Ask away anytime :). Take a look at this image. Each battery cell is 1.2v 1000ma. This is two sets in series. Having two parallel sets, and two series. The series adds up the voltage, parallel adds the capacity. If you peel the skin off of a 9v battery you will find that there are 6...

Larger propellers with low KV motors are generally more efficient, you may try playing around on ecalc to achieve best efficiency. http://www.ecalc.ch/xcoptercalc.php

I figured you'd say that, as the two frames are like comparing apples and golden apples :). The frame really does look nice. Just curious, what type of setup do you have planned? I think that it will be interesting to follow.

Anytime, there are multiple people here more experienced than me who can help also.

Also, here is what I did for my frame. I dropped the spring loaded gear because it was heavy, and the above pic has a little give.

Wow, that frame is really up there. I have never seen such a frame, but it looks functional. It might be cheaper to get a similar frame to this http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=66610. That way you could put more money into the brains and transmitter. That is...

Same here xD.

Welcome to the forum. Wow, that looks pretty complete list. I can't say anything about the flight controller, as I have heard nothing about it but it looks good and is at a cheap price. Reviews seem positive. The radio is cheap yes, but it has been known to have shorter range than other full...

Oh no, the epidemic, I think it is spreading! I really think it is great. It can be upgraded later and looks fun. I think the frame is a little pricy, and it is out of stock. After looking, IMHO you'd be better to get all of this from HK. But as far as what is here it looks great. Do...

HA you finally joined. Told you would be addicted once you started learning more and more.

Addicted, anyone know of an RC's Addicts Anonymous?

Lol, I agree 100%. Here is a great app that lets you feel as your flying. I used it to get used to the controls.

Yeah, those take up less space on your quadcopter. I have the hobbyking 30a ones, but the 20a are cheaper, you need a minimum of 20amps for your motors. The 20a will do 25burst, and your motors will burn out before that, s othe 20amp ones will be good. Most people say you need at least 5amps...

Your ESCs are probably fine, but you might be well served to get some with a BEC on board, to save on money and weight. I like 30A ESCs because you don't have to worry about them being burn't mid flight or getting very hot. But that is just my opinion. 4S may give you a little more lift if...

Lol, This sounds familiar. I was planning for $250 for my build. I am now around 520, and plan to upgrade very soon. this is all before my first real flight with that quadcopter.

Yes, just check your motors. Your motors can use 2S-3S, but not 4S. Your ESCs can use 2s-6s. Most people don't use 2s, but you can if you want to. The S is how many cell sets are in paralel in the battery. A lipo cell is 3.7V. EDIT, Watch out for this ESC, I just read a few reviews and...

Yes, you can use them. I like these. As you can see by comparing the specs, yours have a higher C rate, but are 2S. Most quadcopters are 3 or 4 S. Yours are 7.4 volts. If you wire them in series you can use them as 4200mah 4S batteries. You won't have to worry much about puffing them by...

There are cheaper versions for the transmitter, I bought one such recently. But now I am buying a SPEKTRUM DX6i, after not even having 20 minutes of usage in the cheaper 4ch HKtr6a (Hobby King). It did not break, I just really don't like it. I now wish I'd gotten the Orange or Spekrum and...

You can make it a little lighter maybe, but I don't believe enough lighter. If you make it gear driven it might work, but you'd have to find the gears for the chance of it to work. If you have an old VCR they are full of goodies in the way of gears and whatnot. I forget where but I say where...

Take a look at this link. It is a glossary for basically all of the terms that you will encounter here on the forums. Here is a good calculator for helping you decide on parts.
