yes its an AM radio

so hopefully its just that and nothing else.
i was wondering, i've had my jato for about a month now maybe a little longer, but i hadn't really broke anything yet by wrecks or jumps, untill today where the throttle servo mount is cracked. but i was wondering how did that crack?? looks like something else would have gave instead of that ?? is this normal for them to crack that easy??
and also is the flexing of the body normal when applying throttle?
