well so much for my grand scheme to use my 7E for more than just my Super CP... Looks like it would have been equally smart to just go for the Nano CP X with the DX4E - the 7E while programmable is almost just as limited as the DX4E in that it's only good for small heli's and really short range... Looks like I'll still need to buy a DX6i eventually now anyway.

To get the full 7mw of the Devo7e module. Make sure to set within DeviationX software to the 150mw setting. There was a post on by PhractureredBlue about that.

I don't have a Devo so I can't direct you directly.

Thanks for posting your test results. It's a bit of an eye opener, isn't it?
When you consider the types of helis this radio comes bundled with, from the factory, it's a real cause for concern. e.g. Master CP, Hoten, 450d03 and other larger rigs.
Buyers , especially those new to the hobby, believe that the radio that comes in an rtf, must at the least be up to the job, if not marvelous in other aspects. However, the cold light of reality reveals another truth.

If you eventually get a Dx6i, I don't think you'll be disappointed. It is an excellent radio.

You can remove the plastic antenna cover if you open up the tx, then just have the antenna wire hanging out loose. Wouldn't recommend it though, as you can get dirt/moisture inside the tx then.

What sucks is that the previous Devo 7 has a much stronger transmission.

The 7 _IS_ a full size TX though, the 7E is more like an advanced programmable toy TX; plastic gimbals, sticks, fewer switches, etc.
It's really aimed at the indoor market rather than flying larger stuff outside. I mean... flying an LB at 50m away I don't know how you manage to keep orientation - even with LEDs attached...
If you want to fly outdoors then I think you have to have a fullsize TX really - the worst thing is that they bundle it with the 450D03, but flying a master in a baseball diamond is reasonable.

If I may also add a comment regarding the Devo 7, although definitely an improvement over the 7E's output power, it's not significantly higher.
The docs show 13 dBm (20mW). Forum member Hajile did some range testing with the 7 and found that the signal was okay out to 80m, beyond that it became hit and miss.
He made a thread about it here.

Full batts in Tx and model, 50 degrees F & humidity at 22%. This with Tx on the ground and me walking away in straight line of sight. I wonder if I can use this antenna wire, whatever there is stuffed in the cute little plastic housing, and get it at 90 degrees up, down or sideways to the model.
Actually if the tx was higher, it would probably give better range.
Not much, but should be better...

I was hoping to use it on an Armattan quad with the RX701 but will seriously reconsider now. I may get the Rx and do it anyway, it's not like I'd be flying the Armattan great distances away till I get used to it anyway, since I already have the radio that is.

@mono - where are you getting access to those docs for actual numbers?

@BD - I think mono was quoting from the FCC docs.

FYI, while I haven't tried it myself, I believe a Devo8s module when connected properly will give full range on a Devo7e. The Devo7e transmits at max power all the time as far as I can tell, so you'd be running between 100 and 150mW with the stock firmware (due to rolloff, it is not clear exactly what you'd get, and I don't have any way to do precise measurements).
You would need to replace the antenna at the same time though. If I were to do it, I'd definitely switch to Deviation at the same time (well, I already am running it so we're not really talking about me here), because running at max power all the time is rude to others using the 2.4GHz spectrum if you don't need to.

Just to make sure I'm on the same page...the 7E transmits at 100-150mW with stock firmware standalone or with stock firmware and the 8s module?

Without any module mod your stuck at 7mw with official and deviation firmware.
