Kaip išsilaikyti radio mėgėjo egzaminą ir legaliai skraidyti su 1.2 GHz video siųstuvu

Apribojimai
Kadangi FPV skrydžiams reikalingas video siųstuvas RC mėgėjai renkasi iš esamų rinkoje analoginių video siųstuvų. Pasirinkimas nemažas, tačiau transliuojami dažniai paprastai būna šie: 900 MHz, 1.2-1.3GHz, 2.4 GHz ar 5.8 GHz. Kai kuriose šalyse galima naudoti tik tam tikrus diapazonus. Pavyzdžiui Europoje yra draudžiamas 900 MHz dažnis, nes jis naudojamas GSM sistemose. Lietuvoje 2 diapazonai patenka į dažnių nereikalaujančių specialaus leidimo, t.y. 2.4 ir 5.8 GHz. Tai vadinamasis ISM dažnis.

Tačiau nors leidimo šiem dažniams ir nereikia, yra ribojama galia kurią gali spinduliuoti siųstuvas. 2.4 GHz skaitmeninei moduliacijai leidžiamas 100mW spinduliuotė, kai tuo tarpu analoginiam video leidžiami tiktai 10mW. 5.8Ghz ruože atitinkamai 25 mW. Kas yra bandę tokius galingumus, pastebėjo, kad realus jų panaudojimas galimas tiktai 100-200 m ribose. Bendru atveju tolimiems skrydžiams tokios galios neužtenka. READ MORE

UAV/FPV shop has launched

Added event’s calendar

To whom it may concern: we’ve added calendar for upcomming events. If you can and want to join FPV flight – you are welcome.

Repair of the foam plane

After last flight I need to repair my plane. Front side is shaped out, side wall is cracked. What use for repair: epoxy adhesive, packing tape and plastic tubes, which are used to ship electronic parts samples. These tubes I’ve glued to on both sides and body became more or less straight.

Plastic tube is U shaped, so it is stables in all positions. Some weight is added so plane now fill fly not like an axe, but more like a brick. Hole for the mobile phone weakens the body, but I didn’t closed it, untill I figure out anothey way to capture video.

After repair front of the plane looks like new. Only expert could tell that there was an accident:

This time I’ve wing supports stronger. I’ve used that U shaped plastic tube and much more epoxy glue. Mountains of glue express the beauty of the interior design and makes body stronger. Packing tape gives mysterious look and make the plane unique.

White hawk down

Once I’ve decided to fly despite the heavy wind. Everything went ok, but doing a loop near the ground the altitude was too low (mayby a wind rush). It was not the first time the plane crashes, but this time it was damaged a little bit more. I’ve made a hole for a mobile phone, so wing support became much weaker. The result was cracked wing support and side wall.

Even so I have to admit that foam planes are difficult to kill, even after tens for crashes plane can fly without much repair.

Moral of the story – low altitude, wind and unskilled pilot can lead into crash.

Hello world!

I’ve become interested in RC planes. I’ve got some ideas and notes on this topic. Zebediejus pushed my toward creating this site. I’m also thankful for server machine. I’ll try to post some info about what did we encounter when we’ve started to fly RC plane. Mayby it will be interesting for someone, and I’ll have where to show photos and video.

I don’t suggest to use solutions which you will see on this site, they won’t be the best ones. The purpose of this page is not to be novice guide, but sort of “how it can be done” version. I’ll show you what equipment I do use, why I’ve chosen it and what’s wrong with it.

Why site name is FPV.lt ? FPV is an abbreviation from First Person View. It’s what the human would see being in operated object. That’s my purpose: to do such plane. There are plenty commercial producs, they are pretty much expensive and dull. I don’t want to invest much money in it, but also I don’t want to do everything from the scratch. Some say it’s impossible to do fast-cheap-good. It’s trye, we’ll to it cheap and good.

So much for a now. If you have any notes, commends about this page please use comments or just email me stgedas at gmail.com. We need feedback from you to become better.

Cheers
