Justin Martin commented on Doug Hunsaker's blog post How to avoid pitfalls when using taper and twist
"Doug great video series. May I point out that these are very simple concepts, and as soon as you design a complex wing with more than one foil, much of this becomes a different story. For example, typically a high performance aircraft will have the…"

"Patrick, welcome to DIYD! May I ask the benefits of your (purchasable) product over say Dr Drela's free xfoil and xflr5 programs? Gary, just to play devils advocate here, but maybe a good discussion point would be the use of flying wings in…"

"These things are great! I bought my first one for fun, and quickly figured out how great thy are for my dogs. They love chasing it! I have managed to break 4 of them, but have also abused them more than most. They are caught and chewed about 3-4…"

Justin Martin replied to Dave Shrader's discussion Gas Hybrid Quad Rotor UAV?
"Awesome job troy! The question wasn't whether it could be done or not. It had been done, and we have seen it. Instead the question is of practicality. Is it more efficient than one gad engine mechanically linked to 4 Variable Pitch props? Is…"

Justin Martin commented on Andrew Rabbitt's blog post Wing lift distribution presentation
"Andrew, I think we are agreeing on most points. In regards to the poat, you, yourself, brought It to my attention that I essentially got off topic and went on to discuss matters in design that are completely unrelated, and did so in length! You…"

Justin Martin commented on Andrew Rabbitt's blog post Wing lift distribution presentation
"I guess in a way it could be misconstrued as some kind of rant... In reality all I was getting at is that prandtl's lift distribution theory was accepted and proven over the years several times by several individuals, including Nasa. Mr Bower…"

"Andrew, you are totally right in regards to reynolds numbers, and the world as we know it falling apart at low Re's.  That being said, I believe my statement is 100% accurate, in that if wingspan is not a constraint, it will always be…"

Justin Martin commented on Katrina Rosen's blog post Nice article in Gizmag reporting on Krossblade's SkyProwler
"Edit: Keep in mind that the comparison you might have seen may not have been entirely fair for the aircraft involved. As mentioned, the foil has to be chosen specifically for the parameters. Weight of the aircraft plays a huge role, and if it were a…"
