if you don't like the way it flies after.

i personnally don't think it's that hard to repair.

draw a line 1/8 " below the horizontal stab and cut.
cut the rudder's hinge from the fuselage

add tri to the inside of the fuselage
add a 1/8 thick piece of wood to build the 1/8 back up.
if the TE of the verticle stab (post) runs all the way down to the bottom of the fuselage,
drill a tooth pick or a dowl to rejoint it.

a dremel is nice to clean off the wood and epoxy from the bottom of the
horiziontal stab.

re center, re hinge rudder to fuse and epoxy.

add tri stock to the bottom of the coner the horizontal stab at fuselage to reinforce.
i do this anyways on 4 *s and most of my planes. it called for on a GP p51.

i also don't like the way the 4* .40 vertical stab is just sitting on top of the horizontal.
it'll get knock off. the surface of the wood will just crack, or peel, or the glue joint become
weak.
i lost a vertical stab in flight after a nose over on a Kwik Fly.
that was fun

i modify the stab to have a rear post and drill tooth picks into the bottom of the
vertical stab to joint to the horizontal stab.
