I flew my 1-34R for three years and found that taping the rudder hinge on both
the inside and outside of the hinged side does very little to improve
efectiveness, unlike the ailerons where it helps alot. Make sure the fabric is
secured to the rudder and isn't loose, some people don't ribstich them. I now
have a SGS 1-23 and it has a little, ineffective rudder compared to the
1-34.Enjoy your ship its a great glider just heavy to assemble.
