How about with a pilot and some fuel on board?
PF, I usually fly my V35B with full fuel and one-up. At that loading is will consistently do 10,000 in 10 min at 2500/25" and 110 IAS. At gross TOW it takes about 12 min.
I always thought it was a homesick angel anyway
Hmmm, I always seem to mess up my metaphors!
