That's alright, Chuck. I made a mistake ounce myself. Watching them fly at the nats this year,it seemed that the flights lasted around 5 or 6 min. There's only so much you can do with a WWI bird.
No flaps, retracts, bomb bay doors, etc. I did add the bomb rack, and if this plane flies as well as the test plane, then I'll give them a loop. I didn't get a chance to time the engine yet, but I'll let you know how it goes.
