Don't forget about glue weight aswell!! that will be another 2g.

mine came out at 95g which gives a .4g/sq. in wing loading. If you can keep your wing loading around that, you should be fine. Their is 210sq.in of wing area on my 20" ws version, and that isn't taking into account the fuselage cross spline that the hoverflaps are incorporated into.

Here is my Cox/Gravity Warbirds Zero. Got my 5g motor from HK on Friday so I can get back to this since I stopped working on it a few weeks ago.

Left to do are the Ailerons (I'm going to do dual servo Easy Flaperons) and engineering the landing gear, but the Fuselage electronics are all in and the fuse is buttoned up.

AUW is going to be right around 4.2 Oz in 5 channel mode (A/E/R/T/F). The 5g motor seems to have a lot of power and it should fly like a Warbird. The 2S 360 Rhino gave me 7+ minutes at WOT throttle with a 5043 prop in bench testing so flight times should be Huge.

These models are great fun to build and modify for cheap so I ordered 3 more today.

That wing area doesn't really help becauyse mine is 6" smaller. I can just get LxWx2 and get wing area. 4th grade math! Go me!

Looking great, so can the Ar6400 handle a 2s lipos without mods?

Yes and No.

The AR6400 isn't modded in any way, but you run the Brick off the BEC of the ESC, with a Voltage dropping diode (about $0.25) in the Positive power wire of the Brick, then run the signal wire to Motor plug.

That won't give you the area. Because of compound curves or basically your wing isn't exactly square, and even if it was, that formula wouldn't give you it. Its just WxL, i don't know where the 2 came from. Give me you plans, and i'll grid it with one inch squares then work it out for you.

for finding the wing area on mine, i averaged the root chord and tip chord (6" and 5" respectively) and multiplied this by the span. which comes out to 110 sq.in per wing. its not 100% accurate since the wing has a curved LE, but i have found its close enough, and quicker than counting squares

I did x 2 because there are 2 wings. Remember? I will just do the square counting method.

Mostly inspired by leadfeather's Yak 55 design (which just rocks BTW). I also stole the decoration scheme in his thread.
