I would NEVER use 1/4" thick fins of ANY wood on a rocket this SMALL.
Most likely I would use epoxy mounted/filleted 3/16" Basswood or possibly 1/8" Aircraft-ply, either of which would hold up fine through H-power if it is not Warp-9 or V-max propellant.
Basswood is much easier to shape/finish than ply.

Yes, there is such a thing as NORMAL
, if you have to ask what is "NORMAL" , you probably aren't !

Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !
