I tip my hat to you sir. You are indeed one of the artists of the RC scratch build world! You've shown some real originality in your builds! You, ExperimentalAirlines, Flitetest, and just a small handful of others contribute greatly to the hobby! I think that the sharing of building techniques, refinements, tips, & tricks benefit scratchbuilders the world over! I became interested in the RC hobby for the first time (at the ripe age of 66) after spending time with one of my grandsons. We bought a cheap Harbor Freight "Yellow Bee" plane then he got first crack at flying it. Very first try it broke a wing and he lost interest. I took it home, repaired it, studied up on the basics, then had success flying it later on. I am now hooked on this hobby and have done several successful scratchbuilds since then. I subbed to your channel and wish you the best. Will

[@RlainTheFirst]

Will Yam , Agreed! Except that I'm 26 with no grandkids yet. :)

[@zezoar]

is that carbon fiber you are cutting there? Its better to wear some breathing protection and also try to keep dust and chips contained (like sucking it away with a vaccum-cleaner)...just if you want to keep your lungs healthy of course (and that of your viewers...)

[@AndrewNewton]

Yes good points thanks. I do wear a mask but had not thought of vacuuming up the dust.

[@zezoar]

before i forget it: if using vaccuum you should use some industrial-grade vacuum with special (HEPA) filter or water/oil-filtration because normal-filters dont really work on carbon-fiber. if you use a normal filter: only use that filter for this pupose and don't clean any living room with that filter because it cant contain carbon-fiber residue. another possibility, which is more suitable for hobby-uses imo is to work under wet-conditions like using wet-grinding-paper, or try to wet the file and the carbon-rod so the water can bind the produced dust. Also its good to use some (wet) news-paper or sth to collect all the dust and grinding-residue onto, so you dont need a broom (which would only spread the carbon-dust into the air) sorry for my english i hope it's understandable :) anyways i love your videos and ideas, big thumbs up!

[@harveymorford1726]

Very practical and straightforward. Thanks for sharing Andrew!

[@AndrewNewton]

Will yam Dysinger Thanks for your very encouraging words Will. (BTW I can't reply directly to your comment, something to do with your Google Plus settings)

[@SladkaPritomnost]

Brilliant solution! Love this plane.

[@ziffa27]

Wow really well done ;)

[@anshuld90]

Brilliant,smart yet simple way to switch from regular wing to dihedral and vice versa, with least amount of work and time. Thanks for sharing!!

[@isleman44]

Thanks Andrew you have just inspired me to build my own Dihedral winged plane..

[@LINDANETA1]

NICE PLANE Andrew!!!

[@TheCANhunter]

Awesome Andrew! I love your videos!!!

[@biglon62]

Awesome idea thanks for sharing!!

[@mentalvmaxrider]

Very nicely done sir. Thank you for sharing

[@門徒解說聖經]

Andrew, thank you

[@RIYASmkd-g9d]

nice flying

[@GeorgeStephen1959]

Awesome and very easily done too, Andrew Newton

[@AndrewNewton]

George Stephen and very easy to whack a straight spar back in if the experiment doesn't work. But I tried it sloping yesterday and it flew like a dream, so smooth.

[@tonymac96]

Wow....I had this idea in my mind few days ago...about how to to do dihedral wing....after seen a good video from Experimental Airlines...I thought to use two tubing of aluminum for rigidity at the proper angle....but after seen you video...I think one is more than enough.... Very good work!!! Would like to see a photo of the dihedral wing over the fuselage...and how well the rubber band hold the wing in top without dancing... Thanks

[@AndrewNewton]

I did put small wedges of foam between the wing and fuselage to stop it rocking.

[@tonymac96]

Thanks!!!

[@NOXFPV]

Very cool. Great ideas in this video.

[@woodstoney]

You are fortunate to be able to fly in such a lovely area! Beautiful. Great job on the dihedral wing too! Thanks for sharing!

[@AndrewNewton]

Yes we do have lots of flying areas available, I'm only now understanding how lucky we are. Dihedral wing slope soaring video coming soon.

[@Mikinct]

Great video- What does this do adding this angle to the wing? Float easier- fly better?

[@AndrewNewton]

Nicer turns and a little bit of self levelling

[@Colaris99]

You seem spoilt for choice with open areas to fly in! :)

[@AndrewNewton]

Colaris Yes we do have lots of options when you include slope soaring sites as well as flat areas.

[@kanedewilde]

Awesome! What about using this technique in a flying wing?

[@hspeed3656]

Good day Andrew. Hope you have been out flying. Good to see your finger has been healing up nicely. How do you know what degree of angle for dihedral. is more better for higher wind or less? plane 1115 gr wing 1430x190 (includes ailerons) fuselage 920, Also on one of your other videos you modified there motor angle on a pusher, what is a good angle to start off with there as well. Sure liked those engine mounts that changed the mounting angle, very cool. I will use washers until I break down and get that 3d printer. Thanks in advance for all your knowledge sharing. Jeff

[@AndrewNewton]

From memory 6º is a good starting angle. Dihedral is best for light wind slow flying. Not useful in strong and turbulent wind.

