"Thanks Gary,

Now I have some companies to examine. 
If it isn't about the sensors, but rather the firmware, perhaps I can improve things.  I have been programming computers for over three decades, and that experience includes some embedded systems…"

"Thanks Gary,

I had no idea he'd made junk. I was just astonished that he'd obtained a flight time of over two hours.  I'd have thought that to get such a result, he'd have spent a fortune on really good components, as well as a lot of time…"

"Thanks Gary,

I appreciate all these links.

BTW: My Blade 200 QX finally arrived today.  Silly me, I did not order a transmitter for it when I ordered the quad itself, so that is ordered now, and will arrive probably Monday or Tuesday (I found a…"

"Thanks Gary,

Is it necessarily true that 3D printed frames are too heavy and flexible, or might that be an artifact of the primitive state of the technology at the moment?  Is it not possible to use such a technology to print carbon fiber or nylon…"

"Thanks Gary,

This is gold.

What you say is not much of a surprise.  It seemed to me that since so many quads available no have such short flight times, it must be hard to do.This is precisely WHY I want to do it.  ;-)  If it was easy, everyone…"

"Hi David,

So, I would infer that the benefit, or disadvantage, of the 3x blade GF5030 depends on the capability of the motor.  The chap who advised the use of the 2X GF5030 reported that it significantly improved the performance of his Blade 200…"

"Hi David,

Thanks.

You want to check on the links you provided in that blog, as those for the propellers are broken. But, had you considered something like the Genfam GF 5030 3 blade propeller (or printing your own 3 or 4 blade propeller -…"

"Thanks

What size battery does not have this problem?  Or does it apply to all LiPo batteries?

I guess, from what has been said so far, I am looking for a flying battery, with some number of light motors that turn relatively slowly and that have…"

"Hi Gary,

Thanks.

I don't suppose that there is a tutorial on how to use that page you have the link to: especially with regard to where I find the data to enter into it.  I ask half in jest.  I am sure I can figure it out, but I am not sure where…"

"Thanks Ben

OK, then, I assume that LiPo batteries that provide a lot more energy will also weigh more, and thus, for a given set of motors, may be counter productive.  So what, then, is the trick to get longer flights?  More powerful motors along…"

"Yes, yes, and yes.

The flight conditions and profiles were identical, and I charged the batteries fully.

I repeated the tests today, in identical conditions, with the same results.

A subjective impression (since I do not have any means of…"

"Hi Johann,

I am brand new to this forum, so you'll have to explain how I send a friend invite.

I fully expect that initially the parts I make will leave MUCH to be desired; but that is the fun of trying: to learn to improve to the point where you…"

"Thanks Johan,

That is quite helpful.I guess something that would be useful would be a good introductory book.  Not something like 3D printing for dummies, but rather something like the books I have just bought that introduce me to robotics using…"

"It seems there is little activity involving really tiny multicopters, even though companies like Hubsan, WL and Walkera seem to sell a decent quantity of them.  Or maybe those that frequent this forum are more interested in larger multirotor…"
