Great... more sodding problems...

So, my problem is... Ratatoskr refuses to move.

I know I've got power going to the Tz85a ESCs for the locomotion, but instead of the three normal fast and loud beeps, they're replaced by three low volume slow beeps. I know for a fact that that ain't normal, so can anyone tell me the problem?

Also, I think the radio receiver's shot to hell, as the light refuses to appear upon the thing when it's all powered.

One final question, is the LED light mandatory? As I think the ones I replaced them with shorted out... and if that's the case, then I'm going to have to go on the hunt for more LED lights that can handle 18v... or as the battery charger likes to say "21"... not sure if that's the actual voltage, but okay...
