Full nose-down trim?
My prior aircraft was a very fast RV6. I once went into a major metro airport. Approach said they would need to hold me out for 20 minutes until things slowed down for arrivals since the flow was at 180 knots. I replied I could do 180 knots. He sequenced me right in and a few minutes later said, “wow you really are doing 180 knots”.
And 2790 rpm, cold oil and no fuel in the left tank.
You made Robbie proud that day!!!
