We are just about ready to start up our new Thunderbolt 540 on out RV-10. Thinking we will start later tomorrow or maybe Sunday.. but might not fly this weekend.
Today?s high was 2F. This weekend isn?t going to be so terrible, but I?m still just wondering if there is anything I should do different for break in with it this cold out. I know to avoid shock cooling. I plan to descend by gentle power reductions to try to keep CHTs from dropping more than 50F per min.
I plan to run it had, as per the Lycoming instruction and keeping CHT as low as possible. But if CHT stays low, say under 400, can I run it too hard? 5000? msl right now might be 3000?DA here over next week.
Should I postpone flying in the extreme cold or use the cold to run the engine hard?
Next week the forecasts are showing highs still well below 0F.
