IMHO, both of those are a waste of your money. They'll work, but the charger can't do anything but charge those low capacity NiCds. It can't cycle test your batteries or fast charge them at the field. And the battery is enough for your trainer, but if you do what 90% of all beginner pilots do and transfer your internals to a sport plane when you either grow tired of or wreck your trainer, you'll find yourself wanting and possibly needing something better. If you buy those items they will get you in the air, but you'll be tossing them aside and rebuying when you advance in the hobby.

If you like buying from Tower, get this charger and this battery:

Or go to www.hangtimes.com and get the same charger and their top quality NiCd in roughly the same capacity.

Yes, this is more money to spend up front when you've probably already spent as much as you're comfortable with. But this is also equipment that you won't need to replace next year. The charger in particular will grow with you into every area of RC you get into, and I've already told you how it can save you an airplane. It's a must have piece of equipment, IMO.
