Hello all,

New member here, I am in the process of assembling a 2014 3dr quadcopter, and if I use the included PM, PDB and the four individual ESC, wow what wiring nightmare to an already messy wiring of the existing modules and the pixhawk. So I thought I would use a 4 in 1 ESC. I contacted 3dr trying to purchase the one as used in the IRIS, with no luck. Is there an existing aftermarket 4 in 1 20A. ESC with BEC that is compatable with the Pixhawk? anyone tried any of the following ESC's with success?

1. EMAX 4 in 1 25A w/ubec ESC

2. HOBBYWING Skywalker Quattro 20A x 4 4-in-1 Speed Control for Quadcopters

3. HOBBYKING Q Brain 4 x 20A Brushless Quadcopter ESC 2-4S 3A SBEC

4. WITESPY '4 in 1' - B-20A Ice Blue series OPTO SimonK-(RapidESC)

Regards,

MAC

One thing I did was order 4mm female plugs as the Quattro came with 3.5mm female plugs and the leads were too long for my use.  So I cut them all to equal lengths and soldered 4mm ends to them.  My motors are too high a KV rating (880kv) and I'm going to shift them to 690Kv motors with 11 or 12 inch props.  For now they will fly stabilized but draws too much power which cooked one of my 8,000 mAh batteries.  Recommend you use eCalc to match the motors to the props and ESC you plan to use to ensure they are the best combination for your use.

Qbrain - motor DT700 - Apm 2.6 - Custom H frame Alu frame + GF booms + 3d printing - 4500mAh 3S

Second flight with wind 15 knots last 17.5 minutes with 4200 mA

Does anyone know the weight of the 3DR Quad frame kit?

Good afternoon everybody

I am very interested in the subject treated here.

Two questions : 1) which one is suitable for 2600 kv motors (i have had problems using a none SimonK esc with this kind of motor). 2) most of them appears to have a bec giving 5V and 3 amp such as do this one : APM 2.6 2.5 2.52 Power Module With 5.3V DC BEC. You can find it here : http://www.banggood.com/APM-2_6-2_5-2_52-Power-Module-With-5_3V-DC-.... So, please can i use this bec instead of the banggood one, that you can sometime find in a combo.

Thanks for reading, and answering to.

best regard.

this subject is a little bit "old"

may be i will have to create a new one if nobody answers.

are these small 22xx style motors? banggood has some racerstar 4 in 1 escs at 20 and 30a that some in the fpv racing crowd are using

@ ZaPf

Chronologically i received  4x1806 2600 Kv one week before the ESC, which were 4 ESC Afro 12 amp from HK EU.

I decided to check my motors using old ESC Plush 18 amp. Each attempt to make run my motors end as a failure.

Using another old ESC 18 amp simonk, i succeed to make run each motor separately.

That's why i ask all these earliers questions.

purposes using a 4 in 1 ESC instead of one on each arm are 1) less weight. 2) less clutter on each arm overall for a 250.

I apologize for my bad english.

Many thanks once more

Here's their 20a version:

I use HobbyWing 25A Quattro on two quadcopters, then flashed with BLHeli. They work excellent, no problems, hundreds of flights.

They also have a new product:

DG,

good evening (23.15 PM in France).

Thanks for your interest.

I prefer the BG one, because he has no BEC. So i will need, I will take advantage to, using the BG current sensor. With the advantage of wire and plug already ready for the Pixhawk.

Thanks for reading and overall answering

bests regards

@DG the bigger new hobbywing 4in1 also supports apm voltage/current monitoring and looks fantastic, but can't find it for sale anywhere:

Fnoop,

good evening to

Looks very pleasant.

I suppose that the appropriate wiring/plugs between this device and the APM or the pixhawk is included in the package.

bests regards
