Thanks for sharing that!
I also bought my 2702 from Wow and what they gave me for a guide is not exactly what you received. I got a spreadsheet with typical ccpm settings for a computer radio and a photocopied excerpt from the V450D01 manual, but what was lacking was the "STEP 2" and "STEP 3" parts that are not part of the original manual.
Speaking of Wow, their price is $129.99 based on their claim of a $31.66 price increase that Walkera put to discourage the use of this receiver outside of their line of helis. That was so disingenuous just on its face:
Why would anyone want to discourage the appropriate use of their product when doing so leads to fewer sales?
That was just a money grab because you can get the same receiver here for $98.99...
(as a noob on this forum I was unable to post a link, but it is available at www dot oomodel dot com- just put "2702" into the search field at the very top and it will be the first listed result.)
Thanks again for sharing - now all of my cognitive dissonance has evaporated...
