I know what a ESC ( electric speed control ) is and basically what it does
(controls motor -speed-direction- and possible braking )
Now a BEC ( Battery Eliminator Circuit )allows a battery to be used for multiple components and power-splits it however you wish to explain it. To allow One battery to Run a Motor and Radio, servos' etc etc etc....
They even have a UBEC ( Ultimate Battery Eliminator Circuit )improved version as it were to the ESC-BSC, thus saves battery power and helps keep them cooler
and SBEC that helps to use battery power more efficiently
Ok basics, Fine, now here is my question and I do not understand.
Many Planes and other RC products come with a ESC, but many do not come with an ESC w/BEC or ESC w/ UBEC or ESC w/SBEC whatever ?
What i see for example is, ESC: 20A w/BEC or it may say simply, ESC: 20A
I saw some even with, 2A BEC BESC ?
and a whole host of others with switches etc etc
But I see simple lets say Planes that have 2S batteries that show ESC: 15A /BEC and another with a larger battery set up say 3's or 4's and only have a ESC: maybe 15A or 20A
of course some higher, but never mention BEC or SBEC or UEBC....
SO what determines the need for the ESC to have BEC-UBEC-SBEC etc etc etc ? And how is that figured into the Model ?
Is it just manufacture's choice or is there and basic reason why one plane may have it and the next not.
I have seen some larger style planes say ESC 20A whatever and then a very small plane say ESC 10A w/BEC or something like that ?
And should one install a separate BEC-UEBC whatever unit along with their normal ESC and if so how is it attached in the circuitry ?
Now take note, my mind is slow and plain English ( for our across the pond comrades forgive my term ) is needed for me to understand....
Thanks in advance.

Get through that and get a grasp on it and you'll be ahead of 80% of the people in the sport. AJEAR has good info, accurate, and clearly explained. As you can see your question required a lot of explanation. |

lol Lost me long before you got to the question. I think I'll just plug in the battery and if something eventually f***s up I'll buy a new one. :-)

My brain hurt half way through the post!  Let's be grateful that we have Flydiver to take care of such things. And I wish I had been born clever, instead of remarkably good looking. Then perhaps I would understand. |

You don't ask for much do you? |

One can only learn by asking and finding out....don't like learning the hard way.It can get expensive

One can only learn by asking and finding out....don't like learning the hard way.It can get expensive That is simply not normal.  As I've said countless times in this forum, "flying is easy, the electrics are hard". People think they are taking the sport up to learn to fly. Little do they know they really are going to learn about batteries, chargers, glue, tape, soldering, and arcane electrical devices they didn't even know existed. Obviously, I find that some of the fun stuff. Exercise for the 'noodle'. If you are not willing to learn, you either pay the price in failures, or you jump on the Horizon Bind-n-Fly bandwagon and be happy, exactly what Horizon is hoping. |

I have built allot of balsa planes over the years.Most have no electronics at all. Never knew exactly what to do, still loved the plane build....most of those empty shells found there way into the trash simply for lack of space. Many found there way splintered on the ground cause i had no clue how to set them up and watched them go up and come down, in a bad way.
My desire is to learn enough to know how, not only to enjoy flying ( which was always a dream and now has come true ) I also wanted to build and install my own electronics, and know how to and to do it right in my own built planes at some point . Why I am asking and trying to learn as much as I can. My issue is the retaining of that knowledge.
I can get it today, but tomorrow , i may not even remember part of it. Going back reading forums and posts helps in that problem i have. And why i ask so much and so often.
I desire to learn the right way to have fun doing it.

And why i ask so much and so often. I desire to learn the right way to have fun doing it. Sounds like what I have...only worse. I don't envy you the issue though and give you credit for trying to work through it. I have a HUGE RC file that is all organized in folders. I also have a massive bunch of links, also organized. That's the way I deal with it. There is way too much info to remember it all-no one can. People tend to specialize. One clue is to find out who those specialists are, then follow their advice. Most of the rest is just static. If you have lousy weather, no ambition to build, read, harvest good info, and organize. I personally work on a conceptual basis. I can't remember the facts, but I can remember that I know something about an issue and generally go find it again. Some of those huge threads like the last couple I posted are great for a wonderful overview of aspects of the sport. You STILL have to dig out specifics for individual planes. Generally you can find that in the first 5 pages of any RCGroups thread. The Super Cub Club has too many newbies so the questions are mostly repetitious and all over the map at any given time. It makes it hard to organize. OTOH, once you 'get it' the principals for the Cub are relatively easy. I know you don't much like the other groups behavior but the info in Super Cub is pretty limited. Get a callous and learn to ignore it. |

Hard to go from multi-tasking to not even knowing how.
Frustrating to say the least, for me anyway.
It's not so much of not liking other forums I still go over and read and on occasion make a comment or two.....But when you ask question and your an idiot and worse than a criminal for 15 pages before someone comes on there and gives you a legitimate reply, there is where the issue is.
I have not had the internet that long, nor have compiled any information. For so many years, I had notes attached to everything, just to remember what i was suppose to do.
Last year after watching some video's, I decided to try and get back into RC, something I had not done in years. I had an Old J3 Cub in the rafters of an old out building still left over and some boxed up kits. Thought why not. I did not know about the foam planes and all the technology there is and how far it has came. It was like a kid in a candy store.Went sort of overboard in getting planes I liked , rather than planes i could fly .
So just being able to fly something, was a dream come true. The Champ and Cub made that possible.
Would still like to repair the old J3 and get correct electronics in it and a few of those other kits i still have.Would be nice to learn that side of the hobby, rather than just buy X-Y-Z and never know how, why, when.....Why I asked about the ESC -Prop info and what is best for what and how is that determined.
Again Thanks Fly.And that is why i ask here. I know you will give me honest straight foreword information without having to go through pages and pages of how ignorant I am before I get a real answer ( as those other forums seem to provide )Lol.
i Appreciate your help.
