Oh okay fine ! Because mine came upto 14000 for now ! I was wondering how did you get there stuff so cheap! And where did you get those male to male connectors ?

hello
         
                anyone using Emax cf2822 with 10*4.7 slow fly propellers for quads ?

I built my first quad with the 2822 motors. Along with the v2.1 control board flashed to v4.7. Used the cheap hk ss 18amp esc. Home made frame. And the starter 2.4g tx/rx from HK. Total weight was about 1.1kg including a 3s2200 lipo.

Used the 1045 and 1047 propellors. Was too much thrust. Replaced with 0845 propellors.

I also have a quad with CF2822 motors, HK 18amp ESCs and I am using 7x4 props.  Seems to work well. Bigger props may be too much for these motors.

Thank you Mr.Anwar  it was  so kind of you ! Hope  my quad files

I am facing a problem with my first quad which has similar setup. The motors are emax 2822 1200kv and one of them spools up late and stops intermittently especially when control sticks are moved. Couldnt lift of due to this and searching for a possible solution. The said motor seems to be bit more tight compared to the other motors. Since I couldn't find any other reason, I am just assuming that this may be is due to the HK standard QC and I might be the victim this time. Though the price of this motor is very cheap compared to its specs, waiting another month to finish my home made quad is....

Have you tried changing the position of the motor?

If you are using the HK atmega board, flashed to v4.7, there is a problem with the signal to the M4 motor. You can find details of it on various forums.

You may want to use the trim to get the motor to spool up along with the others. I also tried oiling the bearings on my 2822. Seemed to help, but did not have the equipment to measure the changes.

With my setup, I found it hard to get the quad to hover and land smoothly. Was easier to fly it and crash land it. But then, I am a beginner to RC and this was my first build.

Thanks subhashr, my setup is stock firmware right now and later will change to X config. I got a tip from Pikle6 just now about stick centering which I missed. Will have to try it out and see if it helps.

That is a lesson in dealing with these ultra cheap stuff. We have to plan for the eventuality that one of the items will go bad, so I ordered 5 sets of motors and ESCs from the get go.  An extra pair is so much helpful (along with extra props) when it comes to surprises like this, and you can always use them for other (non-quad) builds.

My HK board based quad including videos are here :

The CF2822 with 18A SS ESC does work fine in general.  I picked up this parts list because I saw Ashta bhai using them.  So there is definitely a history of this combination being successful, at an extremely low price point.

Anwar bhai, I did order 5 ESCs for the same reason, but unfortunately I gambled with the motor and got hit Anyway, lesson learnt  

And using a simple cdrom case with couple of screws was pretty ingenious !!!

I learnt this a hard way... I had bought just 4 ESCs and exactly 4 motors. After a crash, the crappy dt700 motor became very tight = more friction = burnt ESC.
So replaced the ESC but didn't buy the motor. I undid all the grub screws of the motor and fitted back again, but the motor was still tight.
So had to buy another motor. A total delay of ~ 1 month (thanks to HK and HKPost)
I now want to have a spare for every piece, and would NEVER want to buy dt700 or dt750 or any other bell-type motors for quads. I especially hate it's grub screw-type mount and weak build. NTM prop drive 28XX series appear to be better at a small extra cost...

Is it with or with out battery? And the aluminium version looks fantastic too!

 salim its with the electronics .. have some gyro setting left

correction sam*

Wow!  I am just a novice in quads but if its with the battery then its a very nice AUW I guess . Am also in the same weight range I think with my corrocopter. Awaiting video

Nice build Yogesh bro. Waiting for videos. Just one suggestion, mount the props near to motor bell.

dharmik bhai ,
                   
                    thats the maximum it can sit on the shaft ....  need some help with the gyro settings

Hi Yogesh,

Have you completed your Quadcopter. What is the current status? Just curious. Your thread gave me a good insight.