[@hspeed3656]

@@AndrewNewton Thanks Andrew, so in windy condition ( like I've being having here for several days now 18km) very challenging for me to say the least. I might be better off with little to no dihedral Jeff

[@AndrewNewton]

Yes I discovered that with this plane. Much better with no dihedral in wind

[@hspeed3656]

@@AndrewNewton Yes, I had watch that and had to watch it again, build a second wing with no dihedral and much better control in the wind. Just taped together to join the 2 , love that idea.

[@NOXFPV]

Thanks

[@rcscratchfly]

Very nice

[@LWJCarroll]

Thats interesting as you are emulating full size sailplane wing joining...as well as making it easier to experiment...I was hoping you would comment on the difference in flying with the dihedral versus flat...??...Rgds...Laurie

[@AndrewNewton]

LWJCarroll Thanks Laurie. I haven't done a decent side by side comparison yet. Quick impressions with dihedral, it flies smoother with less input required. Aerobatic performance is slowed down. Decalage issues are amplified.

[@EnglishTurbines]

Nice one Andrew, I also like where the Ailerons servo feeds come out the Fuz, very novel. I suppose the advantage of the diahedral is that it will turn in a little better and slowly self right itself?... Oh, btw, I did my first FPV flight the other day on my AXN, I have a clip up...and my first fpv scratch build in Depron is nearing completion.....:)

[@AndrewNewton]

Yes, a little bit of dihedral calms down the flight characteristics, really need to re-test it slope soaring for a proper comparison. I suspect dihedral also exaggerates decalage issues for powered flight. If the leading edge is sitting up at all then adding dihedral will make the plane loop up under power, no matter where the CG is. This wing needed packing under the trailing edge to make it sit flat. Congratulations on the FPV flights and I'm looking forward to seeing your build.

[@MasboyRC]

I make similar model like yours, but i put twin props. Very fast and stable to fly sir 👍

[@AndrewNewton]

Oh wow, that sounds excellent

[@wingsmh27]

Transmitter joystick goes right ,right aileron goes up. I thing dihedral angle is more in wing if i reduce it it work fine. Or if with ailerons wing have a flat (without dihedral) it work. I try at this Sunday. I made many trainer plans. Now want to take next step that's wings with aileron's. I know im new in this hobby. Thanks Andrew.

[@AndrewNewton]

Oh yes that could be the problem. Good you see you are experimenting, you will learn quickly. Good luck.

[@Avirusmetal]

love the interchangeable motor or not.

[@rva1945]

A question, sir: the tube, once bent, is strong enough to provide structural strength to the wing? BTW nice job.

[@AndrewNewton]

Thanks. Depends on the strength of the tube of course. Mine was strong enough

[@Declan-pg8cg]

Wow, that flies beautifully. What motor and prop are you using on it?

[@AndrewNewton]

[@cynr100]

Love your work Andrew (and your workshop :-) ), thanks for sharing.

[@AndrewNewton]

Thanks. The poor cars never get into the garage.

[@anhtuanvidi]

Nice tip, and nice plane, thank you Andrew to share video

[@AndrewNewton]

+anhtuanvidi Glad you like it.

[@THEfromkentucky]

How much does that plane weigh all-up?

[@AndrewNewton]

+fromkentucky Might have been 750g all up. It's no longer with me.

[@muhammadajmal2380]

I think it is a glider plane because its c value is under 4

[@AndrewNewton]

What is the C value?

[@wordreet]

When I cut a carbon spar, I use a half round needle file and slowly rotate the spar as I file it. The file is obviously much finer than even a junior hacksaw, so there is no fraying of the carbon at the cut.

[@AndrewNewton]

Demel cut off disc works well too.

[@wordreet]

True, but speed never produced precision. LoL! Just a quote from an engineering forum. ;¬)

[@RenKnight347]

@@AndrewNewton The one downside to cutting carbon fiber is the fibers that are cut can be light enough to become airborne and it's really nasty stuff to breathe in. A vacuum hose placed near to the point of cutting and some good PPE should help to limit any of these health hazards. As always, I enjoy your quick remedies, solutions and videos. Thanks Andrew!

[@johnmarktamano8834]

im tempted to dabble into DIY airplane

[@AndrewNewton]

Lots of rewarding fun ahead

[@samin2012]

which tape was that you used to tape wings?

[@AndrewNewton]

Red packing tape, 50mm PPS brand. Transparent Scotch Tough Tape to join the wings

[@zmlchannel286]

I like this plane do you make plans

Great video - lots of tips!

[@AndrewNewton]

Tom Komada Thanks Tom.

[@wingsmh27]

Dihedral wing not working with ailerons Goes to one side

[@AndrewNewton]

Ailerons reversed?

[@wingsmh27]

Andrew Newton Setting are all good. I thing Dihedral angle is more so this error arise.

[@espr7564]

That all looks too tricky 😕

[@AndrewNewton]

You wont know until you try it, but the 3 channel is easier to build
