I'm pretty sure you're right.
Most all R/C aircraft are built by the owners hand in some manner. The F-16 could be from a kit, the C-17 almost certainly is from scratch.
One of the last open houses at Glenview NAS, they displayed 3 F-18 Blue Angels R/C models with an R/C C-130 Angels support plane and a F-4 Phantom, all same scale. The day I couldn't go, they were apparently flown in formation by the owners.
