Quark UBEC for my Neu 1515 1.5y/s brushless system ; 5A or 6A? which way should I go?

Do I need a bec on my Quark Monster Pro 125B running 4s 14.8v

[BrianG]

Yes. Any battery voltage over 2s (or 7 cells) needs an external UBEC IMO. Any battery voltage higher than 2s causes excessive heat and just is not worth taking the chance of getting built-in BEC thermals or worse.

Do I realy need a bec with the monster pro 125b? I will stick with my MM then.

So this esc is available in Korea? I saw pictures of it almost a year ago but then never heard anything else bout it. I realy would like to see one of these IN person. How has it worked for you. I love the hamdheld programaing device.

DO you have any idea if they plan to sell it in the US anytime soon?

Here is the link to the page. This is the one you have corect?

Right that's the one.
I find the handheld device handy.
But I am not sure it is good for a big truck like E-maxx 16.8V because the manual specifically states that it is for 1/10 cars and Quark won't be responsible for any problems that occur by using bigger cars.
