i just spent the last 8 hours doing some power-studying on batteries. almost went with a trueRC order, then trakpower lipos looked good, but i finally decided on a pair of a123 racing packs (each pack is 2s2p, 6.6v, 4600mah) and their hypersonic charger. had i gone lipo, i'd have to buy balancers to add to my Ice chargers, the lipos, and a LVC. now i can sell both of my Ice's since the hypersonic charger/balancer will charge in about 15 minutes.
mark - the weight isn't bad at all. right now without batteries it's at 10 lbs. 8 ozs. That's not great, but it's not bad considering i've got an all-aluminum rig with 40 series wheels/tires, a wing and aluminum wing mount, and a 5 cell rx battery.
doug - i'll send you a PM on the remaining IB packs i have.
the batteries and charger should be here by this weekend!!!
