It appears that I'm not the only one who has doubts about this engine employing 4 valves per cylinder (unless that question mark was placed there by the person who wrote that section, because they weren't sure and made a guess at it). Every other radial engine I can think of is a 2-valve engine, for the same reason that almost all pushrod engines are 2-valve. It's almost impossible to make a workable system to actuate 4 valves with pushrods and rocker arms. — Preceding unsigned comment added by .45Colt (talk • contribs) 15:33, 11 February 2014 (UTC)Reply

The article on G5N states it flew for the first time on April 08, not April 10. 31.144.189.237 (talk) 12:15, 10 April 2025 (UTC)Reply

Francillon states that the G5N1 first flew in December 1939, see Wikipedia:Don't cite Wikipedia on Wikipedia. Nimbus (Cumulus nimbus floats by) 18:28, 10 April 2025 (UTC)Reply
