Cox Engine Breaking In #2

brand new cox engine for my rc plane just burning a few tanks off…

running on 10% nitro.

thought it was going to be very loud but wasnt as loud as i thought it would be but still i had to put ear plugs in as the first tank hurt my ears. you dont see much of these engines any more, they are a good engine if you take care of them.
