Making an FPV drone

[Snibelsnaps]

Desided yesterday to build a drone.
Then i designed a frame that i will print out of nylon/carbon fiber filament.
Measures 240-300mm(dependant on arm length, i have several designs) across motors, components can be placed in the rear or the front.
Frame weight is 94g+ fasteners.

Can someone help me choose the parts i need to make it fly.

Budjet is 500€ for all the stuff i need for it including a controller and battery charger.

I live in europe so i rather not order from china due to taxes and insanely long delivery times.

You need:
1. Motors. Emax eco 2400 kv
2. Flight control board. Omnibus f4
3. Escs. Racerstar 30 amp single escs.
4. Power distribution board. Matex pdb xt60
5. Transmitter. Jumper t16 or radio master t18
6. Reciever. Frsky xm+
7. Propellers. Ethix s4 props
8. Battery. RDQ 1300 mah 4s

That is just to get you in the air. If you want to fly fpv you'll need:

1. FPV camera. Caddx turbo with mount
2.VTX. AKK fx2
3. FPV goggles. Eachine ev800

This would be considered a basic budget build it gets a lot more expensive.

All this might go slightly higher than $500 so you could go cheaper on some components like the transmitter and reciever you could go flysky and shave $100 right there but it's all up to you.

Good luck!

Thanks Dugdog47!

Are the goggles a must have, since i have a plethora of old and new monitors 5-20'' i can use as an image feed?

Allso the image receivers do they have standard connections so i could basicly make goggles from 2 old camcorder eye pieces?

havent tested the latency on two phones using whatsap video call that might be a solution.

Initially can just learn to fly line of sight and kind of a good skill to have if you need to do it, that said different skill from flying fpv. For fpv you'll need a vtx on the quad that sends the analog video over the air as RF and then a receiver that picks up the 5.8GHz signal you can find video receivers that output HDMI or RCA so can adapt that to vga if you wanted but really some cheaper goggles like dugdog linked are a good start too. I've got some Fatshark HDOs now but still have my eachine cheap ones for handing off to people if wanting to stay in budget but get fancier looking goggles can checkout skyzone or aomway brands they are both cheaper alternative to Fatshark. I just got DJI digital goggles too but waiting on the airunit if none of my friends want my HDOs I'll put them up for grabs here too.

Also you are best off getting the transmitter/controller (jumper or radiomaster) first since can use sims on your computer with the controller as input to learn to fly acro mode there without rebuilding a thousand times (believe me I printed my first frame too and printed like 20 replacement arms over time )

Would this work?

I think everything listed would work but couple things I would tweak.

For transmitter have hear bad things about lock in with ACCST protocol I like any radio that runs openTX software (largely worked on by frsky but also an open source project), however I also like the ones with a module bay for the transmitter radio since they usually come with 4in1 transceiver module that can bind with frsky or DSM receivers among a slew of others and can eventually upgrade to TBS radio for long range if you ever get into that (more than 500m or so away).

For the props those might be nice being CF but will probably break quickly and are pretty expensive relatively speaking get some 5x3 (5 inch 3-blade) dalprop with 3.0-4.5 pitch will be labelled as 5045 or 5030 3 blade props. Can fly with two blade but less stable since less authority, but get more flight time with less blades typically since less mass for the motor to accelerate and just more efficient overall. Also plastic props can be bent back CF will crack I imagine if it hits anything hard.

Don't buy that taranis radio. For about the same money you can get the radiomaster t16 or t18 that can do everything the taranis does plus about 100 other things.
