In my time in 705 all the 3s were straight booms with an electric start radial engine. Also only 1 set of hydraulics plus an ECU which gave you engine oil pressure laterally on the cyclic, the theory being we should be strong enough to pull the collective & push forward on the cyclic! Quite tricky!
I think the engine was a Wright Cyclone??
The 7 had twin hydraulics & basically wouldn't fly if both failed unless you had the strength of Arnie. The cartridge was prone to pop the little disc in the nose; in Borneo we found the Malaysian 10 cent coin fitted perfectly! To prevent hydraulicing, we had to crank the engine 72 times to make sure none of the cylinders were full of oil! Great fun!
