This doesn't completely get rid of the need for a lot of servos but these ones are cheaper

You could use just a couple linear servos to raise and lower the entire pin art toy up and down and use 14 servos underneath to move the individual segments into place.
If you don't want to go this route, I don't know if you have access to other materials or a 3D printer, but you could construct something like this

and use one rotational servo for each number and do the same thing where you raise and lower the entire pin art.
Its probably worth it to get a decent transmitter. I would personally recommend the Taranis Qx7 but you could also buy a Spektrum Dx6 or a FlySky-I6. Keep in mind these use different protocols so make sure to get a compatible reciever.
A word about flitetest: Their power packs and speed build kits are kind of expensive as they use drone motors, waterproof foam board, and laser cutting. Their construction methods, while they make great flying planes, they are a bit involved (require curved, symmetrical cuts, a folding, sometimes soldering skill), and they are not durable in my experience (particularly their wings). For example, the Storch with PP-C would run $100. You can build a plane for ~$60 using Experimental Airlines methods(Not including reusable stuff like Transmitter and batteries).
I stared with an Experimental Airlines Noobtube and I would recommend either this plane or the EA Axon for any beginner. The Noobtube is a bit fast and has a front mounted propeller, though.
As far as gear, here are some components I personally use:
30A ESC
Turnigy 2826-6 2200kv
9g Servos ($1.80 each!)
Pushrods
6x4 props or even a 3-blade 6x4.
A couple more things you may find useful: servo wire extenders, landing gear, gift cards, and duct tape.
Hmm, can you give more detail on your clock?
I expect that 42 servos is 7 segments * 6 digits. It that your plan?
Typically cost $5 or more each, which makes your idea $$$

I did a quick search and found this link, I can't vouch for the part or the vendor
.
https://www.amazon.com/Micro-Helicopter-Airplane-Remote-Control/dp/B072V529YD
You can get 10 pieces for $18, less than $2 each
I really like this line -- Sold by Miuzeipro and Fulfilled by Amazon.

Maybe these links will be useful as well

You will need some type of servo driver board. I suggest Adafruit or Sparkfun
