Personally, I decided to go with an 80 ESC Pro and an EC5. I could be totally wrong, but seems like a lot of juice for an EC3. Anyone else have any issues? HH mentioned no other reports of this yet. Did I mention how nice this thing is to fly?
I've got over 50 flights on my 6S 500x helicopter with no issues, I never bothered to change the EC3 connectors. I've been using an XT60 to Deans converter. I can't imaging that this cub is putting out any more current than a 500 size heli although its not possible to measure the current on a heli without some sort of downloadable ESC. I have yet to maiden my Cub.

If it's a short at the EX3 connector, AS3X should not have worked, and the motor should have been off, so the airplane should not have went 3/4 miles away? I believe EC3 are rated for 60amps. I would investigate something else before flying it again for sure.

Line up the colors when connecting as the connectors may not all be oriented the same way. On mine, 3 of the 4 have the orange wire towards the front, while one has the orange aft, so I have to visually inspect each time and align the colors accordingly.

That does seem like a pretty good price. I'm concerned about where they ship from. If it's China, those batteries would probably take a month to arrive. And I've never heard of that company before so no idea how they are to deal with. Seems like there are new companies in China popping up every day and a lot of them are related. Some seem to have better service than others.

I'm kind of interested in this one. http://www.dealmetic.com/product.asp?ID=RC03175Because it has a EC5 connector. Would save me having to purchase and solder the EC5s. And I wouldn't mind that at all. Plus that one is 40C. Not that I think we need the extra C rating, but it never hurts.

Yep - the default ESC programming is set for 6S. To change to "74% mode", you have to program the ESC from your transmitter. Instructions included with kit. After changing, instead of hearing 6 beeps (cell count), you'll hear a little melody when you connect the battery signalling 74% mode.

And that's 74% of the battery voltage at the time of connect; so if you land, disconnect the battery, make a necessary throw adjustment, and reconnect the same battery, the cutoff voltage may be lower than the safe level.

Always use a freshly charged battery when using the percentage method.

It is coming from China, shipping is about 15.00 for one battery, so it's about 50 for one shipped.

never heard of them, not inclined to try. There are 2 companies I use in the US that ship almost always on the same day, don't charge and arm and a leg, and have pretty good service overall. Valuehobby dot com is one of them, and he has this size with the ec3 already soldered on. The other is China Hobby Line dot com. His prices are about the cheapest, almost always has free shipping, offers other discounts, and usually gives a lipo bag too. he ships priority too. He has two locations to buy from, Hong Kong and USA...Beverly Hills actually. I love his batteries so far, I use them for my ducted fan planes.

I also looked at the Hobby King site (USA) for some batteries as well. about the same prices, give or take. Not a big fan of their shipping charges and I don't seem to have great luck with the US warehouse. I've done some through MotionRC too but I don't know if they have 6S.

Add headsuprc.com for inexpensive, prompt, shipping.

You are right about the as3x...I hadnt thought of that! I had some altitude... and this thing carried for a looong way. I went back and Google earth'ed it at just over 1700 ft. It is possible that I could have have a short, but I can easily say the connector caused the shutdown. (for whatever reason) The EC3's were physically bonded together. For me personally, I'm not going to chance it. I'm gonna get the 80 esc with EC5. it may jsut make me feel better....

I still think this is going to be one heck of a plane...
