your welcome Ron, i found out about the tank because i had a h9 alpha and arrow and gave the arrow to my son and he flew it and then bought a ucd 46 and wasnt thrilled about the flight time and thought he would just see and wa la, it fit perfect, so im having him bring me the other one for mine.

and for an update on my build, i came home early today to build and ive got it almost done, just need to hook up fuel lines,canopy,and.............hey im almost done
