Brushless Revo or brushless CRT .5 help is appreciated

[gixxer]

I ran the 8t on the track today but only 1 battery. They both handle really well but the crt.5 was basically bought to play around with on the smaller track in back and hopefully the indoor track during the winter. I am sending my mamba in tomorrow for repair so it might be a little while before I make it back there.
