Hello together

I try to build my first FPV quad with this parts:

• Emax MT2204 2300KV or  (only 3S)
  
• EMAX RS2205 2300KV or
  
• Eachine 2204 MN2204 2300KV or
  
• Racerstar Racing Edition 1806 BR1806 2280KV
  

• BetaflightF3 Flight Controller
  

• X-Racer Quadrant 25A 4~6S BLHeli_S ESC or
  
• X-Racer Quadrant 2-6S 25A 32Bit BLHeli_32 ESC or
  
• X-Racer Quadrant 2-6S 35A 32Bit BLHeli_32 ESC or
  
• FVT LittleBee 20A OPTO PRO ESC Little bee BLHeli
  

• Realacc X210 V+ 214mm 6K Carbon Fiber FPV Racing Frame
  

• DALPROP 5045 T5045 V2 3 Blade PC Propeller
  

• RunCam Eagle 2 800TVL CMOS 2.1mm/2.5mm 16:9
  

• Foxeer TM25 5.8G 40CH Transmitter TX TM25 adjustable Transmitter with Foxeer 5.8g antenna
  

• S603 Receiver RX 6CH 2.4GHZ
  
• Lemon Rx DSMX Compatible Diversity Satellite
  

• 14.8V 1500mAh 4S 40C Lipo
  
• 14.8V 1500mAh 4S 110C Lipo
  

Did I forgot something? Will this work together? Which motor/esc combination should I buy? Any advice?

I have a Spektrum DX6 and Skyzone SKY02S V+ 3D FPV Goggle, flight experience with Hubsan x4, Blade 350qx and of course many hours with Liftoff FPV Sim.

Maybe someone has a recommendation for better antennas for my goggles? It works fine for car fpv, but I am afraid, the original one from Skyzone won't work well with quad fpv.

I am grateful for every tip and help. And sorry for my english, it is not my native language.

I've just finished a build with that frame also, and looking at that receiver you are going to struggle to fit that in the frame as it is too long and thick (Oooh err missus lol)
Find the smaller receiver you can use.
You'll want 2204 or 2205 motors and check your FC is ok with Heli_32 I guess.

I would up the C Rating of the lipo to 75C minimum. I'm a big fan of the Tattu R-Line series (95C)

Thanks for the answer. I think I will take the EMAX RS2205 2300KV and the 35A ESC, should be fine together with the FC. Is there any other 35A ESC, that will work with BetaflightF3 Flight Controller?

As RENOV8R says, the 40C Lipos should change to something more powerful, it may works with less powerful motors, but with this combo I need something up to 120A, omg. 

Hmm, another receiver? This one or this? There is a much cheaper counterfeit, may this work together with the FC? I have no experience with Spektrum air receivers, I am coming from RC cars/Futaba. Found another one, much smaller.

Regarding rx, i went with lemon diversity sats with long antennas, 10$ and free shipping. Worked well so far on my last 3 quads.

Agree - those are the best I've found for Spektrum!  I use the regular (shorter antenna) lemons for my smaller builds.  Never had a bit of trouble with lemon-rx satellites.

I found this one, is it the right one? Do you have a link, where I can find it for 10$ with free shipping? Nothing listen at banggood or aliexpress, and ebay is much more expensive, nearly original Spektrum.

That's the correct one.  I haven't seen it for less than $13-14 though.

So I updated my part list with links to the products. Any improvements, changes or should I order so?

Your replies were very helpful, thank you very much. I have holidays in three weeks and am looking forward to assembling my first FPV quad, will certainly be an exciting experience.

Are you experienced in soldering?
If not, get a decent wattage iron, I used this one and had no problems (I was new to fine soldering too) https://www.amazon.co.uk/gp/product/B01F...UTF8&psc=1

Use lead solder with flux. Be careful though as I did buy one reel of lead solder that was actually lead free and was a horrible mess.
Copper shavings for cleaning the tip, much better than a wet sponge.
And practice on an old/broken piece of electronics. I used an old broken receiver and practiced removing and reattaching bits of it.
Also, I watched a fair few vids on Youtube about soldering flight controllers from the usual suspects Rotor Riot, Joshua Badwell etc.
Those videos were invaluable in knowing what to expect and things you need to do, there is soo much that needs to be done properly in these quads.

Oh, and a tip for the frame, I used longer stainless steel hex screws for the frame that I already had from my RC days. This reduces the risk of the stock screws stripping out of the standoffs and strengthens the structure a bit. I think there are normal M3 size.

Yes that's the one, and the place that i bought from. Maybe they were a bit cheaper when they were new... and i'm sure i had free shipping there but i bought 4 at once... Maybe it changed?

Thanks for asking, but yes, I am experienced in soldering for many years, profession and hobby. I use this solder, Stannol HS 10 Sn60Pb39Cu1.

And thanks for the tip with longer screws.

In the meantime, I received most of my stuff. Before I build everything, I like to test the parts, if everything is working as expected.

I know that the Lemon RX needs 3.3V, but I don't know where exactly solder the signal wire. I think it should be at the DSM2/SBUS Pin? Or is it the PPM?

Use the DSM/SBus row (bottom row) and then you'll have to bridge the solder pads next door to use "3V" (it's actually 3.3).

Thank you, maybe it was a dumb question, but it is solved now.

Successfully flashed Betaflight 3.2 on it, so it should be ready for the X-Racer Quadrant, thx to Joshua Bardwell
