8 Wessex Helis and Spares - No reserve auction
Gentleman Aviator
crab@
Wouldn't the computers have had to be different as the Wessex had static droop but the SK (not my type) I understand increases NR with pitch application.......
....... or is this just an internal "tweak"???
Must go and check the registrations to see how many of them I've flown .... spread across 3 logbooks and 2992 hours and 45 mins on type (always ped me off I didn't quite make 3K!)

Teeteringhead - the collective pitch anticipators (CPAs) modify the droop law in the computer and electically shift it to the right so the NR increases. If you lose the CPAs it reverts to normal static droop.
I need to check but I don't think I quite made 3K on Wessi either

Available again ... for the last time
The Wessex deal to Africa fell over last week (after 6 months of hard work on all sides) due to difficulties with the local aviation authority regarding these helis being used in restricted commercial ops
The first lot available is the 3 x HC Mk2s in Hixon , Staffordshire UK

The Wessex - blimey, what a fantastic, forgiving and built-like-a-brick-built-****e-house machine! The hours I spent abusing that wonderful design without coming unstuck bear tribute to it's strength and resilience.

We had a certain no-notice task to carry an USL that the Wessex couldn't lift. The trick was to get them to call "Buster" (= slow down we can't keep up) when we had the underslung load underneath and they were "clean" (or as clean as Walter Wessex could get).
Also, the RAF stopped supporting those "Nicaraguan" aircraft to a great extent in HK just prior to them being sold. It wasn't absolutely unusual to have one only serviceable, sometimes less. Once or twice 28 Sqn even had to ask for a favour from a civilian organisation to fly a trip..... of course, that organisation said yes.
Shame the RAF never bought the "SuperWessex" (Blackhawks) - the Wessex boys would have loved them (I did).

Have to agree with you Shy about the Blackhawk - felt like a grownup Wessex - even to the "three point" landing (tail right left) and having huge blindspots in the cockpit!
I never flew the RR engined Blackhawk, which I gather was even more awesome, as it continued the "do what you like with the collective and the Nr won't budge" theory of the Queen (Mother) of the Skies......

Remember being in The Province soon after we took Pumas there. A certain crewman with a penchant for sketching drew a Puma front end with a Wessex tail and main U/C. Said it would make a perfect SH machine. I remember when the Blackhawk first came out, it was almost exactly like that sketch - spooky! (OK, so a bit of thread creep).
I was told, years ago, that when Westlands were going to build the turbine engined S58 they proposed putting the engines and gearbox together in the same way as the Westminster and the cockpit would go where the engine was. It was rejected by the Services as they considered it was too dangerous to have the engines above the cabin in case of a crash. Donno how true it was, but that was what I was told. Shades of the twin Gnome Belverdere, wide and fat with two aft engines like the wokka.
TTHD,thought 3-pt. landing in Wx was `tail-left-right`,due t/r roll etc....and I know a 22 Nav trapper who managed to break a tailwheel off during a t/o or ldg.....!
Crab...the anticipator `tilts` the `droop slope` to the right,above the `knee` to give `droop cancelling`,and no `rate of change ` signal, as per Wx...unless it`s all changed! (RV1,2,3,?)
AS-AE,the h-p cocks are electrically operated and can stick between open/closed especially if you tried first start of the day without a GPU,/weak batteries,etc,so just batt, no1 computor,1 fuel pump to `prime` the line,then`off`, then start and open h-p at 5000rpm.If the PTIT rise normal,ok..if its heading for 400 fast,chop h-p/l-p,right off(fully off),otherwise,it`ll be expensive !!!
Are the `blue` computors Mk 1a s/2/3 ? as mk1a had problems with the initial response/transient droop if you pulled one back/engine failure.Comments ?Syc

Hi Sycamore
Spot on , the GPU wouldn't start and the battery cart was marginal
I don't know the answer to your question on the computers , I should be in the UK soon so I'll find out

XR520 I remember, fresh from winning Concours at the 83 Helimeet at MW.
