OK, That 14 AWG wire is quite thick - You won't be needing that much. I'd go with 16AWG.

The connectors you selected are not compatible with the ones HobbyKing uses on all their batteries - if you are going to buy batteries from them I suggest you get these for bit more:

http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=18448&aff=524347

The 30 Amp ESC is matched to the motor - but it's good to have a higher ESC rating than the motor states. Then it will run cooler. However the trusted brand is not in stock - as usual:

Thank you!

I'm gonna buy the batteries here in Belgium. End here are the most batteries with T-connectors. :)

Yeah all those items will come in handy, when I first started it took a few months to get a decent inventory for scratch builds, alot of it is you don't realise what you need until you go to do something. Some handy tools that I use are a prop balancer, a servo tester, a reamer, and lastly a hand drill.

I wrote a request last week about putting a clip together with some advise on how to pick motors and the relevent electronics to go with it. Once again I think it would be great if Flitetest put a video package together for us "newbies"!
Does anyone agree?

Those are pretty big bullet connectors, you could drop down a size to the 2mm and go with 16g wire and save some weight. I also suggest getting away from those t connectors. They don't handle the amperage of the XT60's and it even has a Alert on the page saying not to use these. I would suggest going with the XT60's available from hobby king, I would also suggest using their turnigy batteries. That's all I use now, for all my models. They are awesome. If you really want to use the t-connectors, go buy some Deans connectors or other high quality connector, not those. Poor connectors will cause heat, melt, potential fire, or at least a high amperage draw and affect your performance.

Aside from those two things, looks like you have the start for a good scratch build. Remember to repay for advice. We take VISA, PayPall or pictures of your builds. We especially prefer video.

I couldn't agree more! I have no idea on how to combine motor/prop/ESC in harmony for a given plane size. It seems like all manufacturers use different nomenclature and numbering systems for the motors they produce and it has me baffled. I have asked for this on other sites as well, and basically been told it comes with experience.......I don't have experinece! And I won't unless someone can find a way to cut through all the jibberish and spell it out a little more clearly for mental midgets (no offense to any little people out there) like me.

This is a great idea that would really help guys like me when putting together a scratchbuild or trying to eek a little more performance out a particular plane. Thanks for letting me rant a little.

Thnx for the support Dave,

I was starting to think I was the only thick brick in the building! I have two scratch builds on at the moment, a delta wing and an F16, both I have found on different forums. I'm basically working off the plans when it comes to choosing the running gear, but I would love to know what else I could do if I wanted a different result.

I thought that both the post above and the original thread that I posted last week would have had a lot more support but it appears that everyone else must have all this stuff worked out...Go figure!

Guys, It's not that everyone has everything figured out but there's a lot to know. It really does come with experience, but instead of just telling you that, I'll suggest giving us more specific questions and I'm sure you'll get lots of replies. If you can give us your specs and tell us what you're going for, we can offer more specific advise. Most people don't have the time to write out a lengthy explanation of all things related to power setups. Putting all of that into a video would take forever and would probably be more confusing that helpful without making it an hour long. Don't be offended if people aren't jumping up with info on this one, it's just a lot to understand and explain.
I tried using the search function but it's difficult to find the threads we used before to explain this stuff. Basically, start a thread asking about specific parts you're looking for and you'll get more response.

I don't know how much you already know but things to understand are
Batteries (2s vs 3s, C rating etc)
Motors (kv rating, kv related to battery cell count, wattage and amperage)
ESC's, (pretty simple but you need to know about BEC amperage)
Props (lots of trial and error there, but there are some guidelines, usually related to motor wattage)

So figure out what you need to know and get back to me. If you want a full tutorial then let me know but that will take a bit longer. You should also check through the articles. I think a couple people are working on articles on this topic.

I know exactly what you mean, there is a lot of numbers when it comes and you really need to have a basic understanding of electronics to really get a grasp of how to setup a power system for a plane. I did electronics at college and it still took me about 3 months watching youtube before I really got a handle of how it all works.

As AK Flyer said , the best way to tackle it is one question at a time.

What helps the most (for me) is easy algebra (calculating with letters) and doing the calculations with the complete unit letters. Something that needs to be taught is that motor and prop combinations can't be predicted, they have to be tested. Thrust numbers and such are the case there.

Good points. I like to use Turnigy easy match motors from Hobbyking and Suppo motors from Altitude Hobbies. One thing you find with these are a lot of data already in the motor specs. They include thrust as tested with different props and recommended ESC's props, batteries etc. so the initial setup is a lot easier and then you can tune from there.

AK,
Believe me, I know it would be a truly daunting task for someone to undertake this type of tutorial. If it were easy we wouldn't need the help, LOL. Also, I wasn't trying to say that people here were not being helpful, so please don't misunderstand my comments. I am very happy with all the helpful folks here.

The point I was trying to make is that I wish there was some sort of pattern or template for the naming / numbering conventions used by all the motor manufacturers so that it was easier to cross reference from one brand to another to find comparable power supplies. I guess the Kv rating is one way but there has to be more to it than that I would think. I'm sure the type of aricraft you are building, weight and size figure into the equation as well.

But if someone were to put together a tutorial series, maybe someone has and I missed it, that told / showed:
1. How to properly get your wattages, amperages and voltages and any other pertinent info...
2. What they mean...
3. Why you need to know them...
4. How these numbers figure into the subject...for example, you said props are generally related to motor wattage, but I don't know to relate the two.

I guess you could say I need the RC Electronics for Dummies tutorial. I do have a basic understanding of batteries and what their numbers mean. And why a BEC is a good idea. And what the Amp rating on an ESC is for. But you lose me after that.


I am rambling now, the cold medicine has kicked in and taken hold...

I'm pretty new to RC stuff, and it all started with David's Tricopter 2.5 about 3 months ago. Then I saw about how you could build planes out of $2 worth of foam, and am hooked bad already. (just put in my 6th hobbyking order a few minutes ago!)

If there is one thing I've learned, is that you absolutely need a wattmeter if your going to scratch build. You can start with recommendations of existing plans, but if your going to try a motor/prop combo that noone has done before, you NEED to know how many amps a combo is pulling. Whatever motor you want to buy should have a max amp rating. Get an ESC that will handle that amperage with a little safety margin, and then start measuring amp draw with different props. I started off wanting exact information about what to buy, but to be honest, for scratch building, your almost going to need an extra set of parts just to test with.

I got this one from HK- at $18, you wont find a better at that price. The closest I found locally (US) was $40-$50.

HobbyKing HK-10 Wattmeter

I realize that most people don't have the time or maybe even the expertise to put this together, but Chad and his team put some fantastic videos together and putting tutorials together is what they do. I wouldn't expect a single tutorial to cover everything, but maybe a series starting with what motor to pick and why. Then maybe follow that up with how to work out what voltage you need from a battery and what ESC to use.

Chad has asked many times for requests for video subjects and I think that this would be a great series of videos to make.

I have read hundreds of articles over the past few months and I can't work out whay certain motors are chosen by builders. My first thought is always along the line of why don't you use a bigger motor? I thought that bigger the KV number the fast the plane can go, but I gather there is more to it than that. I'm in the process of building a Delta Wing with a wing span of 30" and when I started researching the running gear I find all kinds of specs being used. Just some basic starting points would help newbies out so much. From there the specific questions could start.

When all is said and done I enjoy the interaction that this forum offers and I thank everyone for any help they give, either in the past or in the future.
