By increasing the aileron length, this would also increase the roll rate. The increased roll rate would put extra stress on the tail surfaces during maneuvers. How do you know when to add flying wires? (I've never got a straight answer on this)
And most probably you never will get a straight answer. From my experience with other models with similar tail contruction, the tail of the Skybolt should be strong enough. But remember, that's only my opinion. If you feel otherwise you can of course add flying wires.
You were not kidding about this being a "challenging" model to build. The cabanes set up looks like it will raise my skill level. Any suggestions on how to ease the assembly of this?
Have you had a look at this: [link=http://www.airfieldmodels.com/information_source/how_to_articles_for_model_builders/construction/cabanes/index.htm](cabanes)[/link]
The best solution usually is to make some kind of jig and measure twice before soldering the thing together.
