Homebuilt Helicopters of New Zealand - Another Rotorway Type, the Scorpion Too

At this point I will take a diversion from our Rotorway Execs to post about our sole Rotorway Scorpion Too helicopter, which was registered early on but slightly later than the first Exec 90s.

The Scorpion Too was an earlier design of B J Schramm and featured a welded steel body and tailboom with a basic 2 seater cockpit.  It was powered by an earlier Rotorway engine, the RW 133 which was developed from the VW engine.  It developed 133 HP, which was pretty marginal for a 2 seat helicopter.

The specifications for the Scorpion Too are:  length 20 feet 3 inches (6.18 metres) and the rotor diameter was 24 feet (7.32 metres).  The empty weight was around 750 pounds (340 kg) and the MAUW was 1,200 pounds (544 Kg).  The cruise speed was around 78 knots and the rate of climb was 800 feet per minute at sea level).

The Scorpion Too formed the basis for the Rotorway Exec helicopter.

We have only has one Scorpion Too helicopter registered in New Zealand:  ZK-HSM (c/n AACA/620) which was registered to Daryl Travis and Grant Jeffreys of Kaiapoi on 22/6/83

Try as we might, we have not been able to find a photo of ZK-HSM so this is a representative photo. Can anyone out there supply a photo of it?  Or does anyone remember ever seeing it?

But we do know that it was assembled by Alan Minchner of Airmec Aviation at West Melton, and we also know that it made its first flight on 29/8/83.  It was registered for quite some time before being cancelled as revoked on 18/6/98.
