some have worked with external, mine will not power on with external power.

I'm considering putting an external bec on mine when it arrives after the luck I had with the first.

The initial production was way more than 50-60 units.... I thought i heard something about 1500 once. I saw at least 200 myself at the shop the other day.

Sounded like a BEC issue, and I'm sure the guys will track it down and fix it. I wonder it the production units had a changed component from the prototypes, or a bad batch of components... something unexpected. It happens.

Honestly, I'm a little concerned with running mine now too... but that's the only way to find out how it's going to do.

just sent my monster in and it should arrive in kansas sometime next week....luckily i ordered one from mike and I hope its from the 2nd batch...:neutral: but castle has always had great customer service and make top notch products and I'm sure these dying monsters are just part of the regular mass production mishaps that happen with just about any product that is mass produced...besides only one of my batteries are 5s the rest are 4s.....and i agree with you too dickyt i might end up running the CC BEC once i get this one back just to be on the safe side...

I would just run it like you would normally, and if something happens CC will take care of you...they have a very liberal return policy, they will send you a replacement before you send them the defective part
