Does anyone know the correlation between hovering time, flight time, and battery life on a copter? How much of the battery will be used just to hover and how much is used to to fly over a distance?
Thank you!

I noticed this too.
In my defence, I only got involved because Bradley was posting here! :)
And... your avatar is freakin me out man!
Kate, is this your first UAV?
If it is, I would not deter you from building your Hex, but while you do it, I would suggest acquiring something that bounces, because you will crash. And crash. And crash again.
Getting stick time on a cheap toy as you build your Hex, will save you hundreds (or more) when you do fly your hex. I'm old and slow to learn so it took me awhile, but it suddenly just clicks, and when it does, you can fly orbits and figure 8's around trees. Google massiverc or banggood for some cheap ones.
Hi Bill,
I've heard the same about starting with a simpler copter from reading other discussions and websites... unfortunately (as a summer intern) my mentors are set on building a hex, unless proven to be less efficient than another solution. I'll take into account what you said about all the crashing... we are hoping to do more automatic flights than manual so hopefully that will help! I'll also talk to them about purchasing one of the smaller toys you have suggested. Probably safer to start with.
Thank you so much!
Generally speaking hexes will be less efficient than quads. This is because quads can fit larger size propellers for any given frame size, and that is where you get efficiency (propeller area per mass).
Just draw some stick figure machines. Draw a quad with 10" props almost touching. Connect the motors with sticks. The total length of those sticks will roughly represent your frame weight.
Now draw a hex with 10" props almost touching. Connect the motors with sticks. The total stick length is relative to what the frame weight will be.
Now for both cases, divide your disk area, but your stick length. You'll see that the quad is higher.
Craig,
This looks awesome, one of the highest payloads I've seen so far. I think this is something we would like to use somewhere in the future for sure... just for testing purposes though I think they want to spend a bit less than that. Thanks again!

Hi Kate at one time I had a "Start Here" page on the DIYDrones Wiki, but it has been removed by those in charge because it doesn't fit with their view that it needs to only pertain to APM or Pixhawk.
If you are actually new to this and need to learn how to fly a multicopter I strongly urge you to take a look at the page I have reconstructed on my own web site at Drones Are Fun .Com
If you heed the advice there I guarantee you it will save you a lot of time and money.
And it even includes actual flight instruction.

I didn't know that 3DR and the person now in charge of the copter wiki section had removed it until I just looked for it to give you a link to it.
I am saddened by the fact that they have done this and am sure it represents a material loss to the DIYDrones community.
It does however make me very glad I left when I did.
Best Regards,
Gary
Gary,
That's unfortunate that it was removed :( This sounds very helpful and I'm looking into it right now! Thank you so much, I need all the help I can get!
That site is awesome!
My intro was from a different crowd: The: "Learn Acro First" or "We don't need no stinking leveling" people.
I suppose they thought they were being funny. I almost threw in the towel before I found a micro quad and learned how quads were meant to be flown.
Will definitely look into this, thanks!!
