spektrum receiver

[kenninny]

When buying spectrum receivers some are full range, & some are sport, whats the diffrents? if any

[hghost]

Only receiver I saw that stated it was "Full Range " was a Spectrum receiver that had Telemetry capabilities.

All others were Sport Receivers and even some that had certain criteria Like AS3X or Flybarless for Heli's for example

But i suspect the term "Full Range " is because it covers a vast more than just a normal receiver....as Sport is probably just the normal receiver something along those lines

Just my opinion.

Spektrum isn't very useful for that are they?
Here's the RX currently available: www.spektrumrc.com/Air/Receivers.aspx

The electrics are pretty much the same for 'regular size' RX. It has more to do with shadowing of the Rx antenna behind battery and motor than actual range.
(BTW-unless you are using the very small 'toy' TX it is the RX that pretty much defines the range limit, not the TX)

The other major issue is the lack of antenna diversity and resulting shadowing in aircraft with large motors and batteries. Single short antenna (like the Orange RX and some older Spektrum) do not have the diversity of double antenna. The ones with remotes have even more diversity. A full range, with remote Rx is a better choice for any plane flown at a considerable distance.

Here's some tips from Spektrum: Installation Best Practices

Note: I still use 72MHz and have no trouble with it at all. The more people move to 2.4GHz, the less problems I have. My top of the line (used) RX are in the $10-20 range.

I personally use a DX6i for all my flying, and can honestly say the only RX that has ever let me down was an AR6115...at a range of roughly 30 metres! No brown out, no shadowing...it just died. The orange RX range has never once let me down, and the RX620 has dual antenna, and a satellite port. Considering it's a 1/3rd of the cost of an official spektrum RX, I penny pinch, and fly happy! my radian ( 2M glider) flies with an RX615 ( Single antenna and satellite) to the point of near invisibility ( approx. 2000 ft up), with no issues. I now have an altimeter, so the next time it's calm, i'll try and record the exact distance.
