Hi,



I just put the first hour of break in on my Nitro Z7 with 150 Pro XS. I have a couple questions:



1) For the first hour, I followed the book, varying the throttle every two minutes. Running trimmed down, I varied my RPM's from about 3000 to 4500 per the book. The speeds on the speedometer (didn't have my GPS hooked up yet) ranged from about 30 to 45 mph. Do those numbers sound right?



2) For the next three hours, the book says to vary speeds every 10 minutes. Do they mean "at least" 10 minutes? For example, is it even better to still vary the speeds every 2 minutes, or is there some reason that the motor is supposed to be kept at the same speed for a full 10 minutes?



I would appreciate any feedback. Thanks,



Mike
