Hi friends! Thanks you for all replies!!

Grant, the tank is not pressurized and the bombs really were mounted on wrong way, as you said. I followed your advice and adjusted the bomb accurately as orders the manual, but the problem continued.

I had to escape of the standard setup of low speed mixture in carburator and closed the screw the maximum that I could. Here the things started to work. Anyway,I still did not fly the airplane and will need much help for future problems!

And Rcpilet,I will try the Perry a little more.If don´t work, I will follow you!!

Thanks guys!!
