Can we just be clear on this:
The Play Store is installed on the ST-16, but does not work. This is 'intentional' by Yuneec, and trying to fix it risks breaking other software on the ST-16.
I really wouldn't recommend trying to install or update the Play Store on the ST-16. It's part of the firmware that Yuneec installs and has always been there and 'broken'. This isn't so unusual, as getting a fully licensed and validated Play Store installation is a lengthy and expensive process. It is possible that Yuneec may fix it in later firmware releases.
Note also that any changes you make are likely to be overwritten by Yuneec firmware releases. In the case of Play Store that will break the store itself, but will often also break apps installed with the play store.
