Watch the CG
While the airplane does fly very well, you have to be careful of the CG limitations if it is one of the short models (Not Chieftain). Do your weight and balance carefully for takeoff and landing. Remember the outboards have a different moment arm than the inboards, so you will need to determine how you will burn fuel so you can correctly calculate your landing W&B. It can make a difference. Lightly loaded I have to put 100 lbs of sand in the aft cargo area to keep it within CG. To me it flies more like an Aztec than a Seneca. It lands easier than a Seneca, too. Very stable and straight forward to fly. Pretty good on one engine, but the single engine missed approach is a bear. I've never flown the 310 h.p. model, though, only the 325 CR and the Chieftain. Study the POH and take your time. You'll have a blast!
