I posted in the welcome section and was told it would be good to do a build thread here too, so here we go, 
I am open to any advice/ suggestions and ideas as this is my first build, I have phantoms and although my flying skills are not great I am a qualified engineer and have been reading/researching this for years but only now I’m taking the plunge…..I can solder and have a good understanding of the basics such as beta flight and I feel pretty confident in getting this build flying (hopefully)
Ideally I want a quadcopter that isn’t overly expensive or complicated, that I don’t mind rebuilding when I crash ? 

I have purchased
 a tarot 7” frame
Speedybee f405 stack
RadioMaster pocket elrs and receiver ( can fit the 1w when I’m ready)
Need to get motors batteries and a fpv system sorted, I do have a 5.8 screen with built in receiver from previous quads. 
Planning 2808 or 2806.5 motors or possibly 26xx if I can find them, a 6s Lipo ( possibly li ion in the future).may even put my own together too
I don’t plan on freestyle tricks or anything really really aggressive so maybe smaller motors would be beneficial over 28** (from what I have read builders using 22** motors have found the quadcopter underpowered ?‍♂️
There’s some very inspirational builds on here that anre a wealth of knowledge and I am currently working my through them all. 
Thank you

Hi Gyr,

What is the AMP rating on the F405 stack?

Later, iFly

It is 50A…..

It sounds like you're off to a great start with your first build. Given your background as a qualified engineer and your experience with Phantoms, you're well-equipped to tackle this project.

Regarding motors, since you're not planning on aggressive freestyle flying, you might indeed benefit from smaller motors. While 2808 or 2806.5 motors are great, considering your use case, you might want to find that something in the 26xx range could be more suitable as they offer a good balance of power and efficiency for a quad that's not focused on high-intensity maneuvers. However, as you've rightly pointed out, going small (like 22xx) might leave you feeling underpowered. So 26xx would be my best bet - just a thought

For the FPV system, since you allredy have a 5.8 screen with a built-in reciever, you might want to start with that and upgrade as you feel necessary. It's always good to utilize what you already have, especially on a first build where you're testing the waters.
When it comes to batteries, starting with a 6S Lipo is a good choice. Li-on could be an interesting experiment down the line, especially if you're comfortable with putting your own packs together.


I'd also recommend checking out some resources on my website www.rcdroneguys.com, where I delve into various aspects of drone building and customization. It might provide some additional insights or ideas for your project.

Lastly, the 50A rating on your F405 stack should be sufficient for your build, especially if you're not pushing the quadcopter to its limits with aggressive flying.

Best of luck with your build! / Jim

Cheers jim,
It seems 26## motors are not very available it seems so I think I will go for 2806.5 1300kv motors, the ones I’m looking at are rated max amps of 45amps, and the stack is 50 with a peak of 55amps… at 100% they give 2535g of thrust [that should be enough]. I’m on the higher end but should be good. It may cost me some flight time but I’m hoping it shouldn’t be too bad and the extra grunt / speed may offset this. (Could be wrong mind )
I will go for 6s LiPo but I don’t mind making my own lion packs further down the road to increase flight times. I don’t mind soldering and can tig weld/ spot weld to make packs.
Regarding the fpv system I will use the screen I have for the time being and might try goggles later on.    I need to choose a 19 mm mount camera,a VTX (probably rush tank or similar with smart audio)with a decent output and antenna to suit. 
A buzzer and some other things like heat shrink/ wire sleeve to keep wires on the arms and to make it look nice and neat
The building/assembly and soldering should be easy enough, it’s the setup and tuning that will be the biggest challenge. 
As soon as I get everything I need I will start the build and document it all here, it’s quite an exciting project and if this goes smoothly then I can see me doing a small indoor project too ??

Well I have put together the frame, motors, fc/ sec stack and receiver! The assembly was straight forward and didn’t encounter any problems, phew. Soldering went ok! It took me a while to get through the beta flight and transmitter settings to get all the switches setup and even managed to get them to play tracks so I know when they are on…….
So….
I decided to have a little play flying los while waiting on a fpv camera and tx…..
WOW I am blown away with the sensitivity and power/ speed of this thing! It’s an animal! 
I will sit down later and use the potentiometer to either alter the throttle curve so it’s less sensitive around hoverpoint or adjust the throttle limit. 
I cannot believe how long I have put off building my own drones….. the setup sounded so complicated but using beta flight through the Speedybee app made things much much easier! 
To be honest Oscar’s site helped me out a LOT, anyway here’s the current progress! 
To say I’m happy that I managed to get it flying is an understatement!

The soldering isn’t 100% but I’ve seen worse! Lol

Hi Gyr,

Doesn't matter what it looks like as long as it works.

GOOD Job     The craft looks really clean.   Sweet !

I will take more pictures when I ad the fpv system and get the osd running…. Still cannot believe I did it and it all works! 
Compared to what I’m used to flying this is like going from a fiesta to a Ferrari ?! Yikes! Haven’t got near full throttle yet…… it’s rapid

Hi Gyr,

Yes.  That is my impression of my 7" Rescue Quad build.
The craft covers distance at an amazing rate and with very 
little throttle. It just MOVES FAST.

My problem is not having any place to really fly it, however,
it was built more as a lifter than a flier. For that, I think that
it has plenty of power. 

Enjoy your new build.

I have fitted a Speedybee tx800 VTX and a set of antenna, a runcam and am currently using a screen I already had, my next purchase will be a set of goggles I think, the drone is flying really well and I will be attempting some long range flights this week if the weather permits.
I have everything working even the tramp controls so I’m really pleased with it! Even managed launch mode ??
I could have possibly bought a better radio tx as I’m on the limit of switches, the radio master pocket is a great bit of kit and Elrs is a game changer for me! ??

Nice build! Watch your fingers. That little Pocket TX you purchased is a heckuva radio for the price. I might buy one just as a backup.
If I can find some wide open areas, I'd love to build/buy a 7" cruiser like yours.

I really like the pocket, it’s compact and comfortable, I’ve also seen online that you can swap the internal Elrs for one from inside a boxer and get 1w 2.4 Elrs ??

Yes it is possible, the screw holes are compatible and there is space enough for small fan, just order the internal module and its accessories originally for boxer. I'm also going to do this upgrade, just don't have time yet...

Do u know what version of edge tx they install with the module to enable you to get the full 1w? Is it boxer version? 
I’m thinking about possibly using the module bay on the rear and wire it into there if it is easier, i don’t need it just yet but want it all ready. 
Will do more research.
