Here's my complete RC build history, starting in 1977.
The border color of each photo in the list indicates how the plane was powered:

I number my planes in the order in which they're flown, not built. Some planes have taken a few hours to build, others a few years.

I've built and owned more planes that do not appear on my list, they either were built by me and never flown, or purchased. For example:

Scaled Composites White Knight and Space Ship One, built in 2005, never flown	Sig 4-Star 60, built by a fellow club member	A modified Trainer 40, designated "J4" as the fourth plane in the club's Joker's Wild Air Show Team. My callsign was "Hammer"
A scratch-built plane built by a fellow club member. He named it "Feather Merchant", my daughter named it "The Fish".	Heli-Max 1SQ V-Cam quadcopter, radio-controlled on 2.4 gHz.	An Ace GLH2 in 2003.
A foamboard delta built by my son in 2011 with my guidance.	A foamboard delta built by my other son in 2015 with my guidance.

I also maintain an Excel spreadsheet that records details and measurements of all my planes.
