No they didn't - The HAR3's when I was on 705 were all with modded tails and had P&W engines but the HAS7 had the Leonides. I seem to remember it being much easier to fly than the HAS7 from the point of view of collective/throttle correlation. With the HAS7 in the cruise you were on the point of the cam and RRPM control was much more difficult than on the HAR3.
Also on the 7 you could close the throttle to idle to do a practice EOL but on the 3 you had to be really sure of getting to the spot for a practice EOL as the engine actually had to be shut down as if left at idle it would increase engine RPM when you raised the collective. HAS7 was cartridge start but for the life of me I can't remember what it was on the HAR3. Must have been electric start but the mind has gone blank after nearly 50 years!.
