im encouraged to hear this, was just thinking last nite on how to build a Y6 with all the motors on top, and if overlapping prop disc's works, thats just fantastic

Yep, i would agree with that, in fact if making a bicopter its the only way to achieve decent control, like balancing a broomstick vertically on your finger

a quick and dirty calculation http://multirotor.files.wordpress.com/2011/03/multirotorcalc1.xls (based on 170 watts per kg to hover - good multis hover at 120-140) and 80 % battery capacity 1750 grams ( frame = 1388 grams battery = 362 grams) has a flight time of 7 minutes and 10 seconds (at...

Stack - looking at 7 day forecast Wednesday is fine, then it goes downhill again

Check your magnetometer - that was the issue on my ardupilot, it was out by about 5 deg

@totality - 3.7 is about 20% capacity So yes, if you are putting 1400 back in you haven't quite used half, so 7-8 minutes would be finr

What does it weigh? Can give you a rough idea when I know the weight. 3.8 volts - is that under load? I fly until about 3.75 per cell unloaded, which is prob 3.4 under load (flying) sounds like you are only using 50% of the capacity, you can safely go to 70-80% or about 7-8 minutes ( without...

great comparison between the three angles, at least the props are still there for reference. Stacky - yea it was you who sugested a slight down angle to me, so im going to try 10 deg

I'm about to mount mine to my tricopter, it has a 140 deg lens, contemplating mounting it above and to the right of the rear arm, so that both front props will be in view, and have it angled down about 10 deg, will let you know if it works. Camera work is done by a seperate go-pro, which is in...

I can only comment on batteries - use turnigy exclusively for last 3 years, brought about 30, had 1 faulty when it arrived (cell voltage =0) managed to bring it back from the dead, but its not a good performer, they rest have been fine. pushing them near their C rating, they get quite warm, but...

Hi Anthony keep a watch here http://www.openpilot.org/openpilot-production-status/ hopefully not to far away

I steal the wife's nail polish, does the trick

@J3Cub - i like photo #2 , next time smile :)

Well done Iris, Congrats - mine was photo #2

you know me, mr budget ! :) 15 hrs is 112 flights, so good info to know, thanks Pete

i figured a set of 4 cheap props ($2 each)every 20 flights to be safe, if i use something more spendy, say APC at $7 each, then maybe 60 flights, but the cost will be similar. need to have a safe flight time within which they will be swapped before failure. problem is, can anyone tell me what...

Have an interesting scenario developing, there is a chance in my current day job, to bring some inspection work by multicopter into play, and i need to work out what the cost per flight is, the final figure blows me away I worked it out like this, based on a lightweight quad, running a gopro...

hey bart, maybe you should do a quick mailout to the forum members, in case this thread drops off the "new posts" list ?

been flying (well, avoiding the ground) for 14 months now, and finally in the last few weeks have actually attempted to take some photos (the photo higher gimbal giveaway set me off) The only camera I am using is a gorpro hero hd (series one) and have gotten used to the wide angle, as it...

i have always hard mounted mine, only had an issue with vibrations when i had a bent shaft or badly out of balance prop. That camo foil is cool :-)
