thanks a lot for the help guys you have been very kind ,i'll try to find an engine here in my country and add the fuselage ,to see what i can work on,i also thought about buying first one of those cheap models like the ones that i have seen for 45 dollars to get more or less the hang of it ,and after sometime(working) i might get some extra money so that i can spend and begin the challenge.!!!

thanks guys
any other help will be welcome
