RE: Best plane for a cox .049
Grant:
If you have a Golden Bee .049, that's the one with a stunt tank that has one fill tube on top and one overflow tube on the bottom, get the Carl Goldberg "Little Satan", it's designed for it. It is a scaled down version of the .35 size Voodoo combat wing with a dual boom to mount a flying stab. It is a simple model to build with most of its strength dependant upon the beefy formed leading and trailing edges.
The key most important feature to heed in your building is OUTBOARD WING TIP WEIGHT. Don't forget to add it. The "Little Satan" has built in engine off set, so you can NOT avoid it; you need it also to keep the model at the end of the lines, but you also need outboard wing tip weight.
With outboard wing tip weight I have been able to run all around the grassy field as hard as I could even on windy days and still have that model stay tight on the 35 foot dacron lines.
