Love the simplicity of the way you get the message across ..."I love airfoils. Just love the smooth curves that produce magical lift..." This is your quote not mine from your previous video !!! And I couldn't agree more. I have been tied up within the aircraft industry nearly all my working life.... I'm now an old grotchety at 64 ... and yes it still fascinates me. I've been fortunate enough especially in the last 20 years or so to even teach on that very subject often in all manner of exotic locations all around the world .. LIFT vs WEIGHT and THRUST vs DRAG and yep still gets me in ... all just differential air pressure over the wings chord ... :-) so just explain to me again how does that 400 tone aircraft get up in the air ... amazing!, love it!

Please show how you'd do a tapered wing where you have both a reduction in chord and relative chord height. My concern is that the wire will be moving slower at the tip end and faster at the root. Won't the slowness of the tip end wire cause the foam to overly melt while the speed through the root end is just right ?? Guess a LOT of trial and error will be involved. LOL. But I think it's doable.

Don't have to do straight wings. Don't have to have the same airfoil shape at both ends. With different templates and/or sizes at each end the shape will smoothly transition from one to the other. Can even put a bit of twist in the wing. The Wright brothers twisted the tips of their Flyer wings slightly downward to give them better stall performance. When the middle stalled the ends weren't yet in stall.

Great stuff, got a lot of info from your video's and going into serious efforts myself. For my first project (which pushed me to hotwire technique fast ) I wanted to combine a scratch built delta wing with the fuselage of a Lidl XL glider. i got some good templates but i was wondering if the foam could be cut evenly and not heat up to much at the tip? Caus the travel is a lot larger on the inner side of the wing then the outer so i wonder if the foam would hold up the longer wire cutting time on the tip in comparison to the normal wire cutting time at the base rib . I hope it makes sence what i am trying to say ;)

Yes, but the foam would need lots of reinforcement

Is there much of an advantage moving to a 4s lipo over the 3s you used in the previous video?
@AndrewNewton
@AndrewNewton 9 жыл бұрын
+stephen clark Oh yes, big advantage. Especially for the 750mm wing halves. Hotter wire = Faster cutting speed = smoother cut. 3S was OK but slow, 6S (2 x 3S) was too hot and burned out the wire. 4S is perfect.

+Andrew Newton nice job, you make it look easy! I have used a BRUSHED speed controller to adjust the heat to the wire. works great,

Andrew Newton I'm designing an ultralight currently--among my other 1,000 projects. 😅 I'm using the Clark Y as well. ☺️

Hi Andrew, thanks for a great video and the aussie links too :) Your link to your video about your hotwire setup is broken. Is that video still available ?

+Andrew Newton Brilliant Andrew, thanks. I was going to start scratch building here in Melbourne using foam board but it is more hassle than I realised here. I like your wing method and will give it a go. Maybe I'll need to use the foam board for the fuselage. What do you use? Darren

I know that foam :) I was looking at the other day at Bunnings wondering how I could use it. Now I know ! Gotta give this a go. Thanks again.

Hi Andrew, Can I ask you a question. I am buying a 3in1 Soldering/Rework station which has variable DC output. There appears to be several versions though, 1amp, 2amp, 3amp, etc. For hotwire cutting, 1A would be sufficient, right?

4A.. I was planning on just using guitar wire..that should be OK right. I could use an old computer power supply I have. some good amps there.. lol

Yes the thinnest string is the one to use I believe. There are plenty of tutorials on adapting a PC power supply, but I managed to trip the house safety switch when I tried. So I now have a proper adjustable unit.3S and 4S Lipo batteries work fine too.
