Hello again! It was about a year since I visited this forum last time. I never got my F550 working properly last year, so I let it rest during the winter. I got it flying last summer without problem . After some fuzz I also got the video-link and the remote trigger for the camera to work. But I...

Now I see what you mean! The C-rating of the individual batteries does not change off course.

That is wrong. If each battery can output 240 A then two batteries can supply 480 A.

For a small craft I would say that fewer batteries are better because of less weight. But when it comes to this size I would say the opposite; The weight saving would be minimal with such large batteries. Amp throughput is probably more important.

If I understand it right, it works like this; If one blade have larger pitch it will also have larger drag and larger lift. The larger drag will give it larger lag which compensates for both the extra drag and lift.

As I said in #14...

Burned my thumb on the soldering iron when trying to hook up the power to my video tx. My F550 now have two bec voltage regulators. One to provide five volt to the hdmi-converter and one to provide twelve volt to the vtx. Most other gizmos requiring 12v run happily on 14.8v, but not the vtx. Got...

I had to go check my F550 just to make sure, and you are right. Motor numbers go counterclockwise, not clockwise. Anyhow, the way your MR spin in your video clearly show that the FC does nothing to stabilize it in yaw, on the contrary, it just keeps spinning faster. That makes me think that you...

Front left motor is number 1 Front right motor is number 2 Rightmost motor is number 3 ...and so on in clockwise direction Odd motors spinn clockwise and even motors spin counterclockwise. Set your F550 up like that and you will have no spin.

Is your motor 1 front left?

Now wait a bit! Aint the odd motors supposed to spinn clockwise and even motors counterclockwise? What motor/ESC have you plugged into port one?

My guess is that one motor is spinning the wrong way.

Quite impressive. Compare that one to the RALPH camera on New Horizons which was built ten years ago with a equivalevt of ISO 1,638,400.

F1 and F2 for gimbal control is for non DJI gimbals. The H3-3D get all the input it need via the CAN-bus. If I'm not all wrong, it is the NAZA-lite that is limited to hexas.

On another (photography) forum I attend to there is a discussion whether RTFs are overrepresented in the "stupid flights" genre (like flying near airports etc). Some say it's only because there are far more RTFs sold than ATFs. To verify if this is true I would need some help with sale...

Still the same hillarious lens distorsion as all previous GoPro cameras...

I think those propellers are too large for the motors. Check the spec for those motors. I would go for 920-980 kv motors for a frame of that size.

On my F550 I carry a 5500 mAh battey + gimbal + camera for a AUW of about 2,7 kg. A bit heavy, but it's not the 920 kv motors I worry about. If in doubt, use eCalc to get the performance envelope.

All 900-980 kv motors I've seen have been speced for 3S and 4S. All of them are not capable of swinging 10" props when running on 4S, but some are. If you are going to swing 15" props you definitly need lower kv motors. The motors don't care about how many mAh your battery has as long as they...

The E300 propulsion system runs just fine with 4S batteries. The other motors will probably be fine with 4S as well, but there is a chance you have to go down to 9" props (I didn't catch the brand and model)
