Anemic climb rate CURE...
I'll add one more thing to Ernie's description of the 'anemic' climb rate, but on a more 'positive climb rate' note: the clam-bucket shaped rear gear doors are the BIG problem area and RT Aerospace has an excellent cure for this anemic problem. Remove those two doors, eliminate a couple of hydraulic actuators and hoses, and the 337 no longer has this problem, plus, the gear sucks up quicker and extends quicker. It's still an 'emergency' with one-engine out if you're beyond the accelerate-stop distance, but at least with the no-doors kit you won't get sucked down when cleaning up the gear before reaching best single-engine rate of climb speed, which is 89 KIAS.
Our P337 with R/STOL has the RTA kit installed and there is no longer any waiting until best climb speed is attained before bringing the gear up. Most of the time when we're off the ground at 44 Knots, up comes the gear, accelerating climb and airspeed. Of course, at full gross we're a little more conservative. We each have our own picadillos, and mine happens to be as much altitude and airspeed as possible when near the ground at takeoff...
