The military and civil operators had perpetual trouble with the engines which were considered complex.
[5] The CC-106 had its Elands replaced with the Allison T56 turboprop and the CV540 was re-engined with the Pratt & Whitney R-2800 Double Wasp piston engine.
Potential production applications which were subsequently cancelled were the Westland Westminster heavy-lift helicopter and the Fairey Rotodyne gyrodyne.
The Rotodyne operated as an autogyro in forward flight using the Eland turboprops.
For vertical flight the rotor was driven using an auxiliary compressor clutched to each Eland.
