 |  Flat vertical stab/rudder question.
I have an 87" Edge 540T. It has airfoil shaped horizontal stabs. But a flat vertical fin. Weird I Know!!! My question is should I brace it in any way? Maybe flying wires or something else?

No ones answered your question Paul so I will. It should be fine so long as the wood is good quality and well glued to the rest of the fuse. Some tests you can do are try the twist the fin left and right with the rudder attached and try moving the fin laterally (side to side) with one person holding the tail tube. This will give you a good idea of its strength. The rudder will add considerable strength to the whole thing. Minor flex is a good thing as it displaces load. |

The flat fin should be fine unless it just feels weak and wobbly. IMO flying wires are only used to brace the horizontal flat stabs. You can always add them for peace of mind I guess, but I've never heard of a vert. stab breaking unless it hits something hard. Good luck with your new plane.
