I don't think the EC130 or AS350 are comparable at all ... Maybe the EC120 or 206 . When the 505 comes out it will make the R66 look stupid re costs etc .
Personally I don't like any of the Robinson products and would fly a 480B , 206 or MD500 which are all far better and safer machines in my view and would all be significantly cheaper if you are only doing under 150 hrs a year . Even my A109 would be cheaper than the figures shown !!!!!

if it is them
 

I had a hunch so checked.
It looks like their accounts for year end 2014 are overdue.
It also looks like they have lost their auditor too.
These are sometimes danger signs for the welfare of a company.
Can anyone shed any light on this? Any cause for concern?

No idea about what is considered "Fair" in the UK but here in NZ the normal standard for type ratings is to pay an hourly rate for the Aircraft and then an hourly rate for the instructor(s) for both ground and flying time.

I did an R66 rating recently and it took a little over a morning including both ground instruction and the time in the air. I had about .5 in the 66 previously and had read the manual thoroughly but felt the type rating was fairly swift but comprehensive enough. 2 days just in ground school seems a lot especially if you have a bit of experience and are current in the 44.

R66 TR in Switzerland
 

Here's a breakdown of the cost in Switzerland (mountainflyers.ch) for comparison.


Ground course: 260 CHF (this price is of course for a course with a group of people, one full day)
Flight time: 1360 CHF /hr of actual flight time w/instructor, including 1 landing fee (-> 1225 CHF per rotor-turning hour if you assume 6min for startup/shutdown). Also, the instructors part of 150 CHF is not charged on the checkride flight.
FOCA examiner: 230 CHF
No VAT levied on training


So for 5hrs RTT training + 1hr RTT checkride, it would add up to:
260 + 5*1225 + 1075 + 230 = 7690 CHF
With the current exchange rate, this would correspond to 5.000 GBP.

Rip off conversions will not last much longer !!! .Very little UK sales if any since the great EASA approval deemed to be a saviour. Obviously everyone has wised up. Now at £600k a pop sales will surely be slow.
