I just bought a Sprint 2 off a guy and it worked fine when I bought it. I put a Ni-Cd 7.2V 2000mAh battery from Radio Shack in it today (don't know how charged it is, but it worked fine in my Slash) and found 2 problems.
1. I can't find an on-off switch. Does this thing just have the battery plug serve as its switch? I looked on HPI's website and didn't see a switch in the pictures there either.
2. When I plug the battery in and turn on the controller, the car is immediately in drive. The steering doesn't work and the throttle will not back off, even with the trim knob. It's like the receiver has gone out or something.
I'd planned to buy a Spektrum system, but was going to wait until Christmas to do so. Does anyone have any ideas about what's going on? Like I mentioned, I pulled the battery from my slash and the controller batteries from the slash controller, where they worked fine, and put them in my sprint 2 and had issues.
Thanks in advance for any help.
