Failed Devo 7e S mod?

Hi all

I have just done this mod which involves removing the stock module and replacing it with the Devo 8s upgrade module . I have quadruple checked my connections and also ensured I haven't bridged anything.

When I turn on my Tx I am getting a low voltage warning regardless of whether or not I have fresh batteries or not. The level always shows as 2.98v.

Also I am getting less than 10m distance with my receiver. I haven't checked another as I only have the one.

It seems I have done something wrong?

can you take a photo of the pcb under the transmit module. im doing the ssame module but i lifted some of the pads.
and broken few track....

Sorry I'm not sure where you mean - could you highlight in one of my photos?

i need a close up between the rubber and contact pads.

Sorry for the delay - will this do?

Where did you get your Devo 8s upgrade module? It looks like I messed up with the range upgrade so I need a replacement for the stock module but I can't find the Devo 8s upgrade module anywhere (in stock) ..

From banggood. $20 for the module, aerial and cable.

Looks like it's not available anymore, product link 404s? www.banggood.com/Walkera-WK-DEVO-S-MOD-U...reviews-p922596.html

Looks like walkeraonline / ehirobo (exact same content/company) currently have them for US$20 with free (?) shipping

After several pleasurable months of flying my quad with my Flysky Tx, I realised that the Devo could be used as a USB controller for FPV Freerider.

However, this f'ing POS had the last laugh - not only does the upgraded module not work but whatever I did to it seems to have fried the USB as well. Windows knows that its there but doesn't recognise it. The USB Upgrade tool also refuses to see it.

So I guess that is really it. It is totally f*cked. Mind you now that I have been my current Tx for a while I can see that the Devo 7e really is a toy, so I'm not that worried. Its a p1sser about the money, but lesson learned - don't f*ck with things that don't need to be f*cked with.

Thanks for the walkeraonline link. US$24 for the module incl. shipping but less expensive than a new Devo 7E . It looks like this shop if one of the few they still have the module in stock so not too much choice .

Whoops I'd misread it as shipping free to your country, not shipping fee. Or maybe I came from a different page that had free shipping on a certain item, can't remember.
