power question

[DwightSchrute]

i've got something weird going on. on one of my mmm setups, i'll plug in the battery, then turn on the radio, then the esc. then i turn on the on switch. then I wait for it to arm, and it does. then...nothing. no throttle, no steering. however, the mmm light is on like it was armed and ready to go.

now, here's the weird part. if i unplug it and then re-plug it in, it will power up fine. i'll get full throttle and brakes, and steering.

it seems like the receiver isn't picking up the esc on occassion. anyone else have this happen?

the radio batteries are new, and i'm using a spektrum dx2. but i think it's an older model receiver.

is this an esc problem or a receiver problem?

any other ideas?
