Finally the Maiden flight as come. I run 2 tank on ground to break in my new OS.32SX and make the two first flight rich with a 10X5 prop at 11 000rpm. Wow! My friend help me with the first hand launch... like a rocket, this little plane goes up in a seconde! The first flight was very tricky... my ailerons was so sensible, just a little push on the stick and it already done 3 rolls...
All other flight goes very well. Between each flight, I take time to tune my control and lean a bit the engine. Finally I changed my 10X5 prop for a 9X6... What the difference in speed. The 9X6 was running at 15 000 rpm (engine rich mixture, not fully roaded)...
The last 2 flight of the day (a total of 10) was with an 8X8 APC running at 15 250 rpm. I take time to tune the engine finally. Like a ballistic missile, hand launch at full throttle, goes exactly where I point it, with just a small tendency to roll left (engine torque), but disappear in a second when it takes speed.
Now, I will put some time on it, the provide hardware in ARF kit is not tough enough, the CA hinge break on the last flight, and the left elevator is broken under the monokote! Need to replace and revise.

Here some pic, before and after! I was making a low pass at full speed when I saw something wrong with the plane! I immediately reduce the speed and land. Every thing was ok, just need to replace all CA hinge on the plane...
