"dear all
just start with APM 2.5 .......
all values about GPS and compass are ok.....
but values about vertical speed, altimeter, etc........ crap! the numbers are rolling..... and no variation of bank if I move the mock-up....
any idea what and…"
"very good, Joe...
now, it's more clear and I totally agree...... and maybe we had QSO B4 too...eheheh
I try to use the same skills in every field of telecomm's, sharing experiences, just to get the best obtainable, even with poor means... raising…"
"very good, Geoffrey
I will do, as I will finish my X8. now it's only a flying machine.....I have already all components, but the FreeTime.......
anyway, the plan is: RC radio RangeLink 433MHz, videolink 5.8GHz, XBee for APM2.5 900MHz, another RC…"

@Geoffrey
Hi, Joe from Namibia...I use the following antenna on our Survey UAV ( SurVoyeur -) have a look at my posting on DIYDrones)
1) Simple 1/2wave vertical commercial dipole ( it is simply a coaxial sleeve dipole -…"
"@ geoffrey
tnx Geoffrey for replying, but I disagree.
180 degrees is the same polarization.... we are talking about vectors 2 dipoles at 90° must to be feed with 90°delay (phisical, electric or a summa of both).... in the 3 elements of wheel I…"
"hi guys
the best "match" is using a vertical bent-dipole (on board) and an helix axial-mode (on ground)
for short distance, a circular-pol patch or a quadrihelix is allowable @ ground station
Big Wheel is essentially a horizontal pol,…"
