Hard cases for Fr-SKY V8R7-II receiver
I sure like the vertical pins on the V8R7-II receiver.
I'm not so happy with its card stock outer covering.
I have installed two of them in old 72 mHz cases,
but I'm near the end of my stock of small cases.
What else can be used as a hard case for these receivers?

Did anyone ever noticed problems/interference from the two-way RX's into GPS receivers?
I was installing a OSD on my multicopter and as soon as I power the RX+TX the GPS signals drop quite substantially and most of the times it looses the 3D fix, if I turn off
the radio the 3D fix is regained.
The GPS is a rather recent one, uBlox 6 and eventually I ended up trying with a MTK 3329 only to get the same behaviour.
I know that the frequencies are not the same the uBlox works in L1 (1575.42Mhz) but it seems tha the telemetry downlink interferes.
Unfortunately the only one-way RX I have from Frsky I was never able to bind it so I can't test it to see how it behaves.

This Sunday flew an EZ* UAV where distances between all electronics are in the same ballpark as in a multicopter. No GPS harm noticed...

I searched around and couldn't find any references, as I'd assume that if it's happening to me it must have happened before to others. (unless the RX is bad)
I'm using a D4R-II, so I'll remove a D4FR from another quad and give it a try.

p.s. We will have both versions in stock for a short period, so if you want the 27ms, please let us know via email after placing your order.

I have spent about an hour trying to find out how to get telemetry set up for a glider. I have the following:
- FLY SKY 9x with ER9X
- FR Sky DJT module
- FSky FLD-02
- D8R-II Plus Rx
What else do I need to display lipo voltage? I tried seting it up but the user manual gives next to no clues on how to set up. Can anyone be so kind as to help or direct to existing posts? Many thanks.

Some basic queastions first:
Did you bind the receiver?
When you say LiPO voltage, exactly what are you referring to? Receiver voltage or actual LiPO voltage?
Can you get power to the FLD-02? Do you have it plugged into the module correctly?
Are you looking at the data screens or the Menu? You need to rock the button on the display to select data and then press it in to select.
For LiPO voltage, you would need the hub and the LiPO sensor. this gives you each cell's voltage.
If you are talking about receiver voltage:
When side port pins of A1 and X are connected by the jumper, A1 will change from external analog telemetry port to internal built-in battery voltage sensor.
A1 (internal): max voltage 3.3V, division ratio 4:1
Since the voltage is divided by 4, you can plug in a voltage up to 4 * 3.3 = 13.2 volts (assuming the receiver and servos can handle it).
Otherwise, you need a voltage divider dependant on your LiPO voltage and such that it brings the voltag down to 3.3 volts when fully charged. Do not forget to plud that divdor into either A1 or A2 and leave out the jumper (if using A1 to report the value. In the Menu section, you will also have to set the divider value to 4 if using the internal or to whatever amount you have constructed in your divider.
Does this help?

Ok.... So I also need the hub and voltage sensor.... I thought the rx gave the lipo voltage and you only needed the hub if you wanted the other fancy stuff. Sorry..... Ill order the hub and voltage sensor.
I see there are 2.... Which one do you guys recommend?

If you do want individual cells, then you use the FLVS, either the 01 (display) or 02 (no display).
You can either plug it into a hub or you can get a current sensor and plug into that (it accepts digital input from the FLVS).
You must have a receiver that accepts digital data, such as the one of the D8R versions or the D4R-II. The D6FR has only analog input.
By the way, I don't know if anyone said it yet, but Aloft Hobbies is the place to get stuff in North America and may even be a good source for you. Aloft gives genuinely useful advice if you ask for it.Also the price is right and shipping is fast and relatively cheap (here anyway).
