Okay, so I finally got around to re-wiring my drag car, so hopefully it doesn't burn up again...BUT, now that its all rewired with a new PCB, I ran into a few problems.
A) Dont know what MHZ the new PCB is

Any way to check that?
B) I tried 3 of my remotes, 27MHZ, 49MHZ and 57MHZ, none worked, Its all wired up right, but it wont work.
SO, can you fry the batteries too? Maybe thats what I did is toasted the batteries as well as the PCB?
Any help would be great. Thanks!
Ok, now the details for those of you who dont remember my drag MS.
Its a completly custom extended chassis, AWD, 2.6 x2, 3.6V Drag car. STRICTLY straight line, I.E. has 0 turning capabilties, its built to do the "1/4 Mile" and thats what it does (Quite frickin' fast while it was running too

) But now its dead, I'll rewire again tommorow, hopefully its not the batteries, because i dont have 3 more of the same kind.
