Fighter Engine Start Comparison

God, I'm exhausted! I gave up after the first time cranking that bastard, and let Frank try it. He and Johnny were the ones that finally got it started, though. I see that a letter stated that the Jumo engine was a real SOB to start and talked about 109s going to electric starters. The German ground crews must have had shoulders like weight lifters!

They must be missing a trick; you could never effectively scramble an aircraft which was so hard to start.

As for the P51 comment; The Hurricane cleared the road, The Spitfire helped, and the P51 upgraded it to a motorway later on.

The Rolls-Royce Merlin won the war!

I think it might have been more of a logistics thing than anything else. Cartridge starters were pretty reliable, the cartridges are small (almost identical to a 12 gauge shotgun shell), you just need to have them on hand to make the system work. Electric starters require electricity and the batteries of that era were no where near as durable nor did they have the amperage of today's batteries, so an external electrical source may have been a requirement for starting if the engine did not fire up after a few attempts. The hand cranked starter required a crank and one or two men, pretty simple and one crank might fit every aircraft in the inventory.

As for weight savings, electric motors do not weigh a whole lot and many still rely upon a flywheel to get the engine rotating.

Electric starters on the Russian front? I don't think so!
