Hi,

Just got back in from work. ESC`s are all calibrated with min and max throttle. Just weight quad - 1077 grams. Think I need to increase the Kv of my motors. Would this also explain why its totally unstable?

Many thanks

Hi, I am running a quad with the following: rctimer 930Kv motors rctime 30A esc`s Paris V4 board with WM+, BMA180 I have calibrated my esc`s, set my mid, low, high trims. I currently have a 4000Mah 3 Cell Lipo, but it seems that my quad only want to lift off with almost full power. The battery only ...

Have you tried connecting the 2 "faulty" motors to the "working" motor outputs? eg if top left isnt working, but top right is - swap the leads to the esc`s and see if the motor responds - this will rule out the motors and esc`s.

Just what I need for my quad to fly correctly ! ????!!!

Hi, I got mine from here: http://www.ebay.co.uk/itm/Carbon-Fiber-Tube-3K-12mm-Diameter-Quadcopter-Multicopter-/150766369446?pt=UK_ToysGames_RadioControlled_JN&hash=item231a603aa6 I have ordered quite a few for spares from here. Takes a while to arrive, but cheap and cheerful. Iain

Daft question, but if I invert the motors will I need to change the prop/motor direction?

Camera position wont be an issue as I can put it either underneath or above on my frame.

Cheers

Must admit - have already tried 3 blade props, but I found them noisier than standard 2 blades. Had nothing but rain since my last post, so just waiting for the weather to clear. My motor prop setup is rctimer 930kv motors with 10x4.5 props, but i`ve ordered some 8 x 4.5 props to see if that makes a...

Hi, Got around to removing all the shielding on this board. You are correct in that the usb chip is a PL-2303.

Hopefully first flight this weekend. Arranged with local land owner to go to his site - barn owl nests and badger set. Will see what they make of my quad

Many thanks again. All sorted. What a difference the firmware makes.

Hi all, First proper test flight today. The others I have done have resulted in various damage to my quad. Tied my quad to a brick this time Initial lift off results in my quad yawing left all the time. Other than altering the trim on my transmitter is there another way I can zero this? Currently us...

Many thanks for all the help. Will I need to recalibrate the ESC's once I've flashed them?

Micro clips arrived today. Going to have a go tomorrow.

Hi,

Many thanks for the reply. I currently have the r-timer esc`s and it seems these can be flashed as well. I might invest in the HK type and see what happens. Prop wise - i`m currently using 10x4.5 props and my motors are 930Kv.

Hi,

I am building a quad for wildlife photography/videography. I am currently using outrunner motors, but i was wondering if there were any quieter motors available to use?

Many thanks in advance.

Connect your wmp to the d12 line and see what happens. If you are not planning to add a barometer, then you will be ok using this line to power your wmp and nunchuck.

Iain

Hi Alex,

Both my wmp and my nunchuck are clones. To be truthful I powered both through the +5v line originally, but I have since added a BMP085, so I needed to move them to the +3.3v line. Both configurations worked without any issues at all, no freezing.

Iain

refractions

Hi,

I have the Paris V4 board, and i am powering my wmp from the +3.3v line and am using software pullups without any issues. Have you tried just the wmp or the nunchuck on its own?

Iain

Forgot to say - have you set your max/min throttle with your esc`s?

refractions

Using 1.9 - works fine with windows 7 64 bit

refractions

Have you set default PID levels?

I used these ones.

refractions

Have you set the min and max throttle on your esc's?

refractions

My xmas pressie got lost in the post - looks like you are going to deliver it

Looks fantastic mate.

refractions

No problems. Glad you got it working.

Just been looking at the new aeroquad config package, it would be great if you could implement the bit where they can upload the code to the quad using the same package - saves swapping between the two.

Hi, I haven't changed anything in my code other than enable specific sensors - never touched the #minthrottle value - my esc`s are rctimer. I followed the instructions from : http://www.multiwiicopter.com/pages/multiwiicopter-wiki You set your subtrim on your transmitter to give the values needed. I...

refractions

Do you see any movement from your transmitter in the gui? If so, what are the minimum values you are getting? You may need to adjust the endpoints on your transmitter to get the minimum value required - mine is set to:

Low 1095
Mid 1500
High 1905

Hi, Sorry to hear about the smoke and fire. Basically you just need to set your transmitter to aeroplane mode. I have flashed mine to the er9x software, and one of the great things about it is that it allows you to set the switches to whatever channel you want. There isn't any issue connection your ...

There is this available on line at the moment.

Really? Bugger - i was just going off what the guys who make the paris boards told me. Cheers for that, looks messy with cables hanging out.

Iain

refractions

Hi,

I have the paris V4 board. What you say about the esc connections is correct. You should be ok other than that. Basically your battery only needs to power your ESC`s - and one of those powers the board, and the RX.

Iain

Hi, Did you get any further with this? Just starting to play with the idea myself.

Hi,

Sorry for delay. Still looking into this - doing the same as yours at the moment, but bringing my logic probe home from work tomorrow, so hopefully will manage to get it sorted.

Hi,
