First you cut a whole bunch of balsa sheet stock into the appropriate size sticks you need to start your scratch build.

Then you start paying them out in the shape of a fuse.

Before you know it you have two fuses done since your building them for two different people.

Then you build a rudder

Then you realize while you have all the stuff laid out you might as well build three of them.
That's all for now.

And if you're like me, you only get to sit back and watch other people build a plane . . . . . . .

 

[BalsaDust]

Getcha something to build then. Oh and mind you these three are all scratch built.

 

[BalsaDust]

Build another fuse to make the total three.

Build another rudder

Before you know it you have 3 fuses, stabs, elevators, rudders, and motor mounts.

Lay a fuse and rudder over some clean butcher paper to get nice tracings of so you have a decent set of plans to build off of.

Yup you guessed it, fire that bandsaw back up to make all the 5/16" LE and TE sticks. Enough to build three now.

Lay out the ribs and all the sticks and hit all the joints with thin ca.

Sheet the top of the wing and get ready to flip it over. Once flipped I will get some detailed pictures of the main spar as its a modified design that makes it super strong. The prototype only has shear webs in the first two bays and it has been cash dropped, walled, and cart wheeled more times than I can count and still holding strong.

Do you go to the Harrisonburg va fly in?

 

[BalsaDust]

No I have never been to that one.

@cbarnes0061 wonder I f you could help. Have a AW - prox-260. I know that you are not impressed with the plane. Would like build a new wing for it if you could suggest a profile for the root and the tip to improve the planes performance and the size of the alerons. And what wing loading you strive for. Thanks for the help.

 

[BalsaDust]

Ok sorry if I misled you. I have never flown the AW plane so I do not know how it flys I have just heard bad things about it from the probro site. Guess the biggest thing is the type of flying your looking for when it comes to WCL. I like a nice floaty plane but at the same time I have one slab that has a higher WCL that freaking kicks ass. What helps it though is its still light wieght so while it may not be floaty its stable in high alpha which is important. I will post more in a bit. Out with the wife right now.

Hey Chris, You're BRAVE man. . . . . . . BTW, where did you find the brass bar stock you cut up and are using for building weights?

Thanks,
