Best RX satellite location ..

In the bin.

Re: Best RX satellite location ..

Dont need no stupid Sats

Getting a nice fleet together Tom

Rob, are you seriously saying you run a 500 with no sats? That's brave isn't it?

He's on Futaba Tom

You just need an R6203SB.... it will not cause log entrys it will not show faded signals it wont keep switching because there are lost packets...

Yes you can run any helicopter without sats.... Just take the plunge and reception problems will be a thing of the past (and programming issues a thing of the present)

Its one of thiose things that if you buy fright in the first place you wont have to do it again... (Wots a sat ??? )

OK - I'm showing my ignorance here then, but the placement of the spektrum satellites is for specific reasons - receiver diversity and polarisation diversity. How do Futaba get around these issues without discrete antennas/satellites ?

Beat me to it mate!

Hahaha...that made me laugh

They dont....

Its just like zaphod beeblebrox's automatic dark glasses (they go completely black at any sign of danger so you cant see it).

Futaba users dont see log issues on their vbar, so it keeps them happy.

diversity is 2 aerials. polarity is aerials on 2 axes. Futaba has 2 aerials and ideally placed at 90degs to each other thus giving both diversity and polarity on a single aerial pair.
But then again futaba never intended the pilot to fly very very carefully and dead flat and straight so that each aerial pair could stay exactly parallel to a horizontal or vertical polarity while running alongside the modelt o keep signal strength up and simultaneously counting the number of other spectrum sets that may already be switched on and you might infringe by getting close
Bottom line: it works

Bottom line... you forgot about the 3rd axis, and about shielding.

Personally I like the possibilities of more than one sat, and having line of sight from my Tx to one of those sats in any orientation, but each to their own.

I really dont want to turn this into a futaba vs spektrum rage thread, but, is futaba really THAT more reliable than spektrum, weve all seen the problems spektrum have had, if thats down to the system or not i dunno.

Has anyone EVER had a problem on futaba?

Mr Mel swopped to futaba and dissed spektrum afaik, that has to say something..? thoughts.

avoidng the ftaba/spectrum argument as such: if you really think about 3D then even with 2 sats (or three or four) there will be times when some or all are pretty shielded by carbon or alloy unless you stick the things out on long stalks. The futaba suggestion is to keep those aerilas clear - of course.. and of course you can't from every orientation option either. What you can do is think about these things with whatever system. On my smaller helis i have one aerial donw one skid and one along the boom support: 2 axes, 90 degs apart and pretty exposed for pickup UNLESS the head:canopy direction is facing me. On bigger helis i geerally have one aerial forwards along the side of the radiotray and one aerial down on the vertical axis from that radio tray. Again good access all orietations UNLESS I'm behind the heli. Naturally i range check from the blind spot and on my spectra.. (has the biggest lump of engine and thickest carbon frames) I can range check 70 paces from the back of the thing at ground level.

To do any better with a 2+ sat system that uses each satellite as a single polarity diversity you'ld need to stick another 2 sats on the back end of a large heli (like me putting a second futaba there) because wherever you put yur 2 sats there is still blind spots just as big as mine.

If mmeory sevres for giant planks futaba actually do longer aerials... i's only the end coupl of inches that is aerial..the rest is coax.. so one could in theory widen and place the futaba aerials way more apart to cover those theoretical blind spots wheras the other system needs more sats.

Since range check power levels may not be the same a simple pacing test can't be compared (but jumping back into speckkie/futaba fight mode.. spectrum fliers can't count to 70 anyway). What you'ld need to do is take both systems full power and test them through a few houses and powerlined streets.. all that takes is a friend with the other system and a couple of phones
