furyus,

After reading your previous posts and careful consideration I think you should forget the kit and simply start a scratch building project!!!!!!!!!!!!!!!

Look the the worst that can happen is that you are out the cost of plans and basic materials..

If you are unable to complete the scratch build you can allways buy a beginner level kit..

Remember something the main differences between kits and scratch building are detailed assembly instructions and prefabricated parts.

If you don't like your foam plane and think slab sided kits aren't challenging enough then just buy a set of plans and 20-50 bucks worth of balsa and have at it.

One piece of advice building airplanes is one aspect of the hobby and flying airplanes is another.

Using your foam airplane for practice makes good sense in more ways then I care to list.. Your unwillingness to use it for trainning purposes confuses me.. Why would you risk a plane that took hours to build when you have a disposable one??

Anyway each to his own. Good luck and think about just jumping in a scratch building
