Ron -- while the remote release is a nice-to-have, is it truly required?
Not REQUIRED required, if you catch my drift. It's a nice thing to have.
Dan posted a good, safe sequence that he uses for starting his own airplane. As was also mentioned, climbing into to a Fly Baby after start is a bit more complex than your typical high-wing antique. I inadvertently started N500F at full throttle once, and it seemed to take forever getting around the wingtip to throttle back.
What a remote release gives is convenience, and with convenience, there's less chance that you won't tie down the plane before flipping the prop ("Weather's coming in, I don't want to have to go back and forth to untie the tail, I'll just prop it free-standing...")
I kept a hank of rope in the baggage compartment, but only had to use it once in the ~7 years I flew the original Fly Baby. I had a rope tied to a hangar stanchion for starting at home. When flying to other airports, I usually parked in a transient spot where there were tiedown ropes. When I got ready to go, I'd tie a loop in the end of one, slip it into the hook, pull the plane forward, start the engine, climb in and bolt myself down, wave off the observer who's trying to tell me the taill was still tied down, then pull the release when I was ready to taxi.
I always pull-tested the tiedown ropes before using them, and that's the one time I ended up using my own. The tiedowns at this airport were sun-bleached and broke with a moderate tug. I pulled out my knife, cut off ten feet of rope, tied the tail down, and started the engine. No big deal.
There's only twice that I wasn't able to tie down. Once was when the engine quit on final on a 15-degree day. Rolled onto the taxiway, but there wasn't any real way to tie it down. Check throttle, check throttle, flip, climb in and go. The second time was visiting a grass strip where the owner (who normally started me when I visited) turned out to not be home. I was 100 feet from the nearest tree, across a dirt road. Check throttle, check throttle, flip, and go.
In short, the remote-release hook is a great aid, but don't make it a required piece of equipment when you're shopping for a Fly Baby. After you own it, you can buy or build one.
