Rotary Wing Pilots: "I've Always Wondered..."

There's a couple of things I'm curious about:

First, are there any helicopters in the world configured for "side stick" control for cyclic?

Second, and this is really just for any (former or present) gunship crews. When firing a powerful canon as on the AH-64, does one have to compensate with forward cyclic to balance "thrust" generated by the gun?
TIA and my advance apologies if anything I've asked is classified.

The front (gunner's) cockpit of the Bell Cobras has sidestick cyclic and collective, as the sight is in the center.

Quoting MCIGuy (Thread starter):
First, are there any helicopters in the world configured for "side stick" control for cyclic?

Older model AH-1 Cobras front seat gunners have a side stick control, however it has only limited authority and cannot be used for aggressive maneuvering. The latest AH-1 Zulu Cobra has full authority side stick control for the gunner (front seat) and the pilot (back seat).

Also the canceled Comanche had fly-by-wire side stick cyclic control front and back.

Sikorsky has been flying an experimental UH-60 modified with a side stick for years and plans to use side sticks on the S-92 when converted to fly-by-wire.

Have fun,

Aircraft design is just one big compromise,,,

One of the largest, the Sikorsky S-64 Skycrane has one.

The sidestick is mounted in the little aft-facing bubble shown in the second picture. The seat faces the hook, and slingloads. You can see it clearly in the second photo. Just above the green stripe. It reportedly twists left-right for anti-torque control as well. Clearly there are no pedals for that seat.

I have always wondered why in helicopters with a "Side-By-Side" crew up front, the PIC usually sits in the right seat as opposed to their fixed wing counterparts?

Yeah, I saw one up close at Pima (standing over the entryway). I saw the stick in the back and assumed it was for load control or something. Thanks! Smile

I'm pretty sure that the Boeing modified LightHawk from the 80s also had side stick cyclic in the front lower cockpit as well. This was the one with fiber optic flight controls.



Where are all of my respected members going?

The S-76 Shadow was flown with all kinds of combinations of single sidestick, dual sidestick, single sidestick with pedals, etc.:
