ok if you are building an arf yea its possible, but that basicly isnt building, thats just turning some screws and waiting for glue to dry
on the other hand if you want a kit, .40-.60, no way will you have the time to build it
if you really want to do it, try something alot smaller, sig Rascel(not sure how fast it builds)
and this is nothing like building an rc car... i have a t-maxx that is taken down and back together in 12 hours, with a plane kit you are looking at 4+ times that, and an arf in about 10-20 hours (depending on the plane)
i also dont think you should do it... like was said, crashed into school, car.... that would go against everybody who flies not just you....
thats my 2 pennies!
