Ned Stojadinovic commented on Chris Anderson's blog post Simple transitioning quadcopter VTOL tailsitter
"Hi Peter. I have been working on much the same thing.

I think I have a solution to the take off transition that should work for you - and I could do with some advice on the FC firmware. Please drop me a PM if you would like to discuss"

I notice that a lot of UAVs out there have generous amounts of dihedral, to the point that they look like the old fashioned "free flight" models of yesteryear.But UAVs are not free flight models, nor are they full sized aircraft or models of same.…

Ned Stojadinovic commented on Eli Cohen's blog post Maiden flight of world's largest 3d printed plane
"Well argued, sir.
The aim of this site is to exchange information (obviously), but I think that the ultimate goal is to exchange and propagate ideas, and so it is good to see a logical presentation of your reasoning for doing what your doing.…"

Ned Stojadinovic commented on Eli Cohen's blog post Maiden flight of world's largest 3d printed plane
"I think the trick is to use the technology where it's appropriate. ATM it's really slow and the strength is not exactly up to carbon fiber atandards, so it's great for prototypes but perhaps not so good for mass production."

"Hi Stephen, As luck would have it, I moved from Canberra just as I heard of your group! I think however that I can help you with designing and building the sort airframe and launch/recovery hardware that you'll be needing. Please feel free to drop…"

"I did indeed, though I still have the original!
It seems that people want custom designs and I'm good with that sort of thing. I can't show any photos of work that I've done for other people, but if you want an all terrain electric or gasoline…"

"After a bit of work, I can tell you that to ship from our location (near Byron Bay) to Epping 2121 is about $98. Other places around Australia would be proportional."

"Oh yes, servo design. I recommend that anyone contemplating such a thing should read a series of excellent articles:

Otherwise, the motors (worm drive is generally the go) are…"

"Delivery in Australia won't be too much. I've had a lot of experience shipping old engines and those things are serious heavy but shipping was very reasonable. Mark, I'll get you a quote ASAP - I've been away in a place that didn't have WiFi. True…"

"For those interested in shipping costs, I have a funny story relating to the fact that everybody wants to import stuff INTO Australia. It really throws agents off their game if you ask for a price to EXport an item - you have to imagine frantic…"

I can ship them anywhere using the usual services like Fedex, UPS, TNT, etc. I will get a list of prices to various destinations ASAP.…"

"The motor power is about 400W, they are made for reliability and low noise rather than all out power. Still, they have huge torque and the rover will effortlessly climb until the wheels lose traction."

Ned Stojadinovic commented on Stefan Gofferje's blog post "Warning of RC-Timer" or "Why you shouldn't buy from far east cloners"
"A couple of issues, if you please.
First of all, components from other suppliers are not "clones". The designs are developed by the community and consequently belong to the community. Anybody is free to build their own versions or else throw their…"

Say you wanted to build a glider to do the usual glider things. How big would you make it?Given that fuel load is not an issue, and the mass of the APM is insignificant, would you make the wingspan 1.5 meters or 3.5 meters? Or bigger than full…
