I don't think the motor would quit if the lines go slack. Maybe it is a good thing if it is that slack, it won't hit so hard.
Test it all and make sure it all works the way it is supposed to.
I still have scars down the inside of both my forearms in different places where I reached around the prop to try and "tweak it" just a tad more. Most of these were nylon props on old school 1/2As. Think about a modern high tech prop on a modern motor... Guys with hooks for hands aren't really all that cool.

You probably had a reedie, they needed tweaking about three times in the middle of a flight too.

Aspeed, are you saying reedies don't run well with a bladder? I've read on Cox Forums where someone was setting up a reedie for bladder feed, but no one ever followed up with how it actually worked. It was going to be for a Killer Bee. At least if the engine dies, most of the flow probably just runs out the back and less into the crankcase.

It is ok with a bladder. I have seen it done many moons ago with a 1/8" hole in a BBee, and it worked for a few flights then. Just a stock BBee or Golden Bee or silver or pink or whatever always seem to go rich to lean at the end of the tank on suction.

Ok, I did a pic. of the "Little Red Caps" beside a regular bladder. I use tie wraps and the $5 tool to tighten them. It has an adjustable tension. The little red caps are about $5 for 20, and are used for caulking guns. I got mine at Lee Valley Tools, I don't know who else may have them. They are like little kitten condoms and have less pressure than a regular bladder.

Yep. Pressure feed usually cuts out with no great variation at end of run, one reason Jim Walker liked using it.
The Fireball plans explain how to make a balloon tank with a toy balloon from the 5 and 10 cent store, and the Walker pressure regulator was the ultimate add on- they still show up on eBay and elsewhere today.
The more things change, the more they stay the same.

They used to run a real neat "Jim Walker" multi-task C/L event up in Canada, don't know if they still do or not.

Cox .049s- others also. The McCoy .35 with the TF nylon prop was no slouch either.

Maybe they have those at Lowes or my little neighborhood HW store. I'll see if I can find some.

The Jim Walker event was cancelled last year around here, but came back by popular demand this year. Paul Smith (Detroit) won the last one I saw with a Nelson and a shutoff.

Unlikely at Lowe's, but try Ace or Tru-Value.
