How do i seal my hingline gaps? I know that in "conventional" planes (balsa ) i can use some sort of self adhesive tape. But one of my planes is a foamie with a foam rudder that is attached to the vertical stabilizer with almost a control surface long piece of higly adhesive tape.The problem is that the tape seals totally the gap at the left side , however at the right side there is still a 1/2" gap which i can not cover with the same tape bacause if i do the rudder will go "stiff" and wont turn either direction properly. What should i do?????? (the gap really disturbs the airflow).
