Please try to avoid taking off with Flaps in a Twin Comanche. They make it nearly impossible to lift off above Vmc.
I found an even better reason once. The flaps are retracted by independent springs. So at 300 feet or so after take-off with flap 15, you command flaps up, and only one retracts. The aircraft remains controllable in that state, but it's not my choice of configuration on a high-workload departure.
(BTW, solution is to extend flap to 15 again, reduce airspeed, and retract again.)
