The Tiger Moth is a fantastic plane. Crashem is right about the lithium batteries. My lhs has a lithium pack and charger for only about $10.00 more than the NiMh setup. The downside is it's a three hour charger. But with two packs, I don't think you'll ever be bored. Thirty to forty minutes in the air is a LONG time. You'll be ready for a break pretty quick. The lithiums have no memory either, making them much harder to damage. Cheers.
