70mph...I see that you're in Edmonton...
Your best hookup for batteries is likely going mto be Walmart...
a 4-pack of Energizer 2100mah NiMH batteries will run you $15.64 Cdn if they hold the same pricing strategy as here in Ontario...
I'm running those in my R-1 and get LOTS of run-time between charges...and if they'll last in an R-1 they'll last FOREVER in an XR2
