Mine should get to Castle Saturday/Monday so we can find out what went wrong after a week or so... I'm hoping

Cody, not arming was the first "odd" thing my XL did, you may just want to sent it in as well
if you don't see any really obvious solder joint, radio problem, bad servo, bad connector, ect.
Mine did arm again after cycling the power, but it only went 20 feet plus 2 more before it was in flames.

I've went over my rig with a fine tooth comb and haven't found any issues.
I'm going to double check the resistance in my 1518 at work today,
forgot to bring home my meter trying to get my XL shipped out last night.

P.s. sorry for the jinx, I was actually hoping I was just unlucky
but having another person that's having issues really concerns me.
Please consider sending it in, or at least benching it until we have an answer on mine,
it could be that yours is in the first stage of whatever lead to the death of mine.
