- The EL-7 is the earlier ekranolet prototype from V. Kolganov's team that led to the Ivolga EK-12.
- The file is a 16 × 12.7 × 4 m box. The EK-12's own length and span are not published in the sources found, so it is not modelled.
- Marked secondary (Russian popular-tech site).
- True size, no printing tolerance added. Only published numbers are used; anything not published is said so.
- Secondary source: the numbers come from a retailer or magazine copy of the maker's specification.
