No...

If it's easier for you to cut it out ....Then do so.
Just install new hinges right next to the old ones.

You can drill a little hole at the center of the elevertor. Glue thin ply on the bottom if you like..

sholve the music wire through the hole...bend it accordingly .
Make a 90 bend first before you put the music wire through the hole.

You can make a slot under the rudder with a drill bit and
just glue the music wire using epoxy.

Or use fuel tubbing .
Or use those linkage thing with ears that's on the airleron linkage.
The part that you screw up and down to adjust the airlerons throw.

Buy one of those tail wheel assembly... it's just a little bracket.
If you have a piece metal laiding around it'll do the samething......such as a Hack saw blade.

You put a wheel collar under the bracket..so the force/pressure is on the collar instead of the rudder.
The music wire in the kit is probably not long enough...just buy an extra music wire...it's $.50

Or you can just bend the music wire...(without using a wheel) and make a skid. Then just mount it under the fuselage.
Just make sure it's tall enough so the horizantal and elevator dosn't drag on the ground.
You know...the WWI aircraft don't have a tail wheel either.
You don't want to use a wheel if it's just a skid or not hook up to the rudder.
