"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…"

Justin Martin commented on Patrick Hanley's blog post Airfoil Analysis
"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 the…"

Justin Martin commented on Blucraft's blog post Introducing CloudFoil: Full airfoil CFD simulations in the cloud
"To add to Martin's comment, I would also like to see many other polars, to include the infamous RG15 that is widely used both in the UAV, and high performance sailplane world."

Justin Martin commented on NIck Dr's blog post Cheerson CX 10 - Surprising build quality!
"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 it…"

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 and…"

Justin Martin commented on Luke's blog post How to Program 6 Flight Modes for ArdupilotMega - JR 9303 Example
"This works great. One request however. I would like to program a safety switch. By this I mean if I activate the safety switch, it goes straight to manual no matter what. This will come in handy when having to deal with numerous switch combinations.…"

Justin Martin commented on Gary Mortimer's blog post FAA to announce new rules for sUAS, today Sunday (yes sunday)
"Trust me, I totally agree. In Fact, the commercial operators are already the safest as they currently are, and regulation will do nothing for safety when you factor in the numerous hobbyists who fly irresponsibly near airports, etc. However, at the…"

Justin Martin commented on Chris Anderson's blog post Analysis of leaked FAA rulemaking preview
"It is probably an entirely different level of security and background check. For example, a Top Secret cost several hundreds of thousands of dollars."

Justin Martin commented on Gary Mortimer's blog post FAA to announce new rules for sUAS, today Sunday (yes sunday)
"Guys, I think some of us are over reacting. They basically said that operating for hobby uses ] (Remote Control), then this regulation does NOTHING to you.All this does is provide an easily accessible commercial opportunity. I think a lot of us are…"

"I couldn't disagree any more DG, in fact I personally sent my own proposals to FAA representatives that were more strict for Comercial use. If any ing at all, this is showing light at the end of the tunnel, and it seems to be a positive outlook as…"
