Hi everyone,

I'm creating this thread to share your drone/copter information. I believe, this would help immensely for newbies like me during the initial build. For example, the Chris's blog on cheap Hobby King quad configuration is really a good resource.  

I don't want to burden anyone who is willing to share their info. Hence all fields are optional. Atleast the first 5 fields are ideal. Please find the list of fields to copy/paste at the end, so you can start filling :-). 

Here goes information about my quad.

battery:  4S 3300mAh (Turnigy nano-tech)

I'll start off..

frame: My own hexa creation

controller/autopilot: APM1

motors: 2836 880kv (3DRobotics)

esc: 25A (Turnigy Basic)

propellers: 12x47,  (Found a distributor and order 30 at a time)

battery:  3S 5000mAh (Turnigy nano-tech--45-90C... 6 motors draw way more amps..I messed up my 3S 6000 25-50C pack) flying time: ~9Min. 9 Min Flight

radio: Turnigy 9X

video/osd: GoPro/none other: Sonar, Xbee, GPS/Mag, 

Misc:

My latest frame, named Firefly Mark One, is a 3D printed multirotor.  See the flight video in my blog.

Here's BoM for major components used:

4 x FC 28-22 Brushless Outrunner 1200kv  $6.99 each

4 x Common Trex 450 tail booms (12mm)   $4.95 for 5 booms on ebay
2 x Bags of M3x20mm hex bolts $1.99 each
1 x Bag of M3 nuts $1.76

Hi Elison,

Are you using the 8x4 props now? (hope the HK order has arrived now, me too waiting for an order :)) 

What is the flying time of this? and payload?

thanks,

Ruwan.

Yes, they were the 8040 from HK, but I broken on blade on my very first flight, so I had to switch over to the 9x5 which is almost equivalent, but not as cool looking.  I haven't weighed it, since  I don't have a scale that can weight over 1.0kg.  But, estimation from the individual components, is about 1.2 kg, without the battery.

Add the weight of the battery, which is 230g.  I'd say the flying weight is about 1.5kg or so. I can fly about 10 minutes, before I start noticing any drop in power.

The motors are really too large for this little frame, which I originally plan to be a mini, as you can see from my blog.  I'm waiting for some replacement motors before I can put my 3D printed arms on it and fly in mini configuration.  But, I was chomping at the bit, waiting, and wanted to get flying.  With these motors and props, there's a lot of lift and thrust, so I actually had to dial down the STAB P values to keep it more tame.  In this configuration, it would be a great outdoor flyer, but it's winter here in Canada, so I'm just flying indoors.

.

10 minutes sounds good. Yup, i was following your blog. 

Using a custom home built frame, I'm trying to build one for indoor use, unfortunately I'm having 4S LiPos (309g), so I won't be able to use these motors. May be this will do. 

Would your original configuration (Mark One, with 2S battery etc..) could carry a payload say 200g? Could that also give you 10min? 

I also need an indoor mini quad, need to carry 200g payload, have atleast 20min flight time :) am I expecting too much? :D playing with eCalc now..!

regards,

Ruwan.

Hey Ruwan, I don't think that motor can handle 4S, KV is even higher than the 28-22 that I'm using.  It'll surely burn up.

Unfortunately, with a 4S, you're really limited to lower KV higher torque motors, and larger props.  Have a look at this DT850.

For my mini quad, I'm using the 2200kv micros, and I found a great deal on ebay for 6x3 3 blade props on ebay, and they have both counter and clockwise rotating:

Clockwise: http://www.ebay.com/itm/150634444109?ssPageName=STRK:MEWNX:IT&_...

CCW: http://www.ebay.com/itm/160622941398?ssPageName=STRK:MEWNX:IT&_...

The 3 blades are less efficient, so I'd expect less flight time, and I have a set of 7" 2 blades to compare with.  The space saving is better for my mini frame, and I just think the 3 blades are so much cooler.  I also have a small 3s battery coming with the motors, so I can drive those 2200kv motors a little faster than the 2s.  This will generate more power with smaller blades, in case the 6" blades don't give enough lift.

I find that the ecalc will give you some estimates, but really need to have it built to really know what the flight time is going to be.  If the 2s batteries are able to drive the motors and props fast enough to provide lift, I think I should get the 10 mins of flight out of it.

Thanks, this really helps.

The propellers are 8" right? 

A quick browsing showed me a nice protector for the quad, http://www.rcdude.com/servlet/the-1886/Gaui-330X-Protection-Frame/D... Hoping to either build one or buy one. 

regards,

Ruwan.
