cox extra 300s
 

my friend gave me this plane which he bought for a dollar at a yard sale for me to fix it. its missing a prop and the control wire. i think i can make a wire with string and a handle, but i need to know what size prop the 049 engines use. can i use any prop out there, like electric plane props?
thanks

5x3, 5x4, or 6x3 work well on 1/2A's. String will work for 1/2A's as long as it will hold up. I just use .008 control lines.
