Kobac, ti imaš još veću platformu tj. najmanje dvije veće platforme za FPV. Vrijeme je da ih malo načičkaš antenama.   
 
Evo set up da uštedim ljudima malo vremena.
 
 Hello everybody:

When I flew with the standard 35 Mhz. Graupner MC-24 my record was 17 km. range using a 4 meter rx antenna.

Since I started using the UHF T Scherrer LRS I have been improving my RC range considerably.

You can download my personal best range of 31 km. flight from this link:

It is a KMZ file. you can open it in Google Earth and see all the track and profile.

This flight was made with a 3 m. spanw. glider, it is the Grafas from Top Model CZ.
It took me 4 hours to complete the flight. I only used the electric motor for 24 seconds. I was soaring all the time in thermals and finally I found a hard mountain wave that lifted me to 3700 m. AGL. That gave me the posibility to go further to 31 km. range.

I am really satisfied about the THOMAS SCHERRER LRS.

This is my setup:

Model: Grafas Top Model CZ, 3 m. span. (14:1 glide ratio @ 50 km/h.)
Motor: AXI 2820/14
Prop: Aeronaut foldable 13x6,5
ESC: Jeti 44 adv.
Battery: Graupner LIPO 3S 5200 mah.
Aux. battery: Flightpower LIPO 3s 2500 mah.
FPV camera: Pixim DX 201
OSD: Range Video Gen 4 (with autopilot)
RC TX: Thomas Scherrer LRS (Standard whip antenna tx 0.5 W.)
RC RX: Thomas Scherrer LRS 12 ch. V 4 (two dipole antenna).Transmiter: Graupner MC24
Video TX: BEV 1.3 Ghz. 1.5 W. (3 db. whip).
Video RX: BEV 1.3 Ghz. (14 db patch antenna).
Logger: SM Modellbau GPS Logger.

sick!
super realizacija, vidi se da je sve optimizirao.

Tehnologiju se može nagurati u letjelicu, tako nadaren pilot se rađa, a s puno vježbe i truda se postižu takvi rezultati.

Tehnologiji je ovdje kumovao Thomas Scherrer, jedini pravi guru za RC - elektroniku na netu (R.Van Sommern takodje, ali uglavnom za motore)  i svatko tko se lati slićnih aktivnosti trebao bi proučiti:
http://webx.dk/rc/rc.htm - ovdje se može 'kopati' i proučavati danima... 

UHF sistem koji je ovdje korišten, mislim da je ovaj: http://webx.dk/rc/uhf-link3/uhf-link3.htm

Kada sam prije par godina otkrio ovu stranicu:  http://webx.dk/rc/RX-measurements/komplet-listen.htm  napravio sam onaj test na 26 km sa Zac1970 ... srećom, nisam se navukao na FPV.

Ovaj fantastičan uspjeh, kako  tehnološki tako i jedriličarski pokazuje da je besmisleno stalno napikavati i isprobavati ako ne znaš točno što radiš.
