Alright, after working through all the fixes I know, I'm relying on you guys for advice.

Put my 450 up in good working order the other day. Pulled it out today, plugged in my battery and my ESC goes to first 3 beeps (align 35A) then nothing else.

Tried going full stick to reprogram but still nothing. This has fixed strange issues in the past but not this time. Its almost like it doesn't hear my TX. Not settings beeps, just the first 3. Servos don't move or anything.

Don't like to get stumped but it happens.

HALO

What remote are you using? Did you plug the esc in the right way and is it in the right channel? If your using a spektrum tx/rx make sure you bind it. If your servo's are not working either than maybe the esc went down south or your just not getting a signal

Nothing has changed as far as what is plugged in were. I did replace a servo but I've done that hundreds of times. Pop out the old one, put in the new one and do a complete head setup. I have a feeling that I'm doing something silly that is either making it think that there is throttle or something. Just can't come across what. Could be the ESC is just had it.

LOL! I'm using a 9c Super. Still on 72 mhz and loving it. Screw it. I'm just going to buy a new ESC tomorrow. There is no explanation for what it is doing.... but, if I figure it out, ill let you guys know. I'm not done yet.

Huh, plugged in a rx pack to bypass the ESC and don't have any servo movement. Think I just found the culprit.

Yep, plugged in a micro receiver and servos came to life. Weird how electronics can just crap out like that.

Time to head over to the classifieds to look for a new receiver unless someone in here has a R149DP that they want to get rid of.

So you get no servo movement at all? Could be a fried crystal but I think thats ruled out now time for a new rx

Just wondering. Did you check to make sure you were on the right model on your tx. Sometimes that happens for no reason.

Yeah it was on the right model. Reckon it was just its time to go. She has been a good one. Still on the lookout for a new one. Time to start the search.

Thanks!
