Raul,
It will all work out well. You only need to buy the charger once and lipos just now and then. Planes are a different story. May crash and need another one if it can't be fixed. Or, you may get hooked and decide you need 25 new planes.
I don't need any thanks. Just AJ for finding you and Brad and Kate. Kate gets a bunch of praise. Knows how to put together some real power on a budget. And all of my planes do well with his recommendations.
