Hi Guys
My next plane is likely to be in the 70 to 80 inch wingspan size.
I have heard that some people are covering the hinge line on the control surfaces, how exactly is this done, can someone post some diagrams or photo's ?
Is it done for all control surfaces ?
Does it split or lift after time?
Will it restrict the movement of the control surfaces?
Your help would be most appreciated.

Thanks
Don
