Whats the flight time on that now?


On another note, I was thinking of ordering the DJI Vision 2. Anyone here got one yet?

I wouldn't get one for the following reasons.

It uses proprietary batteries that are stupidly expensive.
The camera is very average.
It uses non-standard frequencies for control and video/data.

I'm not DJI's biggest fan but if you want something that'll fly out of the box you can't beat the original Phantom, add FPV gear and a gimbal and it'll be an order of magnitude more flexible than the Phantom Vision. You may give up the 20+ minutes of flight time but with the money you save you can get a bucket load of batteries.

I was looking at one too, and the inability to upgrade the camera and the "you must use the supplied battery and buy more from us" kinda put me off. If i want to take it out into a field, i want it to be able to fly for more than a few minutes without having to land, then change batteries.

Doesnt look as sharp as the gopro either...
 
I was wondering about this the other day. If your plan is to add gimbals and FPV, etc why even go for a Phantom of any sort in the first place? I know its easier to get in the air for first timers, but you may as well build your own and learn how it all goes together. You also wont be limited by all the proprietary stuff later on.

The nice thing about the Phantom is that it's very portable. I have mine in a flight case and can just whip it out and get it up in the air in 2 minutes if I see something I want to shoot.
 
With an F450 or TBS Disco you need to be more careful about how you handle them. GPS mast, exposed wiring, landing legs etc. The Phantom is more hardy and can be dropped, knocked and chucked in a bag without worrying about anything breaking off or coming loose.

Although I have an F550 and an S800 (not quite built yet), the Phantom is still my go to multi for a quick fix.
 
I love my P2 (Non-Vision). 2 batteries and I'm chucking it around the sky for the best part of an hour! Very robust and an easy learning curve too, I'm gently getting into flying ATTI mode which is taking a fair bit of getting used to, but it's nice being able to just switch back to safe and easy GPS!
 
just taken my self build out today for the first time in the garden bit shaky but i think i did ok and landed in one peice, did go about 15m high but for the first time just kept to a hover with multiple takeoffs and landing. The only problem that i have is that its yawing a lot, tried a bit of trim and that didnt help, any idea's ??

What flight controller are you using? :)


Sounds good though, any maiden that doesn't end with a bag full of bits is a good maiden!

I am using the KK2.1 board with SW Version 1.10S1

Ive been doing small test flights in the daughters bedroom as too scared to take it outside but anyway i did it and enjoyed it. I was ******* myself when i took it so high (well to me it was high)

Cool, I have a KK2.0 so I guess the interface is similar. If you've calibrated the ESCs and let the sensors calibrate you should only need to trim it a few beeps/clicks.

Couple questions, in the receiver test screen on the KK is it showing the sticks as centred at 0?
With the yaw trim at 0 on your Tx how much stick input do you need to stop it turning?

Was meant to say in my last post, I evidently forgot!
If you ignore the transmitter/receiver you can get the whole lot for anywhere between £100 and £150. Budget transmitters can be had for as little as £30 but I have no idea how good/bad they actually are!

You could put together a starter quad with good components and a KK2.1 for about £175 including a couple batteries.
Then if you don't have one already you'll need a transmitter and reciever, about £70 for a good cheap one (Turnigy 9X + FrSky module and Rx, my bro has this combo and it's fantastic).
So say about £250 for a complete starter setup.

If you want GPS assisted modes you'll have to spend about £150 on top of all that for a flight controller with that capability.

Thanks, I think I'll maybe get a bit of experience with some ground based rc projects first and then try a quadrotor since I should be able to reuse some of the bits.

yes sticks are centered, the yaw happens when in the air it rotates anti clockwise and have to keep correcting it with the rudder

Any yaw is going to be because one pair of motors is creating more torque than the other pair.
If the KK is showing the sticks are centred and 0 then it isn't anything to do with your Tx, Rx or signals from them. As it's a new KK board it probably isn't any settings on the board (I can't even remember there being any trim settings on the board itself).

So that pretty much leaves your ESCs or motors.

How did you calibrate your ESCs, one by one or all at once? through the KK2.1 or directly attached to your Rx? did they all give the calibration beeps?
Do any of the motors feel stiffer, gritty or otherwise different to the others?

I assume you've done all the usual sensor test and sensor calibration.

Has anyone had any problems with one of there quadcopters.
wanting one to film and take photos.
read about them just flying away on there own, can anyone recommend these quads.
thanks in response
 
Unsure if to get a F550 or Phantom 2!

Not had a copter before, will be my first. I don't really have a massive interest in building one but will with the help of friends if its worth doing so with the F550.

Any help appreciated, however I do like the look of the Phantom 2!

There isn't really many components if any that can be carried over unless one or the other is compromised. Different style transmitters, higher ampage speed controllers on a car usually,different mmotors, no flight controller on a car. It's mainly the experience in building it plus the batteries that will carry over. From what I've seen a self build car costs more than a entry level self build quad if you want something worth having.

I calibrated the ESC to the kk board by pressing all 4 buttons on the kk2.1 board and power on. Also programed the esc all togethrer by pressing buttons 1 and 4 for kk bypass and programmed the esc.

When powered on the esc beep in the following order 1 3 2 4 with a slight twich on each motor .

i did do a calibration when first set up and then another outside before i took it outside for its first flight
 
Just ordered a Phantom 2 Vision. Been looking at one for a while and altho people suggested getting a normal version and adding a camera and lipo batteries I havent the patience to do this, just want to buy and fly.

All being well Ill get it tomorrow and flying over the weekend, weather permitting.

Anyone got any tips for this machine?? Ive read that there's a switch somewhere which changes the distance from 300 meters to 500 meters. Not sure if its an american thing or not (different frequencies etc), but an extra 200 meters should be good :)
