Rechargeable AA (1000 Mah) Ni Cads run about $0.95 ea. and NiMh (2300 Mah) run $1.87 ea. from all-battery.com and if you buy in lots of 10+ you can save even more. I have a professional quality microprocessor controlled Maha MH-C801D quick charger that will charge 8 AA's of any type or capacity in 1 hr. so rechargeing enough AA's to keep from going broke buying alkaline cells is not a problem. Run time on this tank with freshly charged cells is reportedly around 30 mins., so keeping enough charged cells around for say two half hour runs won't be a problem for me. I would have preferred that it ran on the 7.2 volt Sub-C cell packs like the RC Pershing, and I have heard at some of the RC forums that people have converted these to run on the 7.2 volt packs, and even the 9.6 volt AA Nimh "robot" packs, and it already has the Tamiya mini connector in the battery compartment if you decide to convert it, but personally I don't want to fool with a conversion like that just yet, but maybe later. Good quality Sub-C packs can run from $15 to $25 ea. (and up) depending on manufacturer and capacity, so there is no tremendous advantage cost wise on the Sub-C packs versus AA's that I can see, plus they take
FOREVER to charge (4 hrs. minimum) with the chintzy wall chargers that comes with the Hen Long tanks. As for the IR battle system...it's been raining here for like a week straight now, but as soon as the sun comes out I'll let you know how it goes LOL

The gun recoil looks and sonds fine to me, but I've never witnessed an actual T-34 firing, so I can't really say how realistic it is...

There are some You Tube videos of this tank in action if you're interested in seeing it doing it's thing. All things considered I'm very happy with it, and would recommend it to anyone who is getting into RC armor, it's really quite nice right out of the box, and has plenty of potential for additional weathering, detail, and add ons like metal tracks etc.
