German forum, a poster has linked to a Yuneec EU Tweet stating
that the new H+ C23 camera will not be backwards compatible.

But there is chat about making the similar E90 cam compatible with the H instead.
They are also flagging up the EU provisional price for the new H+, which at EU€1549 (currently UK£1370 or US$1896) makes a lot more sense than the bloated UK£1679 currently being quoted by Yuneec UK.
In which case, I will be ordering mine from Germany.
