I have moongel on there too so its silky smooth.

Weight wise she is starting to feel a little porky, all up weight is something like 540g but I have some 5x4 props coming which on these motors put out about 439g of thrust so that is a total estimated thrust of 1750g, so within the 3:1 ratio but how the motors handle that weight and the speed at which they can spin up the prop will play a factor in how the quad responds. we will see though.

Cool not bad

I think I may go for one

Cheers. Time to start casually browsing for a 250 to build as a side project from remnants of the iFly.

Doo it

My new soldered Naze32 and the wire came this morning

Are any of you using Naze cases? weather it be purchased or DIY cover or protection for the naze circuit board?

What's the Max rated motors people use on the 250s? Just wondering as I've got 6 "2215" spare after having an accident with the iFly4.

2215 are generally going to be a little heavy for a 250 quad. What Kv are they? I would imagine a 2215 motor is going to be around 50 or 60g in weight and really better for spinning 9" or 10" props.

For a 250 sized quad you should be looking at 1806/2204 or at a push 2208 sized motors with a kv rating of around 2000-2300.

Got one, not used it yet. it will go on my hexa at some point soonish. Would help keep damp out but the FC is not overly exposed I think to other damage unless it gets clipped by a broken prop...

According to the blurb, they are KV850.
Since ive 6 of these motors, may look at a Y6 instead

gandhi · 4 Mar 2015 at 11:42

Yeah, you're gonna be wanting largeish props to get much thrust out of those I think then.

Y6 would be fun!

the motors will take 1045/1147/8045 props, so the 1147 should lift one.

TL; DR I've been trying to add a camera to my helicopter but it isn't quite working, spec me a <£50 "-copter" of some kind...

I dug out my £12 camera and mounted it to my €15 helicopter, which came out surprisingly elegantly but came in at 22g including the 14g camera (the helicopter itself weights 42g).

So I put the helicopter on a diet and the superleggera version came out a whole six grams (14%) lighter, and looked like this:

It still isn't great so I might get an indoor/cheap quadcopter of some kind- any ideas for £50?

DJMK4 · 4 Mar 2015 at 18:55

Just had to extend 2 x ESCs power wires so I can solder the power on, they are ok, but also had to expend the motor wires

Last time I am cutting wires "short"

The motor wires are also not soldered to the escs, just meshed together with some leccy tape, no soldering until 100% confirmation the motors spin right direction

Whats the bare minimum I have to put in place now to test motor directions?

FC and reciever? (and battery?)

gandhi · 4 Mar 2015 at 19:10

Yep, just those things.

DJMK4 · 4 Mar 2015 at 19:27

Got the breakout cable plugged in, 3 of the wires go back to my RX, then plugged the ESC connectors to the board, pin 3 and 4 jumpered on the RX

Just watching a few youtube videos on the set-up of the taranis for CPPM

Am i supposed to be delivering power to the Naze somehow? by these battery pins? do I need pins that go here the same terminals my battery cable comes off with XT60? a wiring guide I found didnt mention this, but youtube videos are showing this in use

Kanifee · 4 Mar 2015 at 19:38

breakout cable supply's the esc with power, the esc 3 pin connection to the naze supply's the 5v it needs.

ONLY CONNECT THE BEC OF THE ESC TO THE NAZE AND DOUBLE CHECK ORIENTATION OF THE CONNECTION.

Not quite sure I understand this, basically the ESC comes with a 3 pin connector

(Brown = Neg)
(Red = Positive)
(Yellow = Signal)

I have connected each of 3 pin connectors (so from all 4 ESCS) to the corrisponding motor pin rows on the Naze

Basically following this guide, mine looks exactly the same as this

Is this ok? this should give me power ? and not blow anything up?

Kanifee · 4 Mar 2015 at 19:47

That's perfect.

DJMK4 · 4 Mar 2015 at 19:50

Cool, better get the radio programmed and get her plugged in to test then

Naze32 flashed, identified two motors that need switching, now I can look at soldering these in properly.

Was going to upgrade firmware on the FrSky D4R but need a USB convertor so it seems so will skip that for the time being

Kanifee · 4 Mar 2015 at 21:15

My first full session in Acro mode, didn't even hit the panic button/flight mode switch once. Quite happy with it considering it is something like the 4th time I have actually tried acro mode and previously was never for any extended period of time. Time spent on the simulator has helped a heap!

