This is my new FPV250 build so far:

-Multistar elite 2300kv motors
-Afro 20A Slim ESC with BLHeli
-Multiwii 328p ( HK )
-5V SBEC
-OrangeRX receiver
-UBlox GPS receiver
-GPS <> IIC adapter
-Bluetooth
-MiniOSD
-Sony 600LTV FPV camera
-200mw mini VTX ( Banggood )
-2200ma 3S 25C lipo

Is the 25C battery enough or should I go for a higher rating ? It should be enough but I am not very sure about the quality and real rating of Zippy compact packs.

On the first flight, without any tuning ( default pids ) I noticed a constant yaw drift to the left ( when hovering ) what could cause this ? Can anyone share their pids if running the same board ( 328p ) ?

Also any other suggestions about the setup are welcome ! I intend to fly this for aerial video and will run a mobius with a front mount gimbal that is currently under construction. I wanted the smallest quad possible that I could carry without problems and still be able to produce decent quality video.

My experience is very limited with small size quads, till now I only run ArduCopter powered large octocopters.

Thanks !
A yaw drift is more likely a radio issue, are you sure your yaw is 100% neutral, and it is shown as 1500 on pc gui ?

Possibly you need to define a deadband in the multwii configuration

Also, I guess you have a on board mag, once you enable mag mode, assuming you did calibrate right the mag, you can't have any yaw drift


About 25c bat, it is even more then needed , I use a 10c on mine

Hope you enjoy watching:

Ponds are your friends lol
Those are two awesome videos. Strong work guys, very impressive.

I hope to be building my fpv 260 soon. Half the parts have arrived, still waiting for the 2nd half. Then I will undoubtedly find that I forgot to order the 3rd half of needed parts.

My FPV260 long-frame version, as clean build as possible... Still under construction and tuning. Currently using a CC3D, but a flip32 is already on the way. So heavy for such tiny quadcopter... Agile and swift, but definitely not precise just yet for obstacle courses. (The silver testicles are parts of the sonar module.)
Its sound is kinda annoying... Using (probably fake) Gemfan 5x3 3-leaf props from banggood, gotta try something else.
