The QRP Labs QMX Multimode Multiband QRP transceiver kit is an amazing combination of performance, features and low price in a very compact package. We have at the time of this video production, assembled something like 60-70 QMX transceivers here at QRP Labs Towers. This video contains my observations of some common pitfalls to avoid, and tips for successful assembly.
Some of the 52 tips may be obvious to you, many are in the assembly manual (which of course you will read word to word, cover to cover); but I suspect the majority of constructors will find at least something useful in the video. QMX is a compact build. With care and attention to detail, you should achieve a functioning, high performance transceiver.
I also created a Playlist of official QMX videos (though there are lots of other QMX videos too):