The video is unedited so I do apologise in advance, couple of moments when I hit the deck and nothing happens for a short while.
I have upped my yaw rate on the naze to 0.45 though I think I am going to put it up to 0.6 and increased RC rate to 100. The wind is still a bit too much at the moment but it is the best it has been for at least a week and the quad is feeling heavy.
Still waiting on the 5x4 props though I am toying with the idea of a lightweight cheap acro quad on a little x frame but at the same time I really want a plane to fly in this massive open field just feet from my door, will have to see what wins out

Cool video

nice flying and decent quality video.

Not had a chance to read up on the different flight modes yet, although whats a good stable starter more to use? Will have to read up on it more tomorow, the only thing iv done in the base flight software so far is

CLI enable ppm
CLI enable tele

Test motors to find direction

Update naze firmware

Need to learn how to configure the rest of it and learn modes etc

I created a new model on the taranis and bonded to RX. Setup mixers but not had any stick movements activate anything yet

Will continue tomorrow after revision

Kanifee · 5 Mar 2015 at 06:02

Angle mode, basically the craft will not bank past a certain angle and when you let go of the sticks the craft levels out by it's self, this is the most beginner friendly mode.

horizon mode, the craft will still auto level when you release the sticks but if you push the sticks to the limits the craft is not locked to an angle and will roll or pitch until you release the stick meaning it will go upside down.

Acro mode, input a movement on the sticks and let go and the craft will hold its angle in any direction and will continue moving, will flip and will only combat outside forces like wind depending on how aggressively the PID's are tuned.

you have a toggle option to switch between angle and horizon, when neither are selected it auto's to acro mode.

Other settings I would enable are stop the motors spooling up when activated, enable frsky telemetry and battery voltage monitoring.

You will also need to set the channel order for your TX, mine is TAER1234, yours from doing a quick google is the same. The command in the cli page is MAP TAER1234
You have basically told the naze32 that your transmitter order is channel 1:Throttle, 2:Aileron(roll), 3:Elevator(pitch), 4:Rudder(yaw), 5:switch 1, 6:switch 2, 7:switch 3, 8 switch 4. To enable switches I had to program my transmitter to enable each switch on a channel, assign a voice response to a switch (optional) and then assign a function to that switch on the naze yours may already be active though.

you then need to enable the telemetry on the TX to be form the FRSKYHUB, you have a 2 pin servo lead coming form your power harness to the naze's telemetry pin in the centre of the board. BE CAREFUL AS POLARITY OF THIS CONNECTION IS CRUCIEL AS I AND RILOT FOUND OUT, THE CIRCUIT HAS NO VOLTAGE POLARITY PROTECTION, PLUG IT IN BACKWARDS AND IT WILL FRY YOUR NAZE.
Im afraid that's all I can realy help with as your transmitter may be completely different to mine int he menu system. I want a terranis but my 9xr pro is doing fine for now so that will wait.

May I ask what function CLI Enable Tale serves? I don't think I have enabled that or seen it on any of the guides, I may be wrong though?

DJMK4 · 5 Mar 2015 at 07:02

Thanks for the details

will have a good read when Iv woken,but it seems angle is the one to start off with

Enable Tele cab be entered as shortened version of (sorry the post above was a strange autocorrect)

Enable Telemetry

Sorry coming from a cli background like cisco you can enter half the word and most cases if recognises it, seems this does too

It tells the naze to start outputting Telemetry to rx if you have it wired in, I don't yet but thought I would get it enabled

Rilot · 5 Mar 2015 at 07:26

You may have to flash the D4R-II. I'm not sure whether the stock firmware can output 8 channels via PPM. I think they come with 4 enabled and need the flash to get all 8. I had to flash mine but it was an older item.

Flew my Diatone in the living room yesterday just to get it stable in a hover. Had to push P a bit but I and D were fairly close as stock. Got a little wobble after stick movements so will up I a bit more.

And yeah, don't get that V sense the wrong way round. I learned that the hard way.

Kanifee · 5 Mar 2015 at 07:29

I really need to focus on dialling in my pids, just don't like taking a laptop out in the field with me.

My d4r-II came with the 27ms firmware already flashed and outputting 8 channels so you may be fine DJ,
