Those tests on the MP Jet all look pretty good, but are run on 40 & 50% nitro with an .049 size prop on an .06. Good nonetheless. The diesel pulls a 7-3 quite well. I also have enough motors to last a couple lifetimes, but some I do not run because I am afraid of not getting parts when they blow up. Swap meets are great though, there are millions of motors out there. Profi and Fora are my choices for fun. Just flew my F2D combat again and am really amazed how they go. I wonder how the guys can even fly them together. Once it is overhead, I just kind of hope it will get down where I can see it again. I haven't run the Fora .049 yet, there is no throttle for regular flying, and and no good way to use a muffler for my rc field. I think a Profi might have been a better choice.
