Castle Creations is generally considered to be the "Rolls-Royce" of ESC's on every forum that I have ever followed.
Clearly, my opinion does not matter.

it's easy to dismiss them sometimes given the method of delivery/rebuttal.

Things were finally back to normal and I'm willing to bet some people came back to the thread (like me as I was here from the start), but then this:

If you are already writing an apology for the post before it's even posted, chances are it shouldn't be posted.

You are correct. I edited it. Thank you.
Happy now?

After swapping everything many times, it comes down to everything works great with no problems if I use a 10A ESC. I several know low amp draw servos and no change. I monitored all changes with a watt meter and I am not exceeding the 1A rating of the ESC. So, the obvious problem is the ESC's (2). Does anyone have any idea what is going wrong with the insides of the unit?

The reason I ask is because I would like to "fix/modify" the ESC's to work properly just to learn something new.
I have had this only one time on a "Hi Model" ESC.

This situation usually manifests in the event of a high temperature being detected or a fall in volts lower than what the ESC is looking for.

If the ESC has not been programmed to accept the size lipo which you are using (2 , 3, or 4s etc) it will auto detect the pack size on connection each time.

It could be a problem where the auto detect has not worked correctly and the ESC is seeing a too low voltage input after using the throttle and the drop in voltage of the pack is being detected too early by the ESC.

When you push the throttle stick to off this resets the ESC and then you can power up the motor again, this is registerd with the "Beep" and usually does all this within a 2 second period.

I can only suggest to try manually going into the program mode and setting the ESC to use what ever lipo cell count you are using.

I don't think it will be a temperature issue if both ESC's are doing the same thing

6. Agreed. It does it within 10-20 seconds most times and when I land, nothing is even warm.
5. I had not thought of that. I will try it and let you know. All of your post is excellent information IMO. Thank You.

You freely admit burning out the ESC by overloading it yet you had no problem demanding a free replacement from Castle Creations, one of the most highly regarded manufacturers in the industry. After getting that have said that you would never again use a CC ESC. Go figure.

This is not a personal attack - just a statement of fact per your posts.

Dooooohhhh!!!

OK guys here it is, the Super Sky surfer death dive.

Super Sky Surfer air crash. (0 min 47 sec)


First the motor went out a few months ago, changed the motor and ESC

http://www.hobbyking.com/hobbyking/s...ner_Motor.html

http://www.hobbyking.com/hobbyking/s...ESC_Opto_.html

Redbrick did some funny things would run the motor for about 10 seconds the beep and stop the power to the motor...very unnerving. Changed back into a turnegy 50A programmable and this happened. Oh well, had a 5000 in the front with gopro setup and 6 ounces of lead and it still looked tail heavy. Has BHobby made any changes to the model since this thread started?
The batterys survived but everthing else was toast.

Anyone need any scrap EPO foam?

Ugh..that sucks. What the heck happened? Thank god it veered toward the sand and water instead of the homes. It looked like it impacted the sand then did a little hop into the drink.

My less than death dive

Since you can see the wing to my SSS in the back of the truck, (left hand side) I think I can still post this.

One of my Bixlers. Went up, flew for about 15 second on 3/4 power. All of a sudden it went dead. Everything went dead, no power or control. So it starts porpoising on the way down and for a second or two I'm thinking it might actually come in at the right angle. As you can see, not so much. Luckily it's all tall grass that has been windblown down and deer use it to run around in, and it's pretty thick so no damage to the plane.

I've been wanting the get the SSS in this area but this was the last flight I had there, perhaps someone can give me a thought on this odd issue.

It's a pretty good sized field, no cell towers or anything like that around, just some homes on three sides. At three different times, with three different planes, using 3 different receivers I've lost power after about 20-30 seconds of flight. Complete shut down, no control at all. Sometimes it's on the first flight, sometimes it's the 6th or 7th. It's always at this field though. All different batteries and esc's too. The only constant in all of this is my transmitter, a DX8. But I've never had the issue at any other field. The receivers used were all OEM Spektrum too.

I've heard of FM signals being "jammed" or shut down, but can this happen with 2.4 as well?

Thanks!

Yipes. That is very unfortunate. That is exactly what can happen if you accidentally overamp an ESC which is probably what happened. Then, the overamp/overtemp safety mechanisms in the ESC will stop the motor (or entire ESC). When the overamp/overtemp part of the ESC does not work, fire is a possible result which is what I keep getting hell about. A CC ESC of mine failed because of that and one person is still tweaked because I returned it. Hmmmmm...
What prop did you use with that motor? Did you run the numbers with a watt meter before you flew it?
