Hi Op

Usually a lurker around these parts but I see you're not having much response so....

Take off -
Boost pump on
Flaps 15
Full fine full power
Rotate 65 kts (70 if crosswind) Will actually fly itself off with limited back pressure.
Gear up
300' Flaps up/check t/p's
500' - 25/2500/boost pump off/monitor fuel pressure
Climb out - 95kts
Overclimb cruise ht by 50', Close cowls and descend back to cruise to enable faster acceleration.
Leave setting at 25/2500 until a/c hits approx 125kts.
Set Cruise power - 23/2400
Lean
(Skip last 2 items if doing ccts and go straight to 20/2400 @ cct ht)

Descent -
20/2400
500 fpm
Enrich via couple of turns every 1000'

Approach -
As you said - a very slippery little sucker - hard to slow down in time for finals if you're not ahead of it, especially if descending into the circuit.
Best way to decelerate is dropping the gear - but you can't do that until IAS is down to 133 kts so be thinking ahead in this regard. Best to get your speed sussed well before joining cct.

Downwind -
BUMFH Checks, including fuel boost on @ F.
Turning base - Reduce MAP to 13"
Established on base -
Flaps 15 whilst backtrimming
80 kts

Finals
PUFF checks (Pitch full fine/U-C down & confirmed/Cowls open/Flaps Full whilst backtrimming)
Established @ 70 kts.
Round out/power off & float her down, keeping nose up. If you balloon to much then do a go around.

Important Notes:

Prop strikes are relatively easy. Never nose down after roundout as you may/probably will end up doing a wheelbarrow and inevitable propstrike.

Don't try and salvage an approach if not established by mid final - Go around. Yes I know this should be the case for all a/c but some moreso than others.

Give it plenty of right rudder on a go around lest you become a victim of the dreaded P factor and end up a smoking hole in the ground.

If you overshoot the c/line turning final do not over correct as you may also end up a smoking hole in the ground via low speed stall/spin.


Going from memory so may have missed a couple of points but hope this helps.
