Range Testing my DX8

[Nige]

I was not happy with my tests on Sunday on using the range test mode at 30 paces with the telemetry enabled, it was showing lots of frame loss, I rebound my DSX12 to the model and flew as normal.

Today I did a direct comparison with my DSX12 using a flight log. The test machine was my Trex 600 with an AR9000 rx that I have been flying with my DSX12 for at least a year. It was sat on a picnic table side on, the aerial on both transmitters was in the same position.

First at 25 paces with the DX8 in range test mode
Fades A 27 B 18 R 45
Frame losses 209!!
Holds 0

With the DSX12 at 25 paces with range test button pressed.
Fades A 32 B 11 R 45
Frame losses 0
Holds 0

With the DX8 at full power and walking away as far as our field would allow.
Fades A 0 B 55 R 5
Frame Losses 3
Hold 0

Does not give me much confidence in the DX8. I wonder if the power output of the two transmitters are different in range test mode?

Anyone done a similar check?

Interesting read. Seams like we could do with some comparisons here. Wonder how the DX7 fairs?

More Data

I took more data today using the AR8000 that came with the DX8. The Rx was in a small card box to keep the aerials in a constant position. The Tx and aerials were always held in the same position. At 30 paces (using a marker) in range test mode.


Transmitter, Fades A, Fades r, Frame losses, Holds
DSX12, 45, 45, 0, 0
DX7, 45, 45, 0, 0
DX8, 90, 151, 5, 0

Recommended <100, <100, 0, 0
to pass range check

I have therefore concluded that it has failed the range check for second time and will send it in for a check up.
