The under-sides of the wings and stabilizer/elevator remain translucent off-white.

All main components have been covered and mostly painted.

A little more paint to go, followed by receiver/gyro-stabilizer/throttle installation.

Then some basic assembly.

Hello,

Welcome to the hobby - I hope you find it as exciting as I do!

I am likely the least qualified to give you an opinion!  I only received my wings about a year ago.  I learned on an Apprentice [well, actually two Apprentices - I crashed and repaired the first one so many times it got beyond being airworthy and the parts were harvested and transplanted into other planes   :)  ]
I use a 3300 mAh battery.  The Apprentice is capable of at least a 10 minute flight with that battery - however my "nerves" always run out before the battery!  Ten minutes of hyper-focused concentration is a LONG time!  I rarely fly more than about 7 minutes.  While training my usual routine was: fly, land, pause, settle, pee, replace the battery, repeat.
In my opinion, better to have a few batteries that will give you 7 minutes than one that will give you 15 minutes. Sure, one can reuse the battery for several flights, but I prefer to change it after each flight. I would typically have 4 charged batteries at the field and, for me, that was enough!
Likely some of the more experienced fliers will have a different opinion, but there are my thoughts!

FWIW, it already does do this :)

I could not get the landing gear to bolt solidly to the retract pin with 3mm machine screws.  They slide around even when taxiing a bit.
I've wanted to try threaded inserts for a while and got some and some attachments for my soldering iron.
The inserts melted into the PLA in about 1 second.
The retract pin is 4mm so I put a 4mm steel rod into the landing gear to ensure I didn't go too far when putting in the threaded insert.
Then, instead of using a machine screw I used a set screw.  With a bit of Loctite I can really tighten the gear on now without fear of stripping PLA threads.
I feel using a threaded insert and a set screw may solve this issue with 3D printed landing gear.
The threaded insert is 3mm x H4.  It is 4mm in length and 4.2mm in diameter.  After they were installed I screwed in a long 3mm bolt and tried very hard to pull the insert out.  It wouldn't budge.
We'll see how it all does on grass.
