Cool.. I've been told to run 5% nitro/22%oil (castor only) for break-in on the .65 sportster and after break-in no more than 10% nitro and still 22% oil... sound about right?
Yes
The K&B .65 sportster is a plane bearing engine and like a lot of castor oil.
They also tend to leak a little oil out of the front bushing area just behind the prop driver.
They have a hand chromed aluminum piston, and an aluminum cylinder, with No Liner,which is backwards form most R/C engines that have nickel or chromed cylinder sleeves and an aluminum piston.
Break it in and go have fun with it.
