Actually, I'd say your english is quite good (I'm a native speaker).
Anyway, this is an intriguing aircraft...the fuselage especially looks very aerodynamically sound. However, it could have used some engine coweling...
But, I'm no expert on aerodynamics so I couldn't say.

This aircraft is the AT40 fitted with a 40HP Salmson engine. The AT35 was fitted with a 35HP Anzani engine. I suppose the AT35 became the AT40 after changing the engine. But I am not sure of this. I am the son of Paul Bourgois who built 3 aircraft like this. Unfortunatelly I was not born at that time, so I have not much information about this time. Please excuse my english as I am french. If you have any information about these aircraft please contact me.
