Thanks! How hot do you think? 180+ degrees?

Jeff,

I've never measured the water temperature; just hot tap water in a bowl.
Warm the fin and carefully bend/curl in the opposite direction hold 'till cool.
It may take a few tries.

Bob

I tried it with very hot water. It improved a little, but the plastic is showing some crazing from the stress of being flexed so I'll not go any further--especially since I would probably have to trade a kidney for another original clear plastic fin unit.

Thanks for the help.

Jeff,

You are welcome. Sorry it's not behaving; beats the old butyrate fins
as used on the Estes semi scale K-39 Saturn V, etc.

Bob
p.s. the Vixen should write a pamphlet on brush painting,
my stuff is crap in comparison..

Just get a kit with the black fin unit and "pirate" those for flight usage.

I can't speak to more recent releases, but Page 8 sheds some light on relevant older kits:

There was a ready-to-fly called the Sizzler in the 2010 time frame that had a bayonet mount black fin can of that sort. I might still have one or two of them around.
