@jeremy-wilkins that is what I would do unless it’s fairly obvious what the airfoil is. If you take the Akromaster (thread elsewhere on this forum) I ...

@leccyflyer I would also strongly recommend an air extract system, as I’ve outlined above. Not only does this vent to the outside air but it draws the...

@leccyflyer If you think about it Brian, burnt toast will trigger a smoke detector so the laser cutter will almost certainly do the same!

Hi Brian. The simple answer is yes, laser cutting can produce a lot of smoke! The amount produced when I cut 20mm EVA foam is quite considerable and n...

There was a very sharp eyed attendee who spotted that I hadn't made the tip airfoil section parallel to the other ribs and this was because I made a m...

@jeremy-wilkins that was my thoughts when I originally started posting about it, it caters for my (limited) modelling needs.

@jeremy-wilkins I think you have to weigh it up, how much are you going to use the software. For example, I have looked at a lot of software developed...

@jeremy-wilkins unfortunately that is the way of the software world, they want you on a subscription basis rather than paying out for the software. It...

@jeremy-wilkins yes if you try it from within Reader it will try and make you buy the full version!

@jeremy-wilkins Adobe have a free on-line converter No problem taking a screen shot of the part (s) that you want, I usually select what I want fr...

Personally I wouldn't do that unless it's only part of a drawing that you want, I would convert the whole thing into a JPG then import that as per my ...

@jeremy-wilkins Fusion 360 cannot open PDF files, they have to be converted to another type of image file, usually JPG. Do that then trace around the ...

If you just want to work with the PDF in Fusion 360, say to trace over the image then just convert the PDF to JPG. Converting most PDFs to DXFs has no...

@jono D box wing design is the way to go. You would do away with the 2 forward spars and end up with a stronger, albeit slightly heavier, wing.

Phoebe in the latest RCM&E looks like a very suitable candidate, designed to be made from, mainly, Depron with a Kline Fogelman airfoil.
