I am building a parkflyer-sized Telemaster. It is reduced in size from the original's 99" wingspan to only 36 1/2".
Framing up the wings.

When returning to a hobby after many years, some upgrades and service work is to be expected.
The battery tray is modified to mount the new battery securely. The old cells are in front of the transmitter on the table.

The power wiring is redone to make it easier to disconnect the battery and charge it outside the transmitter. The yellow connector was added to be able to use a standard 2-cell flight pack.

I have added some switches over the years. As I had the transmitter open for he power mods, I cleaned up the wiring mess caused by temporary changes becoming permanent. The thin wires were most of them under the lid here, but some were just taped on top of the plate.

Here is a shot of the transmitter as it looks when in use. I use long sticks held between thumb and index fingers rather than just the thumb to steer.

There is a lot of electronics to go into such a small plane. 6 servos, a speed controller, a 7-channel receiver, a switching battery elimination circuit as the 6 servos pull too much current for the circuits in the speed controller, a battery and a motor.

The wing is nearly finished. The servos need a bit of wiring as there are 4 of them in the wing.

Striped wires for signal, solid for current.

Hoerner tips of the droopy kind are being carved from balsa block.
PES_2018-08-03_14-54-29_105mm_ by merco_61, on Flickr
The tips are glued on and shaped. I have only used a knife so far, no files or sandpaper.

Some fiddly work with a soldering iron today... The contact block is 15.9X6.9 mm and there are 6 pins and 8 cables. This is for the connection to the wing servos.

The rest of the day was spent in redesigning the fuselage to fit a modern motor and battery and designing a mount for the landing gear.
Stabilizer today.

Fuselage sides are usually made on top of each other, so they are as perfect mirrors of each other as possible.

I use lots of pieces of scrap wood to avoid sticking pins through longerons.
PES_2018-08-08_13-51-43_24mm_ by merco_61, on Flickr
The longerons get lots of glue area where they attach to the sheet front of the fuselage.

The landing gear mount is starting to take shape. It is made from 3 birch plywood parts, 2 of them are glued together here.

The landing gear is now epoxied in the mount. The frames have their outside dimensions, time to use the drill press and fretsaw to remove as much as possible without weakening the structure.

This is so cool!!! Thanks for showing us all the work going on behind the scenes. I'll look forward to seeing some images of the finished product. I'd love to see some of the plane in action, but I imagine you'll be too busy flying to photograph it! xD
So roughly how long does it take to build, from start to finish?
