sagy,
On my HUET "Statement of attainment" from RHO, March 2009, the 'lead RTO' is ERGT Australia, RTO 2534.
Good course (aren't they all?), but the relatively small cabin took some getting used to if you've done dunkers before. Apparently the size is somewhat dictated by the requirement to knock it down into a flat pack (or similar) for easy transport, but is really pretty cosy and is for just two crew.
Hope that helps
