What are you waiting for? I told you the temp in post #2. Others backed it up, I find it interesting you ask us what something should be then tell us, well at least me, that we're wrong. Then in post #16 you say 200-220 is right which is what I've been saying all along. Why do you belive there's a difference between engine sizes? Worse case is you fly it and make up your own opinion and let us know. It'll be between 200 and 220 though....
