PilotU - from what I've seen, BN-2 cruise is 140-144 kts at MP 2350 and rpms 2350 (easy to remember, like the "65 knots for everything" advice.
).
Only other numbers I know are: flaps half (TO) limit 114 kts, flaps full (landing) limit 88 kts.
An oddity I've seen in Caribbean flights is a quick reduction in rpms very soon after TO (like at 500 feet) - I presume to keep EGT and oil temps lower in the hot climate.
