Hmmmm have I posted a question that evades all SCC knowledge....Might have to head over RCGroups shortly....  |

:-) iv not used mine...n had my dx6i for about 6month iv only just worked out how to use the expo n switches lol But just cuz im slow dont mean i dont no how to use the range test.....i'll look in manual :-D thats if i decide go ever use it!! Cheers Paul but I've checked the manual P 50-51, it dosent shed any light as to why you would check with a reduced output signal. John Without the reduced ouput the only way you could properly range test 2.4 would be full range. You'd need a buddy, a car and a couple cell phones. "Keep going....Keep going....." Under straight line good conditions 2.4 can stay connected over a mile. 72MHz is range tested with the TX antenna collapsed to compromise the signal. Can't do that with 2.4. |

OK so you couldnt get as far as full range would allow, but dumb as it may seem I still dont understand why you would reduce the power to range test, is it simply to save battery power....But then even if it did work fine at 30 paces, its no good if it dosent work at 100 surely? Still confused, but thanks for the input anyway, John |

You are reducing TX output power (not saving battery). This mimics extreme distance from the RX. I have no idea how they come up with the metrics for it, just that (hopefully) someone with the proper knowledge has done that homework appropriately so you can check you TX > RX signal without having to get a half mile away.

Is it like fly said if we didnt have reduced signal power we would have to walk/drive a mile!
So with reduced its saving u walking so far to test!!??

Yes that could be a reason, and would be a satisfactory understandable answer if it is indeed fact. I guess I will never truly know. Reffering back to Dills idea of setting the turnigy RX switch to cause the lights to flash when I am out of range, I have decided just for the heck of it I will leave my tx at home outside and drive with the rx and lights until all the lights flash on/off. That should be a good range test. These HK clones I believe are not full range so shouldnt be too far. Thanks all, John |

actually, that's a pretty cool idea. I'll just need to go for a little drive with my fuselage and leave the transmitter at home. I think that unless you can keep a pretty good line of site to the remote though, the range at ground level would be a lot less than it would be when the plane is in the air with nothing in between you and it.

Yes Dill its amazing what we can come up with when we put our great minds together! ;D
I get what you're saying bout line of sight though.
I was gonna leave my lights switched off so when they start flashing I know im out of range.

Don't think you sould have a problem with range,
Iv flown my super cub,wing n edf up to a dot with no range problems!
And never range check!!

The range test feature reduces transmitter output by a certain amount (not sure of the exact number, it doesn't matter). The theory is that if your aircraft will respond at 30 meters at the reduced transmitter output, then it will respond at full range with full transmitter output.
I almost always do a range test before the first flight of the day.
