DJI F550 build

[davey_b]

Looking to build a F550 soon which I plan to use mostly for putting my gopro on and taking video. Going to get a gimbal etc. in a bit but just want to get the thing up in the air first and so was wondering if folks could look at this list of parts and see if I'm missing anything or where it could be done better/cheaper/lighter.

Link to the dropbox excel spreadsheet on dropbox is here: https://www.dropbox.com/s/68dycg0tkg32jwh/DJI F550.xlsx?dl=0


Thanks

Only thing I would go different is gimbal 3 axis, price is bigger but filming is better. And this is why

 

[davey_b]

Yeah that makes sense, fair bit more cash though

 

[Kratos]

heheh tell me about that I am thinking to take your configuration my is over 1000 euros

 

[davey_b]

To be honest a 2 axis gimbal you can get for £40 and a 3 axis one you can get for £80 - £90 so it's not that bad for the quality you get from it. Other option is to build your own gimbal

I don't have expirience to build my own. Maybe some time later, but good gimbal to me is must have.
But flight time is minimal on this configuration.

That's not great, flight time seems lower than I would have expected

How much better would the flight time be if you switched to a 4S battery?

 

[davey_b]

Sorry thought that was for a 4s. I've done it with a 4s before and it wasn't a huge amount better

 

[Kratos]

It is very difficult (al least for me) to have big flight time and to stay in low budget... I think main problem all multirotors is flight time. Do you have minimum flight time?

 

[davey_b]

Nah, not really, 10 minutes or more would be nice but as long as it's more than 7 minutes or so of hovering and gently going about that'll be fine.

 

[Kratos]

Try 700-800 KV motor, and experiment with different blades and pitch.

 

[eskil23]

Do you have minimum flight time?

The time it takes to haul the camera into position, take the shot, get back and land. Sometimes 30 seconds is enough.

It depends from person to person. For me 30 second is not enough. I need steady video clips 2-5 min.,so 20 min. in hover minimum but that cost. Anyway I dont want to replace batteries every minute plus I dont have money for multiple batteries At this moment I am thinking to invest my money in something else, but then I quit and that is not in my nature

 

[eskil23]

From task to task rather than person to person. 30 seconds flight time is not enough if what you need is a 5 minute reel. A flight for a still can be as short as 30 sec, but I would like to have some margin on top of that.

Five minutes is what I get out of my F550 with gimbal and NEX-5 (calculated, not tested to the limit yet). It is enough to lift of, fly a few hundred meters, fly around a while while trying to get a few good angles, get back and land.

 

[davey_b]

What motors, props and battery do you have on that?

 

[eskil23]

E300 and 4500 mAh

Can anyone help me please with this problem i am having on my F550

 

[davey_b]

I've heard that sort of thing can be caused by props on the wrong way. Check they are all in the correct position with regards to clockwise and counter clockwise

Look at my sig. 4s 5000. I get 10 minutes of easy flying and hovering. Id also recommend a 3d gimbal.
