FPV Knuckles H-Quad Build Log

[jhitesma]

If you were closer to me I'd offer to buy that burned one for a few bucks. I've got one that was crash damaged and I suspect between the two of them one working one might be hobbled together. But not worth the cost to ship broken electronics overseas just to try and salvage components

 

[Tomtom]

Indeed, I don't think this worth the cost of shipping + custom. That's too bad, I like the idea of electronic scavenging

Hang onto it then, chances are eventually you'll have another broken one or two :black_eyed:

Customs? I don't think you have to pay customs for a gift - for a broken gift that is anyway =)

Don't jinx it jhitesma! I will hold you responsible if something happen to the next one

Probably not indeed. I'm just so used to have to pay custom from parcels between the US and UK that I always include the cost of it. You know, just in case.

Nice paint job. You have a beautiful machine. Can't wait to see it fly.

Thanks! I should receive my new FPV Tx soon. Hopefully, I will be able to fly this week-end!

It's alive!

What a pleasant surprise today when I came back home, my new FPV Tx was arrived!

I finished my video cable, plugged everything together (triple checking all connections to be sure not to fry the Tx) and it worked! Here are few pictures of the finished product:











I now have a AUW of 724gr with a 2200 mAh LiPo + FPV gear. Without the FPV gear, it goes down to 690gr. I'm quite happy about that because I added stuff and managed to decrease the overall weight. It's not as much as I expected / wanted but still a good improvement (was 785gr)



And here are a picture with the FPV gear the receiver part on. You can see the image on the screen



Next step is to build my FPV goggles out of foam. With luck, I will be able to fly this weekend!

Looks great! I love my H-Quad as well.

Thanks!

And I finally finished my "ground station" (if I can call it this way as it looks awful ).









As you may notice, I started the build to be a DIY FPV goggles. Turns out that my original plans were way off and need to be redrawn. As I didn't want to look funny for the other people with a huge foam helmet on my head (I didn't want to wait either, it's been more than 4 weeks now that I'm on that build) I decided to turn my first attempt into a integrated FPV screen with sun blocker

My first FPV fly will be this afternoon. Hope everything will be fine.

Stay tuned.

Good luck on the flight. Get some good video.

Maiden FPV flight check! That was really really cool!

But much more complicated than I expected. I mean you really need to be reactive because I you don't, you can crash easily. Anyway, 3 LiPos down and no crash today, awesome! Although, I didn't go very far as it is my first FPV flight (obviously) because I don't really trust my FPV gear, at least for now and more importantly, I don't trust myself enough

I didn't do a proper range test as I didn't have a friend today to help. However, I did rich a maximum distance of 150-200 meters successfully. I also experienced lost of signal a lot of time when even if I was close to my ground station (around 30-40 meters). Is it possible that the orientation of my vTx clover leaf antenna (facing down) could cause that? From my understanding, the radiation should be like a sphere so I should not matter. Well, to be fair, my cheap Chinese screen goes dark (or blue) when I loose the signal, I don't get static. Maybe there is a delay when the signal comes back to get the image back?

Anyway, I'm pretty exited to fly FPV again. I'll probably train myself tomorrow

EDIT: I forgot to mention but my camera mount with dampener balls seems to work well, I didn't have jello on my video

The radiation from a cloverleaf is more like a doughnut. This thread should give you a good explanation http://fpvlab.com/forums/showthread.php?16395-THE-ULTIMATE-5.8GHz-VIDEO-LINK-(AND-SIMPLER-OPTIONS)-EXPLAINED

Thanks for the link, very useful. I'll try to perform a proper range test next time.
