Anyone Know the Range of Upgraded DEVO 7E ?

I mostly Fly helicopters but after 250 racing quads came to the rc i bought one and now flying it.I want to try some long range fpv.I don't Know the signal strength of my moded devo 7e!!

1.Anyone know the range of your devo 7e with "Walkera S-Mod Module and 2DB Antena" ?
2.If anyone don't How do i Check Range?

Which protocol? Seems that there are big range differences with different protocols, from what I've read using only the stock module the devo protocol/RX's have the longer range

I am using DSMX.

".If anyone don't How do i Check Range? "

Do a ground check.
Set the transmitter to 100mW, place it at least at 1.5m height and walk with the receiver until it loses bind.

Edit: range on ground is lesser than in air. (Fresnel zone!)

Well try at 1mw output power and see if you can get about 60m with AR6210/AR8000 and <40 FrameLosses (low as possible, best 0).

Was successful on my Devo10@100mw DSMx.

Ground RangeTest (reduced output power) works on Spektrum DX8 up to ~60m with AR6210.
Not only 30-35m. So far my tests in 2013.

On my 7E I was always very sceptical of the range (after initially having a bad blocking diode only sending 3.xV to the stock module) so I always did a full power range test of every model (after replacing the diode). Note I fly DSMX using mostly orange, but also a few lemon rx's.

Anyway never once did I find a rx that didn't make 500 meters. A single antenna lemon sat would start to drop bits around 630m but any diversity DSMX / DSM2 receiver would make it well past 800m...

Check this out:

Resistor or Diode? That is the question... <-- Click here!

In my opinion, the component that is being referred to as a diode is in fact a 10k Ohm Resistor, not a diode. Checkout the photos with the component removed to be measured out of circuit. It was then reinstalled and bridged over with a thin wire and solder. This method allows it to be reverted back to original state if desired. Note, the EMI shield was first removed for the rework and reinstalled post mod using a solder rework station that incorporates concentrated hot air.

I hope this helps.

Here's some supporting measurements post mod on the stock module:

A more simple test in your environmental conditions would be to take a pall with you and go to a large field. Bind the TX to the RX of the model. Then begin a walk with your buddy remaining behind to monitor/save the model in the event an issue arises. If your setup supports it and this is applicable for the application, you may want to employ fail safe settings in the event of a lost signal. For example, apply full brake on a 4wd buggy/truggy when the RX loses signal. This works especially well for surface models.

I have checked mine 3m at 100uf.

What is your range at 1mw?

10m-15m.

Spektrum suggests ~30-35m.

Do you have any genuine Spektrum RX like AR600, AR6210, AR8000 + TM1100/TM1000?

I haven't.only 2 storm s603 rx. i mostly fly helicopters and stay with 200m range.because of that range is not a problem for me. but after i bought 250 racing drone to fpv flying range is the biggest problem for me.i have turn on tx without antenna many times.i think it must be the source of the range problem.
