The quickest way to 3D is foam....period. The SIMs are getting better, but foam is REAL.

I have flown these kits for almost 2 years now. If you want to learn 3D, this is the way. It will transfer to glow (yuck)...and real 3D gassers too. Just remeber that your Power to weight ratio on foam is far better than on gas or glow.
Good Luck!!
