Mangoman...keep an eye out for SpeedZoneUSA RC...they are going to release a 5000mah 1s brick pack shortly and I know Gavin is working on a design for a 1s Lipo Saddle Pack for t-bar chassis.
I'm in the same position as you, having recently invested in a CEFX Pheonix (t-bar) as well as my trusted speedmerchants.
Quick question for you asphalt racers. What's a good starting tire combination to use for 1s Lipo racing...prefer to use Jaco Prism's as track width is set for Jaco's.
Will likely go to the Region 2 electric outdoor regionals and prefer to keep tire cost at a minimal. I was thinking Lilac / Pinks?
