Scale Need advice on acceptable practices on splicing spars, etc.

[Steve Mc Donald]

I am building my first giant scale model ( 1/3 scale Balsa Super Cub) and am seeking advice on splicing, reinforcing, etc. Sometimes I run across a situation such as splicing a false spar or something similar and the plans do not call for any reinforcing but I think it would make things stronger by scabbing a piece over the splice as long as it don't interfere with anything else, is it proper to do so? Another situation that has arose is say the notch cut in a rib that the main spar goes into is not a tight fit is it ok to glue a one inch piece of 1/4" square balsa in the corner to reinforce the joint ? I know that every extra piece adds weight but I am of the opinion that I would not mind having my plane a little heavier knowing it is a little stronger. Any advice you experienced builders can give is appreciated.

First rule is light planes fly better than heavier ones..There are many good books on wooden aircraft construction. The EAA would be a good place to start.
