Helo performance specs are not unlike a VW's diesel efficiency - results may vary in the real world.
If you want to do more, either buy one with more seats than you need or have thinner friends/pax. :E

Also performance problems?

hey skadi....that ain't no performance problem, note the comfortable HIGE; 'twas a Pilot management problem :ooh: (couldn't manage the machine correctly) :*

Guys
When looking at the graphs remember a few things. They were made by test pilots ( i.e. better than us ) trying to make it as good as possible ! With cleaned and polished blades and a new engine. So they are going to get a better figure than us mere mortals !

If You think the Crapinson 22 runs out of puff fast, try flying an H269 or a Franklin engined 47D
I always thought that the R22 (O-360, 131hp) has more power problems than the 269 (HIO-360, 190hp). Ok, the 269 has some 100kg more empty weight and some 300kg more MTOW, but under "normal" german summer conditions (about ISA+20), I´ve never experienced real problems in the 269, not even with me having 90kg and my TRE having some 120kg.

There is the 300C and the 300CB. The CB has less power.

Ah, ok. Only flew the C. No issues... ;-)

Wrong! Performance charts (Hover) are yes made based upon test pilot flights data but the skill to maintain a zero wind hover does not require a test pilot and the engine power at which the charts are made is the minimum spec power i.e. a fully deteriorated engine.
