Hello everyone. I have recently moved up from 1/2a to larger sized CL planes. The only one I currently own is a Skyray flying with a 25 La-S. It flies absolutely amazing. I love it. I decided to get the Giant king Pin from Black Hawk Models in the event that I crash the Skryay. I do not want to be caught without a large plane to fly. I have a McCoy 35 Red Head to use on it. Does anyone have suggestions on this plane or pictures/videos of one? Any suggestions on the engine? I have come to understand that the quality of some McCoys can be suspect. But when you find a runner it will last forever. My dad has a regular McCoy 35 that is definitely a runner. He told me that I could use it if I wanted. The fuel I use is 25% Castor 10% Nitro. When we finish burning through this gallon will will move to some 5% Nitro 25% Castor. We will still use the 10% Nitro for our RC engines. I love the amount of oil that is left behind. It makes me feel a lot better about my engine.
I have another question. Should the engine be tuned to the traditional 4-2-4 break for level flight and leaning out in a stunt or should it be a solid 4 for level flight and the 4-2-4 for stunts?

Set the engine where it is in a "cackle" on the ground. Bouncing between a 4 and 2. Once it is in the air, depending on prop load, plane weight, etc., it might go into a solid 4 cycle. You can then set the engine leaner or richer depending on if the "break" is satisfactory. Once the needle is set, change the prop to control airspeed. Typically a 10-6 is the prop to start with.
I happen to love the engine run of the McCoy Red Heads.
I have never had, nor seen, a Giant Kingpin in person, but I do have the Giant Stuntmaster and it flies really well!
