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.

controller/autopilot: APM1
esc: 20A (3DRobotics)
motors: 850Kv (3DRobotics)
propellers: 10x47, APC (3DRobotics)

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

Could everybody please leave there config files or there Pids so that we can compare (and copy).

Yup, I also agree. Config files would help too.

Could you explain a bit about the APM mount? As I see, you've handled vibration issues.. 

regards,

Ruwan. 

care to share your eCalc experience here please? "using eCalc"  link: http://diydrones.com/forum/topics/using-ecalc?xg_source=activity  

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.

Sorry Ruwan for the late reply,

yes Vibration has been handled by fixing the APM to 1.0mm CF plates with giro tape and 3 nylon screws, then mounted to the Copter via 4 canopy washers on nylon standoffs.

I was very happy to get this frame at $42, and now that they are blowing them out at $29 (free shipping)!!! I have to say this is the best buy in the business.  They are very strong with properly designed spring loaded legs (this will save more damage than you can imagine).

The only flaw it the motor mount they supply - very flimsy, tends to vibrate a lot. I used 1/8"x3/4" aluminum to make new ones, and now the unit is extremely smooth and vibration free. I have had almost no flight time yet but so far it looks smooth with Stab_D =.06, R/P D =0, R/p P=.1

 

 

Hey again everyone, trust you are all well!

Here's a quick post of some of our new Quadcopter RTF kits we are building, powered by JetPax, an amazing frame made by them and build, tested and sold my us, SteadiDrone. Our website is soon to go live with these babies and also bigger octos and cinema octo rigs, much more to come!

About these frames. Custom moulded impact resistant enclosure, carbon fibre arms, moulded motor mounts, 30A ESC, 880kv 280w motors, APM1 + GPS, 6/9Ch Aurora 9 Radio, 2 x 4200mah 3S batteries and lipo charger. Pricing is still to be finilized but, the whole kit is around USD $ 2500 might sounds like a lot for some, but we're using some really good parts, it's super light and fast, can carry up to a kg easy and very strong, splash proof and will soon have extended landing gear for GoPros.

Let me know your comments.
