned it into bush plane :)

+peter verrone Thanks Peter. The latest version (3ch Trainer) is even better, lighter and cheaper to build.

[@jimpollard7440]

Hi Andrew, thanks for all your advice on the pusher plane. I did not use your exact materials and my plane is heavier than yours and measures about 900g without the battery. will this be too heavy to fly?

[@AndrewNewton]

Depends on the wing area. It won't fly slowly

[@jimpollard7440]

Thanks for that. bigger wings mean more lift and weight and faster speed means better lift but less control! I will reconfigure to match your weight. as a beginner I need slow speed to I can learn how to control.

[@pierretruchon4353]

look fun plane to fly, I will like to build one, my question is : where is the C.G. thank you for your answer.

[@AndrewNewton]

Hi Pierre. CG was about 400mm from the nose or 65mm from the leading edge. More information here newtonairlines.blogspot.com.au/search/label/-%203ch%20trainer

Sir, plz tell me the measurements details of fuselage (spequally below the wings)

[@AndrewNewton]

Link in the description

[@NotRelevant1]

I’m currently building my first rc plane and it’s turning out to be almost the exact same. The main difference being my fuselage is shorter and I’m actually having some issues because of that, so it may end up being even close to this when I’m done.

[@AndrewNewton]

Good luck, it's a forgiving design.

[@ramonmejias2178]

Hi Andrew I was wondering what's the name of the plane that you have that looks like the aeroscout but much bigger can you please let me know thank you

[@AndrewNewton]

Skywalker 1830?

[@carlossanchez5600]

Andrew, I am constructing one airplane very much like yours, only difference is height of the fuselage all other specs are the same, all is built I am just waiting for UPS on the aluminum rod for center dihedral, I'll post some pics when finished. Also would like your advise on 60% reduced same plane as a park flier for my grandson. Can I reduce all aspects to 60%, allowing of course, room for battery and electronics? I will take care later of motor depending on weight and thrust. Thanks, Carlos, Miami.

[@AndrewNewton]

Carlos Sanchez Good to hear Carlos. I think this would scale down well as long as you keep it light. It's a very forgiving design.

[@NOXFPV]

Great video.

[@Fukaka2343]

Hi i am using Depron Board to make the wings a KFm2 based version for the pushers, unfortunately making a polyhedral is a bit tricky, i have tried to cut the wing at the tip slightly, bend and then hot glue the seams but sometimes its either un-even on or the glue is too hot and burns through the foam. Can you please give some tips or maybe a video on how to to avoid disaster lol. thanks!

[@AndrewNewton]

+Abid Khan Abid, I think the thin cross section of the KFm2 would make it difficult using just glue to hold the tip angles. Maybe try simple dihedral with a bent aluminium tube holding the dihedral angle at the root. Like this kzbin.info/www/bejne/l5Kwl5x5fpaNZrM

[@Fukaka2343]

+Andrew Newton Many Thanks!

[@MartialArtLife]

I used normal 8045 prop in pusher model but i did not get the required thrust...Why? Please make a video about it✈

[@AndrewNewton]

Mounted facing the wrong way, or need a more powerful motor

[@MartialArtLife]

@@AndrewNewtonNo motor 1400kv but in puller plane i got lot of power

[@MartialArtLife]

@@AndrewNewton I will try again...

[@theoztreecrasher2647]

@@MartialArtLife The same prop/motor/battery combo will always produce more forwards thrust in tractor mode than pusher mod. The pusher pylon mount blocks off part of the driven air disc plus the air is vectored off at an angle. Like having the wind behind you versus off to one side when sailing a boat.

[@msalikansari1417]

Its a puchers Ariplane so can you please tell me the angle of attack of this plane. Also I wants to ask how much you tilt the motor about thrust line? Plz tell me!

[@AndrewNewton]

I havent measured them but AoA would be 3 to 5º and motor thrust angle about 10º

[@msalikansari1417]

@@AndrewNewton thanks for your help. I am building a pusher glider with angle of attack 3° and thrust angle is 4-5°.

[@abruptlyblunt]

arrow shafts don't weigh that much, why could you run a pair of them back to stiffen up the tail a little, 2 of them tethered together by a couple spot of epoxy so they can't twist would be quite stiff?

[@AndrewNewton]

I have done that for a speedy sloper and it works well

[@SubrataDas-nb6fl]

Sir plz tell me where is the cg point of this RC glider Plane ? plz reply me

[@AndrewNewton]

Can't recall, but it would have been about 55mm

[@kidszone6669]

So nice

[@rva1945]

Hi, nice model. I modified my Ftr Explorer with a carbon boom. Which is the weight?

[@AndrewNewton]

Thanks, weight is in the description

[@sainirchobby]

Which airfoil are you use in this plane wing Clark-y or clark-z And which is better for noob rc pilot

[@AndrewNewton]

Probably a slimmer Clark Z, maybe 9% chord thickness. But it really makes very little difference with slow flying models. A wing with no airfoil will still fly.

[@espr7564]

That's a nice plane well done 👍

About 650mm from memory, but you could use the full 82mm arrow shaft length. Link to plans and more detail in the description. Have a look at this one too kzbin.info/www/bejne/j4GQqa2uetV5Zrc

[@daduvlogs4831]

Hello. How much weight for plane. including battery

[@AndrewNewton]

You know where to look

[@carlossanchez5600]

One more question, could I use a 7 " X 4.5 " standard prop. (Puller), turn it around and make it a pusher changing the motor rotation? Thanks in advance

[@AndrewNewton]

Carlos Sanchez Yes Carlos, that is the correct way to do it. Just have to make sure the numbers on the prop are facing towards the nose. There is no need to buy a "pusher" prop.

[@foamaxmore]

Nice demo thank you

[@juli23us]

That looks like a good plane as you said. How exactly did you make your ruder hinge? Did you just use the packing tape as a hinge or did you use small hinges to connect your ruder to the vertical stabilizer? Where should be the plane's centre of gravity? I guess where the wing is the thickest? Thanks for any help :) Btw you do great videos!

[@AndrewNewton]

Thanks Julias. Just packing tape hinges on all my planes, nothing fancy. They work well. CG is usually at the thickest part of the wing but some testing may be required. Somewhere between 20% and 40% back, just have to fly it and see.

[@LWJCarroll]

Hi Andrew, do you still have the SketchUp file available?? The link doesn't work now.... the "photo" of the fuze is missing a dim at the front of the nose...402mm plus ???? to the nose cone part....I am getting the parts together to make one etc Thanks Laurie
