Non-standard control configuration
Hi all,
Was wondering if anyone knows of any helicopters that are out there (or that used to be out there) that had the controls configured so that the collective was operated by the pilots right hand and the cyclic in the left?
And if so was the transition difficult from the standard configuration.
Note: this does not include reaching across the cockpit in a dual control fitted machine

If you fly an enstrom you will spend quite a bit of time with left hand on cyclic as it is flown from the left seat. All the radio, altimeter etc need to be operated with the right one. If you want to operate the collective between the seats its there to use unless you want to use the middle seat. I find no problem flying it either way.

Don't go there! A number of experienced instructors have crashed while trying to fly 'wrong handed' (including a certain ex Shackleton pilot in a confined area!).

Not a very clear photo, but one that I took of the shared collective of the Sycamore at RAF Museum, Hendon:
plus one from Airliners.net:
Interesting that the throttle is set opposite ways in the two photos, I guess the collective must be located on different sides of the centre console as well. Any really old drivers have an answer?

Don't go there
My one and only engine stoppage occured while left hand on cyclic because right hand was otherwise occupied. I seem to recall lowering the right collective. It was necessary to swap hands on the way down to try and get it going again as the only start button is on the end of the left collective.
Heres a picture. The right collective goes where the centre cushion is.
Try setting that transponder while still holding the stick with the right hand!

I must work on that one: digital camera, I don't think so

Same as a Bell-47, except that I can't seem to get to grips with the left hand cyclic bit...

The 1st picture of the Sycamore with the single collective is reversed, the second picture is correct. Other Sycamores had twin collectives but the picture is of a HAR14 or the German equivalent.. The yellow rings are the trim wheels, the small lever is the rotor brake and what looks like a handbrake is one. The red knob is the slow-running cutout.
The throttle cam for the engine wasn’t ideal so as you raised the collective you had to roll on throttle initially but as you lurched into the hover with the old Leonides howling away at about 40 ins MAP you had to roll it off to stop the wooden blades flying off.
The technique in the RH seat was to put you hand on the top of the throttle so that the opening and closing was a natural wrist movement. In the LH seat you put your hand underneath the throttle to get the same action.
No hydraulics. Trim wheels operated force springs for the for & aft and lateral trim. C of G was corrected by a tank of water meth under the cockpit floor that could be pumped backwards and forwards to a tank in the tail boom. The tail boom had a thick leather pad on the starboard side to encourage the blades to bounce off it should the droop stops not engage.
Sit in the left hand seat of a 332 and fly it the cack-handed with HYD AP out and you have a rough idea of what it flew like.
Surprisingly instructers who spent most of their time in the left seat used to prefer to fly it solo from the same seat. The station display pilot used to do the whole show, real vertical torque turns, etc with some poor airman strapped into the right hand seat as ballast.

Guys, the photo is as I took it through the window of the Sycamore at RAF Museum Hendon. It's a bit too far for me to go back and take another, so if someone in London is passing by maybe they can check for me and see whether the two photo that I took are accurate or not? I took two, they're totally untouched by me (check the EXIF file at my website)
Photo 1
Photo 2
To add further to the discussion, this photo by Andrew Simpson show the Weston-super-Mare Sycamore with what appears to be a "normal" collective. It is also apparently positioned on the right hand side of the centre console, the same as the photos that I took at Hendon!

I know that your first picture is reversed because the yellow for and aft trim wheel which in your picture is in front of the red slow-running cut out was between the right hand seat and the consol. The cut out is over extended because it is probably disconnected from the Hobson fuel contol unit. Kosher....Honest...
There were 14 Marks of Sycamore with several different configurations in the cockpit. Some with twin collectives and at least one that was designed to be flown from the left hand seat but none were designed to be flown with the controls switched. It is possible that the Weston machine is LHS one by the positioning of the flight instruments but I would have thought that it was a full dual contol version because of the cut out in the right hand seat squab.
If you look at the conbined engine/Rrpm gauge (the one with the big green sector) on the German machine you will see that 3000 Engine RPM is eqivalent to 275 Rrpm. On the Weston aircraft it is only 225 Rrpm. That shows the difference between various Marks.
I have tried to think of some way of forgiving your camera. Trim wheel on the wrong side, if possible, collective upside down but even though aircraft at that time had stacks of built in Murphys I don't think so.

It almost brings tears to the eyes,or is it the sweat off the brow;have to agree with F-E-D, about the controls;early civvy Sycs. operated from the LHS with/without duals,and main instrument panel on left,then it changed to RHS and a central collective.Comfortable leather seats,wind down windows,manual trims and controls(a right bu%%^r if you didn`t get the trim pre-set for a hover and forgot the Cof G compensator was running the wrong way),steep turns,max rate turns-yes !,torque-turns,proper ones,`jump` take-off- over-rev to 300?,hoik the lever and hope you got 30 kts,before you touched down,otherwise,you got ground resonance and couldn`t get airborne,and then coming back to land on the `spots` outside the CFS crewroom(goofers gallery),and getting resonance every time you touched the ground,then landing back on the grass to ask for an instructor to come out !!Didn`t happen to me,of course,says he,modestly,because Paddy McL.....taught you all the tricks!Anyone remember JWP(Pranger` to his friends) bashing the t/r on a d/wind q/stop?Happy Days and we all grew more hair on our chests !! Anyway, better go and fit the 2-stage amber and put on the blue goggles for some sim. I/F in the Beemer ,ahhh,nostalgia,ain`t wot it used to be....Syc....amore..
