5.8 ghz FPV EasyStar II setup


Here is my current Multiplex EasyStar II FPV setup. Max flight so far was 2.38 miles at 856 feet. The video was getting fuzzy at 2.38 miles, and I had several momentary control signal dropouts on the way home, but at 800 feet there was plenty of time to regain the signal.

your drop outs may have been caused by the fact that the sat rx was so close to the vtx. if you move the sat rx out to one wing tip then you should get much better control range.

ground station: if you kepp you control transmitter away from the vrx then you should also get better video range.

Thanks planemad man! Good idea, I hadn't thought of it. I have been reluctant to place electronics on the wings because I take it apart and transport in the original box. I might try moving the satellite to the fwd part of the fuse though. I think I also have a video problem because the motor pod shadows the vtx on the return trip. Turning 20 degrees and tacking like a sailboat helps, but it might be nice to mount the vtx on the tail fin to get the antenna higher.

Meanwhile I'm building a second ESII, just ordered EZ-UHF and 1.3 ghz video equipment.

also with the reciver antena and satalites you want all the antenna pointing in diffrent direction as much as you can.

The rx and satellite antennas are 90 degrees to each other at present. The satellite antennas are wrapped around the fuse so that there is a vertical component too. Maybe better if not wrapped?

i think if the anntennna are curved in use it ruinins the polarization but that is just me thinking out loud

Curved antenna? Question is moot because I flew into the radio shadow of a hill and did a nose plant from 300 feet. I'm gearing up to build a new ESII with 1.3ghz video and 433mgz control. I needed a good excuse to upgrade anyway. I do miss the crunched one though.

Hi Mutski,I have just stumbled across this thread in an attempt to find out some info on the HK g-osd 3 that I can't get to work.
Please can you show me the way to wire it up to the Immersion 600mw vtx and a sony 450 line camera.
The instructions are confusing to a newbies first venture into OSD use.
Please excuse me if I'm in the wrong place to ask, it's just I see you use the same equipment!
P.s I've just done the same as you, flew my Easyfly st330 into a dead zone 2km along a beach but the failsafe must have worked since it landed fairly softly into the rocks!
