Saito Fg 21 Smoke Four Stroke Gasoline Seagull models Christen Eagle RC aerobatic plane test flight

Good day,
this Seagull Christen Eagle RC plane is powered by a very nice running Saito FG 21 Four Stroke gasoline engine. An 2S electric Powerbox Smoke Pump adjusted to 25 % flow injecting Blue Max Smoke Oil into the exhaust manifold close to the cylinder. The white puffs of smoke look so beautiful in the sunshine. Enjoy and greetings from FMC Kinzigtal RC Flying Club in Germany.
