Xochiyaoyotl Contest Trophy

Happy Cinco de Mayo!

Flying a Todi RC Sailplane at the 1973 Xochiyaoyotl contest in Mexico, Stuart Cornew won this trophy. It features a hand-carved miniature Diamant sailplane.

A bright yellow T-tailed Diamant sailplane is mounted onto a plastic base with an engraved plate.Can anyone translate the Spanish for us?

The engraved plate notes that this trophy was awarded at the Xochiyaoyotl contest in 1973. The Todi, this trophy, and several similar trophies were donated in 2013 by Stuart Cornew in honor of his father, Richard.
