After a lot of nervous knee-knocking, own-design Potez 'Dunkerque' was Finished, Fotographed, and Flown Almost without a hitch. She exhibited a little instability at full power while climbing out but is fine at 3/4 throttle or less. I'm very happy! Youtube :

Potez 621 Maiden Flight (1 min 49 sec)

After the stress of the Potez and Albatros builds, a little IPS Pfalz EI was built and flown in about a week. Absolutely no problems - a testament to a simple, straightforward design by Peter Rake.
